The App Store's strength for two players is polish — premium co-op stories and games that feel hand-finished. These are the iPhone picks we'd install first.
The showpieces
Sky: Children of the Light is the game to show someone what mobile co-op can be — luminous, gentle and made for two. Human: Fall Flat brings proper console-grade physics comedy to the phone.
The premium puzzle
The Past Within is a one-time purchase that buys an evening (or three) of genuine two-player mystery — the rare game with no ads, no energy bars, just the puzzle and the two of you.
Mixed household?
If one of you is on Android, nearly everything here still works — the crossplay guide explains what to check. The Android list covers the other side of the fence, and the ranked top picks work everywhere.
