A salah tracker built around a passive NFC puck kept where you pray. At each call to prayer, distracting apps lock until you tap it, and they come back a few minutes later, so tapping and walking away earns nothing. Swift 6 on Apple's Screen Time APIs, with puck links signed with Ed25519 and checked offline.
