Deny locks the apps that waste your time — and puts a friend in charge of the key. Most screen-time apps fail for one reason: the moment you want back in, you just tap "ignore limit." Deny removes that escape hatch. Block your most distracting apps, and when you want to unlock them, you have to ask a friend to approve it. HOW IT WORKS • Build block groups — pick the apps and sites to lock, on a schedule or a daily time limit. • Stay locked. Blocked apps are shielded by iOS, so there's no sneaking past them. • Allow temporary unlocks — give yourself a set number of minutes, with a live countdown showing exactly when apps re-lock. • Bring in friends. Connect with an invite code, then ask a friend for screen time. They approve or deny — you stay accountable. • See each other's progress and keep one another honest. WHY DENY • Friends make it stick. Accountability beats willpower. • Honest by design — no one-tap "ignore." • Private. Your data is yours; we never sell it or use it for ads. Deny uses Apple's Screen Time (Family Controls) features to block apps on your own device. Take back your attention — together.
