The GameOnan app was announced by Amazon in November for recording short, shareable clips from your favorite mobile games. Initially, this app was only available on Android. But you can download GameOn on iOS as well if you own an iPhone or iPad and live in the US.
This app allows you to capture clips that come in anywhere between 30 seconds to five minutes in length. Edit any videos you capture and add live commentary is also possible using this app. You can even use it to record your reactions to something that happened in-game. GameOn currently works with more than 1,000 mobile games, including perennial favorites like PUBG Mobile and Crossy Road 2, in addition to more recent hits like Final Fantasy Brave Exvius.
