BlueDriver Bluetooth Pro OBDII Scan Tool for iPhone & Android - No Subscription Fee - OBD2 Car Scanner and Code Reader - Diagnose Check Engine, ABS, SRS, Airbag & 7000+ Issues on Vehicles 1996+

Been using mine for 3 years and it has been great. I leave it always plugged into my truck so that it is ready to use if I get a check engine light or even if I'm just curious about how the engine is running. It is well worth having, as it has saved more than its cost in not having to pay for diag time at the shop for minor problems that are easily fixed with an off-the-shelf part or when dropping off for things like the inevitable emissions sensor that goes bad. Being able to tell them "It's theowing this specific permanent code and it started on this date," before even taking it in saves paying for that time amd has saved time, as well, as they'll usually order the parts right then, so they can get it done a day sooner when dropping it off. 👌 For any code you get, it tells you what it is, likely fixes for it, and even shows a chart of how many people reported each potential fix as being what resolved the same code for them, PLUS usually a link to buy the part on Amazon if you want to. Also handy for clearing unimportant temporary codes that still throw a MCL/check engine light, since that's one of the only caution lights vehicles have these days, as well. Aside from problems, it can show you real-time data from the vehicle's computer for every sensor it has, which is pretty nifty even if you aren't using it to tune the engine or anything like that. You can gain insights into why maybe the engine feels rough or why it's not accelerating like you normally expect, for instance, by seeing timing information, engine load values, actual throttle position, fuel flow rate/pressure, more temperatures than you ever thought necessary, and more depending on the vehicle. And using it is a cinch. Just plug it into the ODBII port, fire up the app, and it'll find the sensor. Then, pick whether you want to see live data, scan for problem codes, add maintenance info, etc. It'll even show you codes that *don't* cause a warning light, which can help you get ahead of things before they become expensive problems. And it saves it all in history on your phone that you can export to excel or share with the shop or whoever you want. And it isnt tied to a vehicle, so you can just pop it into any vehicle, tap scan codes, and be done with it when your buddy complains their car is showing a check engine light. Overall a great product and does exactly what it claims. Couldn't be simpler to use, and has had zero compatibility issues with any Android phone I've ever used with it.

I have owned several scanners, this is by far the best. This connects to your OBD, you turn on the app on your phone and you are ready to rock. I am impressed by extra features that are usually only available on larger more professional models. I keep this in the car in case I am out or a friend runs into an issue. It works right out of the box, no batteries, no cords. It has numerous complex scans that you have a bit of a learning curve to fully utilize. For the price and ease, every simple function that requires a breakdown can be done in a couple of minutes. It allows you to reset codes, scan and even tells you of numerous potential problems. Then it shows you the part and part number to order for replacement. I usually run the scan then snapshot the problem, then reset and wait for the issue to appear again. Many times it just goes away. Always double check the diagnosis with chat GPT for possible other problems.

Excellent tool. It has already paid for itself 10 times over. Offers detailed description and definition of obd 2 codes and offers common fixes. Also has live data reading and some functions. Easy to use and works great.

