ZBD is a generally nice app for stacking sats together through playing vaious games. Many people using in report about 1 million sats a year. https://zbd.link/hcHi/invite?af_sub1=SMPP97&deep_link_value=fwb_two_for_two

Ember literally lets you earn passively, only needing to tap a button once a day. Only catch is, you need to "wash" your sats through gambling before withdrawing - least risky game being Plinko with a max loss off 30% bet.

Wombat works a bit like ZBD and Mistplay in a sense; you earn coins that you put in the weekly drop of $1000, and you can change what cyrptocurrency you're wanting from. Not all cryptocurrencies are available though, and this app doesn't payout too much. Also gives NFTs you can keep or use in Wombat Dungeons. https://go.getwombat.io/k4gq

Speed Wallet is primarily a wallet, but also sports ways to stack sats. It's also a place to withdraw from ZBD, if you don't already have one.
