Ratings and reviews

After the update It will not connect to my device anymore. I did the troubleshooting list that the support at holle told me to do and it is still not connecting. the app just loads and takes ages. Usually when it cant find the device it will notify however it just sits on the screen loading. when it was working the app and the device were great. hopefully they will fix it

Doesn't work on Motorola phone or Samsung tablet. Started not connecting to device, engineering worked on it, now connects but crashes when trying to auto calibrate tired size. Terrible communication, no email when they have a fix to try. Phone rep said 'app is buggy'. I won't trust it off road for other features used for winching, etc. Holley did step up to send wired device. Phone help have long hold, but guys seem interested in helping far more than engineering did. To bad, interface is cool!

Why do I have to unplug and plug in flashcal+ device every time I open the app? Everything seems to be working but each time I want to open the app and watch gauges or make changes the app doesn't see the device and needs to be unplugged and plugged back in.