This review is written by the husband of the account holder. She bought this for me as a tool to help diagnose a issue with our vehicle. So the following are his words and not necessarily shared by the account holder. My (Hubby's) thoughts on Amazon: "They are liars and I will never order from them again! They have done nothing but screw up the shipping of this product from blaming Lemur to just plain outright telling a lie! Yes they did refund shipping and compensated my wife for this crap but it will be a COLD DAY IN HELL WHEN I WILL PURCHASE FROM AMAZON AGAIN!" The shipping and lying fiasco is partially why the rating is low. Some of the rating comes from the product itself. So let me get the issues out of the way first and then I will get to the good things. Which there are more good than bad I promise! Oh and another disclaimer: Use this tool as a diagnositc aid only!! This tool and others like it help point you in the direction of a fix and does not explicitly tell you what is wrong. So please use this tool to help get you pointed in the right direction. Just don't replace parts, use the tool to get direction, diagnose and then fix. Now to the issues I personally had with this tool: The live data PIDS take several restarts of the application to get to come online. I'm not sure if this is because of a special issue with my vehicle or what the issue is. This is annoying but can be overseen. I personally am a impatient person and like stuff to work the first time around. The second issue is issues that I have with a feature of the tool called Mode 6. My vehicle supports this and I was excited to see what all I can see however this is where the issues arise. The first issue is the app on the phone locks up sometimes when trying to go into mode 6. This isn't cool at all. A restart of the app fixes this as well. However once I get into mode 6, I get PID/TID readouts that are not human readable! I get TID/PID numbers and the output is in HEXIDECIMAL readout. The HEX part I know from working with computers however without a TID/PID chart, the data is WORTHLESS! In Lemur's instructional video on mode 6, they show you tapping on a TID/PID and it tells you what it does. On my vehicle, it gives some generic message which again is worthless. So mode 6 on this tool is completely worthless to me! A issue that seemed to correct itself through use is the repair reports. At first, I could not get the repair reports for the error codes on my vehicle then yesterday 12/29/15 I tried again and I was able to get the reports! Coolness! Now onto the good points! The tool will work with both Apple and Android mobile devices. I only was able to test on an iPhone so I cannot say how good or bad the Android device app is. The app and tool are updateable! As Lemur finds thing that need to be patched, they allow the app and the tool to be updated which is very nice indeed! The tood depending on what capabilities it knows about and what the computer allows, can not only scan engine codes but codes from other systems as well! Including ABS, Transmission and more! I ran into a snag on reading TPMS when I tested this tool on another vehicle. Lemur was notified and they are looking into a cause of why it couldn't read the codes from the TPMS systems of that vehicle. Might be that the computer didn't allow the tool access? Not sure. The tool once it finds issues will reveal the codes that are being reported. Then you can get a repair report. These diagnostic aids tell you what the code is and what are the most likely culprits that are causing it. Again use this as a diagnostic aid and not gospel for finding out the issue. This I feel is a nice feature! The tool can clear out the trouble codes. However I do wish that Lemur would tell you what state the car needs to be in to clear the codes. Like my vehicle has to be in the run position but engine off in order to clear the codes. Some cars need to be running. I think a safe bet here is key to run but engine off. The tool can check for smog rediness which for emissions is a definite must! If your vehicle supports it, the tool can check the status of the check engine light for parameters such as how long the light has been on and when the last time the light was reset. Again only if your computer supports it. The tool can decode a VIN and tell you where the car was made, what engine is in it, and all sorts of goodies. The tool makes an effort to figure out the VIN from the computer. However if it cant, then you can either manually enter it with a keyboard or if your car has a VIN barcode, you can take a picture of the VIN right in the app and it will fill in that blank for you! That is awesome! The live data tool is very good tool indeed! Depending on what you engine will allow to be read, you can see in real time what the engine is doing and help you narrow down what might be wrong! Best of all, a lot of the data from this tool like the Live Data, smog rediness, repair reports, etc can be exported out of the tool so if you need to analyze them on a computer or send to a friend that is more mechanically inclined, you can do so. A word of warning about the Live Data, it will only export out the PIDS you've selected and it only exports out data in a CSV (Comma Seperated Values) format useful in spreadsheets. It does not export out the pretty graphs ( I haven't found a way to export the graphs at least) that the tool generates. Would I personally consider this a professional tool? Possibly. Reasoning for my thinking is the mode 6 data/testing is useless to me as of this review. I noticed that some of the sensor PIDS are not even in the tool to be read or read in a certain way and should be if this is to be considered a professional tool. Case in point is the Cam and Crank sensors. Maybe this in in the mode 6 data however I do not know because again I can't read it and I cannot gain access to a TID/PID chart for this. Reason why reading the cam and crank sensors would be good is for a crank but no start condition. Even if we had a PID that would tell us that the cam and crank was in sync would help here. Without reading this data, this tool cannot help you with a crank but no start. At least on my vehicle which happens to be a 02 Jeep Liberty. However if you need a fairly inexpensive tool that is compact, fairly easy to use, updateable, IMHO very good support and can be used a a way to constantly monitor the vehicle (you can leave plugged in), this tool can definitly help with your vehicular woes. Maybe when the tool gets more updates, I will come back and update this review. If y'all are wondering if this has helped me with our vehicle? The answer is yes! I was able to get some live data and it is pointing to a few things that could be wrong with the vehicle. Once I get a clear day, I will get to cracking on this! Hope this helps someone.

