I’ve spent my spare time during the last couple of weeks starting the development of an Android version of the TKController App. I’m targeting it to run on any device running API 16 or higher (Jelly Bean). I only have a single real device to test and develop it on (Samsung S5) and so far development is progressing well.
I’m not sure what the timescales will be to release as this is very much a hobby app and work and other commitments will mean that the amount of time I can devote to it will vary.
The Android App will have pretty much the same functionality as the iOS App. The two apps will also share the device data so as new device support is added or amended then the apps on both platforms will update.
