On Samsung S7, I use Game Screen Recorder to record my games. 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.
Web Resources On Google Chrome, if you play on a computer, you can record using Fraps and use LiveSplit to time. Fraps: http://www.fraps.com/download.php LiveSplit: https://livesplit.github.io/downloads/
What do you use? Your suggestions will help new runners!
