OBD JScan

Seemed the only app that would actually identify an odd communication error initiated after a flat battery that pointed to bad data from the ABS module suggesting it required replacement. Prevented forward collision avoidance & cruise from working. The app allowed me to clear the fault & return all back to normal when even my full scan tool seemed useless on the jeep(2020 Summit). Excellent app A+++

JScan is an absolutely fantastic tool for troubleshooting issues, clearing codes and making configuration changes like speedo correction. Easy to use, and great support from the team behind it!

If you own a jeep you need this app best money spent on a app in a long time Packed full of useful features and great information

I have tried a number of OBD apps across a number of vehicles. I use the Foseal adapter and while it’s not in the recommended list for this App it works great. This app is significantly better than any others I have used on my Jeep Documentation is a another bonus

Awesome app! cleared the TPMS light, adjusted the tyre size so the speedometer reads accurately which also means the transmission shifts correctly and that is just scratching the surface of what this app can do!

Great

If you have a Jeep, Dodge or Chrysler vehicle, this is an amazingly useful app. You can do stuff you’d otherwise get shafted at a dealership to have done. Unfortunately, the app crashes often, particularly when using the live data features. I haven’t been able to have it running for more than 20 minutes before it crashes. The user interface is inconsistent - sometimes when rotating the phone 90 degrees and back, everything is all wonky, and there is not nearly enough help text. For example, some adaptations say you must have the key at a certain position but others don’t say anything and require you to try the adaption with different key positions to find the one that works. It reads codes very slowly compared to other apps (e.g. Car Scanner) even when using the same Bluetooth OBD scanner. Once the stability, performance and user experience issues are sorted, this is an easy 5. If the app weren’t so uniquely useful my rating now would be a 3, but due to its excellent feature set it gets a 4 from me.

App is quite buggy, appears to be a low priority for development team. Experienced a bug where unexpected app behaviour caused undesired vehicle behaviour and little effort was made to resolve before support simply stopped responding.

Yes

This is the first app that has allowed me to monitor my transmission oil temp. Awesome.
