Needed to program new keys for my 2017 Jeep Compass with remote start. WORKED GREAT.. I had set-up issues I resolved by restarting phone and connecting Bluetooth more carefully following instructions closer. Worked very well using instructions I found on U Tube for a Jeep Cherokee. Worked exactly as described. Got 2 new keys with remote start, I thought that would be the hardest part. But it all came together like magic. $75 for 2 new keys a great value. The $25 for this app is a bargain.👍👍

This app does everything and more than you could ever want in a scan tool. Extremely capable piece of software that could be a little intimidating to an average Joe like myself. They are super responsive if you need to contact them and go beyond expectations when trying to troubleshoot! Overall, amazing app and would recommend as an addition to any mechanic tool box!

Most user friendly programmer - a little buggy I would easily give this app 5 stars if it weren't so buggy. Had problems communicating with ECM using recommended iCar module. Communication tests fail. I have to delete app and reinstall after each use, then re-pair module. A little frustrating, but when working this app is absolutely amazing!! Adding presets such as economy, power, etc. would put the icing on the cake. Thank you to the developer for their work on this!
