It opens fine on my old iPhone 13… ### 2/5 — Ehhh *2025-09-04, version 2.8.7* It works but can’t figure out the obd parts ### 4/5 — Great and very detailed *2025-07-10, version 2.8.4* But the app needs more frequent updates and optimizations with realtime updates ### 1/5 — Will not connect with recommended Panlong OBD2 scanner. *2025-02-17* This app simply goes through an endless loop of trying to connect to the recommended scanner. Even bought a second scanner in case that was it but this app still does not work. But I can use another OBD2 software product which works just fine. So it isn’t my hardware. It is the YMOBD software that does not work. ### 1/5 — Bluetooth *2025-01-30, version 2.8.0* Keeps disconnecting from Bluetooth please fix the problem ### 1/5 — Bad app，force to get location *2025-01-14, version 2.8.0* Always want to get location and need to register，it's a bad app. ### 2/5 — Works fine but requires location services *2024-11-17, version 2.7.9* App works fine but prompts asking for locations services every 10 seconds with no option to deny then jumps to settings. Very annoying, there is no reason it would require my location. ### 1/5 — Why do you require location services to work? *2024-10-27, version 2.7.7* All I want is a OBD-II scanner but you require I run this software to use it. Why do you require my location in order to work? Invasion of privacy. Returning the dongle and removing the app. ### 1/5 — Need to buy high end *2024-10-01, version 2.7.7* Bought this and have to buy something else like battery monitor ### 1/5 — Update asap *2024-09-27* Does not work on iOS 18 ### 1/5 — Pin? *2024-09-18, version 2.7.7* What’s my pin tho? I just got it ### 2/5 — 数据错误 *2024-09-15, version 2.7.7* 氧传感器 未就绪读成已就绪 ## Most critical reviews (10 lowest-rated) ### 1/5 — Not working *2026-07-25, version 3.0.0* Will not work on my newer iPhone ### 1/5 — Scam *2026-03-29, version 2.9.3* App works great. I purchased the battery monitor add on awhile ago, and it worked fine. Now when I log in to use that, it is trying to make me pay again and the contact section doesn’t work… ### 1/5 — Personal Info *2026-03-06, version 2.9.3* I try to used this app and it wouldn’t unless I give my personal information for them to share and it’s unnecessary to look the car computer. Returning ### 1/5 — Don’t bother *2026-02-28, version 2.9.3* I tried everything the app suggests as well as reading other reviews. It doesn’t connect at all. I’ve tried everything. Too good to be true. Great idea terrible product. ### 1/5 — Junk *2025-10-18, version 2.8.7* Just purchased an obd2 reader that is supposed to work with this software and it is complete garbage. Says my Bluetooth and locations need to be turned on and I have googled them off and on countless times. The device is powered on but software doesn’t read it at all. ### 1/5 — No transmission temperature *2025-10-09, version 2.8.7* Doesn’t show or have transmission temperature reading. ### 1/5 — Why need the location service? *2025-09-15, version 2.8.7* Why need to turn on the location service? I just want to use the OBD feature only ### 1/5 — Please update *2025-08-01, version 2.8.6* Please remove the need to add model make and year. Takes too long sometimes when we want to quickly scan a new car ### 1/5 — L for seat *2025-07-07, version 2.8.3* Doesn’t work on seat Ibiza 1.4 ### 1/5 — No Jeep Liberty option *2025-03-07, version 2.8.2* Jeep Liberty doesnt come up as a model that can be selected. Strange ## Most praised reviews (10 highest-rated) ### 5/5 — Amazing *2026-02-19, version 2.9.3* This dongle is perfect I fixed 3 cars with it. Amazing. Must have. Since you have a phone you can use it. No need for a big extra device. Please get on you will be happy. Amazon sells the dongle ### 5/5 — Decent OBD app *2025-11-27, version 2.9.0* Works well with my Toyota. I keep it connected to my truck so whenever I feel there's an issue, I can pull up the app on my phone a check into it. It's been very helpful so far. ### 5/5 — Well made *2025-10-24, version 2.8.7* Absolutely accurate and it also has a ton of functions love it. I’ve been using this product for about a year now and have never had an issue ### 5/5 — Works properly enough *2025-07-14, version 2.8.5* Can monitor live feed data like trims, reset codes, graph the values for o2 sensors. Really useful. Haven’t had an issue yet and been using this for a year. ### 5/5 — All in one place *2025-03-03* Love this app ! Everything you need to know about your vehicle! ### 5/5 — Good *2024-11-26, version 2.7.9* Very Good For Human ### 5/5 — Works well *2024-10-28, version 2.7.7* Very pleased with this. Very easy to connect to the corresponding Bluetooth OBD2 scanner. So much better than the wired scanner I used up to now. I haven’t tested all the features, but it does everything I need. Easy to read the data. Nice graphics. You enter your car model and it customises for that. ### 5/5 — Works perfectly *2024-07-23, version 2.6.9* Great little piece of equipment for the price, works every time without fail for me. Much better than the wired digital ones I have come across on the market. Highly recommended Only thing is I can’t seem to figure out how to purchase the extra features available?? ### 5/5 — Very pleased *2024-06-19, version 2.6.9* Easy to get App up and running. Took just a few minutes for OBD reader to initialize, perhaps 3 minutes at most. Reader and app quickly found the faults I was chasing. I am not a shill, but we are buying one of these readers to keep in all of our vehicles’ gloveboxes. ### 5/5 — Great App, more than I expected. *2024-01-25, version 2.6.0* Got the dongle at Temu for under $5.00, and this App for free. It’s been very helpful, easy to use. I had a little problem with the initial pairing but it was related to the new dongle not making a good connection. I had to push it hard the first few times. Now it’s no longer having that issue. The app provides a lot of helpful diagnostics information, even in realtime. Years ago I bought a $100 dongle called Automatic, which only provided DTCs. Then they decided to discontinue it, and would no longer worked. The only choice was to subscribe to their service. No way. So I didn’t have a dongle until now. And this dongle-app team it’s much better than the toy I used to have. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