This is S-L-O-W but it gets the job done. From the first year of ODB-II (my son's '95 Volvo 850) to modern vehicles this handy and low-cost device reads and clears all code I've needed it to and has paid for itself. As an automotive hobbyist I find this an essential tool that works well.

I bought this to help my son with some repairs on his Durango, and have used it on my Sierra and my wife’s Volvo. It has definitely helped to diagnose some issues and get to the bottom of the problem when a light comes up on the dashboard. If you enjoy working on your vehicles and nerding out on what’s happening in and around your vehicle and its computer and sensors, this is a worthwhile investment.

I couldn’t be happier with this OBD2 scanner. Setup was incredibly quick — just plug it in, connect via Bluetooth, and the app walks you through everything step-by-step. Within minutes I was reading codes, checking live data, and finally understanding what was actually going on with my vehicle instead of guessing. What really stands out is the detailed diagnostics. It doesn’t just give you a generic code — it explains the issue, possible causes, and even recommended fixes. The live data monitoring is super helpful for troubleshooting in real time, and clearing codes after repairs is simple. Build quality feels solid, the connection is stable, and I love that there are no subscription fees. It works flawlessly with my phone and has already saved me a trip (and hundreds of dollars) to the mechanic. If you own a car — especially an older one — this tool is a must-have. Highly recommended for both beginners and experienced DIYers.

