Hello,
I'm not sure if someone from this forum found this app useful but just in case. I recently published EcoShifter Pro with a lot of new features and improvements:
* Completely redesigned UI (cleaner, nicer and easier).
* Android 4.x-friendly app but still compatible with Android 2 and 3.
* Support tablets, 7 and 10 inch.
* Acceleration/deceleration indicator with arrows
* Full screen mode when connected.
* More stable and accurate
Check it out on Google Play searching for "EcoShifter Pro" and maybe give it a go.
Thanks!
