On Samsung S7, I use the native recording app, Game Screen Recorder, or DU Recorder to record my games. Each has its perks. For the timer, I use a simple app called Floating Speedrun Timer. It can get in the way of your playing, so make sure its in a good spot before you start recording.

On Amazon Kindle, I use SmartPixel to record, upload to Facebook, download, and add a timer in a video editing software called ShotCut. I'm not sure if this specific game is on that device, though.

If you have a different way of recording and timing, please share!
