Short answer: No app pays out more than another by design. What varies is which RTP version of a game each casino runs, and you can check that in the game's help screen.
What payout percentage means
RTP is the share of all stakes a game is built to return over millions of plays. A 96% slot keeps 4% on average. It does not change between an app, a mobile site and a desktop.
