Mobile games usually get a bad rep as they’re usually asset flips and/or MTX-ridden and/or ad-filled, etc., and I’m sure this is actually the case for most games on the app/play store. But are there any ones that are actually good, maybe just something to pass the time with?
Ace Attorney I believe had a very good mobile port.
One I’ve been addicted to, and have spent no money on, is Zenless Zone Zero. Gacha game with action-style combat using dodges, parries, and flashy effects. In some ways a cool demonstration of what phones can render now. Very much depends on what your gacha/FOMO resistance is.
