Waste of money and time. The last update to the software version was 5 YRS AGO! ### 1/5 — Can’t even connect *2023-08-08, version 1.0.24* I’ve tried so many times… with different methods.. still can’t connect. Total garbage ### 1/5 — New iOS 15 *2023-01-02, version 1.0.24* Any updates coming out? $300 for a dongle that doesn’t work properly. ### 1/5 — No longer Supported *2022-11-05, version 1.0.24* This product is no longer supported by APR. A total waste of money and time. Avoid buying the dongle. ### 1/5 — Warning, the apr dongle will not work if you bought it second hand. *2021-09-17, version 1.0.24* Just to let anyone know who’s looking to buy an APR dongle be sure to get it brand new! A second hand one will not work for your car if it’s already been registered to another vehicle. Lesson learned for a newbie 😢. Hey APR maybe you should charge a small fee to unlock these for people that have been duped 🤣 ### 1/5 — Didn’t work *2021-03-07, version 1.0.24* Just needs updating so it works again. Come on APR get it done. ### 3/5 — Crashes and disconnects *2020-07-22, version 1.0.24* I can’t seem to keep the dongle connected. If an app switches to foreground and I flip back to the APR app I can’t get it to reconnect to the car unless I turn off the car and unplug the dongle etc.. lots of trouble on the latest update with that. Also viewing logs causes lots of crashes and I can’t seem to load some historical logs in demo mode without crashing constantly. ### 3/5 — Mine doesn’t work *2018-11-29, version 1.0.23* I have it on my new RS7 and for some reason can’t get it to sink with my phone. Heard something about the app needs updating but who knows ... ### 2/5 — Not impressed *2018-11-26, version 1.0.23* Keeps failing to work. Connects to dongle but won’t let me put code in just says this car does not have.... ### 5/5 — Great add on *2018-04-07, version 1.0.22* I have had mobile for 2/3 years. Its awesome for clearing fault codes and for diagnostics. I’m able to run the car, data log and send outputs to my shop from anywhere. Only issues I’ve had are related to have a few app updates that have impacted functionality. That said, the APR team has been super responsive and they have done a killer job with bug fixes and support. ## Frequently asked questions about APR Mobile ### What does APR Mobile do?