Update 12/03/25. After several have complaint here and on other forums the company decided to revert this change they made and now you don’t have to open an account to use it. Thanks for all that helped to make this company change their stance. Update 05/24/25. They updated to version 8 a few days back which now asks for you to open a “free” account with them. This is just another ploy for an overpriced gadget ($89 today) to be able to data mine and sell to brokers and insurance companies who are paying big bucks to garner this information. To ad insult to injury they want your email to send a confirmation code. The email never arrived for 3 days and when it did it came after 1 hour of requesting the code. Problem Is you have to use it within 10 mins of them sending it to you. I plugged in the number less than 30 secs after getting the code it said it had been more than 10 Mins! This item has not been able to be used because of a flawed deployment of version 8. If you go To the Apple Store and look at their ratings you will see that people are complaining about this issue already. They claim the will not use your data. Yeah right! Even if you used a fake name and disposable email your VIN numbers are saved. They can be easily tied to You since now a days cars record EVEYTHING you do in your car (speed, how many miles/hours you drive a day, location etc). They should have an opt out to This data mining. I really hope they get a lawyer to destroy them In a lawsuit. I’m going ti write and see if they will reimburse me. Plenty of other devices similar to This one that cost 1/3 of price and don’t data mine. Years have passed and reading other reviews while this and other readers are not perfect, they give you the info you need for 75% less than blue driver without asking you to register or render the item you paid for useless. Revised 2016 I bought this [with my own money not a free on for a review] hoping I would not have to use my very expensive hand held ones anymore which are cumbersome and you always pretty much have to go to the computer to get the codes and search on the net to see what they mean, possible causes and possible fixes. I bought one on amazon similar to this one that was around $18 and had to buy a couple of apps for my phone [around 10 dollars for the apps] to be able to use it. It was OK but I wanted MORE information. I read amazon reviews and realized this was the Cadillac of them at this time [Jan 2016]. I got it in 2 days with Prime. I plugged it on my 3 vehicles and it gives us a plethora of information. We have since sold our hand held ones on craigslist since this thing works so good and gives you unbelievable amount of information. [I do have a couple of complaints, later in the review.] I have been looking for another used vehicle and this device has saved us thousands $$. Your phone is connected to the internet so it goes out and gets you a lot of extra info right away & also updates the device software if need be. It even gives you information about when was the last time someone ERASED ERROR CODES which is happening across the dealers & private sellers in the 40207 and 33186 zip codes more than you would have thought! [in DAYS:HRS:MINS and also miles]. Don't forget anyone can get a cheap code reader for less than 20 dollars and erase all codes! The serious codes that the vehicle computer reads will come back immediately if erased, others will take a day or 2 -or longer-of driving time to come back in. To late if you bought a vehicle from a private owner and it's in your name already. Its funny to see the face of people when I tell them, these are all the error codes that the vehicle is giving me, the possible causes [yes this thing does tell you that too!] and BTW someone erased the codes 3 days 22 hrs and 3 minutes ago! It will give you all recalls for the make and model has had from day one! You can ask the owner or dealer to make sure those have been addressed or not. Most will claim [dealers and private owners] that no one has erased the error codes. I say to them "well sir or madam, this is what YOUR vehicle computer is telling my device. It pretty much saying that someone came in here with a key and a code reader, plugged it in and erased the codes 3 days 22 hrs and 3 minutes ago!" When they finally fess up [not all of them do] I just ask them what were the codes that were erased [to see if it was something easy like they didn't close the fuel cap correctly or something serious like -which I got on several different vehicles without any lights on the dash-a catalytic converter, an O2 sensor or both, anti lock brake codes, steering angle sensors, low or high voltage power supply, tire pressure warning system codes, airbag malfunctions, etc]. This purchase has saved thousands on repairs on several vehicles I checked and would have bought!. Sellers were asking top dollar for these vehicles because they had “no lights on the dash” and they had done a cleaning detail on the vehicle! I even took a vehicle that I really liked to a dealership and paid for an inspection. They didn't get what I got on the code reader at first [or just didn't plug their code reader] but when I complained to the service manager, they hooked up their reader and got the same stuff [erased codes] and other malfunction codes that were not showing on the dash. BTW this device only tells you that codes were erased, it does not tell ou which ones. They refunded my inspection money because of their embarrassment. That right there paid for this device! I also have run in a couple of situations where the person selling the vehicle has advertised a higher model of the vehicle I was looking at to get more money out of it. These are vehicles in the 7k to 15k range I've been looking at [clean title only]. This has happened with private sellers who either buy the LXE [as an example] letters from ebay or a junk yard [I am guessing] and put the new letters claiming the vehicle is a higher level that it really is. The software on this device reads the vin number goes to the net and gets the EXACT model and make from the vehicle. You should see the face of people when I tell them this is a L model [the lower end one ] and not the LEX one! Some of you would say this is on the tittle, well…. Not always. I have a Honda Odyssey and the title does NOT say which model it is! I think everyone reading this knows there are lots of people who are buying vehicles at auction, cleaning them up and sell them for profit posing as regular owners. A vehicle fax can be $40/vehicle and gets expensive quick if you do several cars. [I like vehicle carfax over other because they give you a lot more information on regular service etc than their competitors]. In my area code and in the MIAMI area -which is were I have been also trying to buy a used vehicle- there are tons of people selling more than 10 vehicles a year [which are required by law to get a dealer license and do not]. When you ask them why is the vehicle not on their name, or why the have 4 vehicles for sale out of their house, or why was the title on the vehicles he/she's selling less than 3 weeks old the come with the story about them getting a better vehicle or sob storries. If you pry hard enough they'll tell you they are "wholesalers" but don't have the required licenses insurance etc and are less than reputable in the disclosure of their vehicles they're selling. Don't get me started on the habitual “private” sellers of salvage but repaired title vehicles! Use this device wisely and save yourself a lot of headaches or negotiate a better price on the used vehicle you are buying and also check your existing vehicles and telling your mechanic exactly what is going on. Be an informed consumer. I have two complaints about the device: 1- When looking this couple of months for a used vehicle in zip code areas 40207 and 33186, I usually start the vehicle with it plugged in, let it read all the codes, vin number etc, while the vehicle is warming up, then I drive the vehicle for about 15 to 20 mins to get more info on what the vehicle is doing while you drive it etc and hope that one of the erased codes pops up again. I have lost connection with my phone and the device several times while driving, where I have to stop and reconnect it and therefore lost all data that was being recorded. I thought it could be my phone connection via the Blue-tooth, so I downloaded the app on my wifes phone and the same thing happens! They are both newer iphone 6 and 6 +. Sellers are not to happy to go around and drive the vehicle again for 20 mins so I can record results again! 2-I have also had the device fall from the ODBII plug several times. This kind of sucks because you have to start the process all over again and lose all the data that was there before. I have checked about 20 vehicles in the last 3 months. I usually email myself the data while the app is running and they show the results from that email to the seller if there is something wrong since I haven't figured out how to save the data in the phone. I have resorted now to getting some blue tape and taping it around the plug and the device when its plugged in. Not something I'm happy about. Hope this helps some of you out there.
