marcus.

You open an app to send one message and spend forty minutes in its feed. Marcus uses Apple Screen Time to block the app. Rules can respond to your schedule, location, sleep and workouts. Friends can see whether you kept the rule, which makes it harder to turn the blocker off without saying so.

free

the blocker and all rule types are free, with no ads.

native

Marcus uses Screen Time to block apps and can use HealthKit, location or workouts to change when a rule runs. usage stats stay on the phone.

social

friends see streaks and daily totals without seeing which apps you opened.

rules can use time, place, sleep or workouts.

Fixed hours do not suit every day. Marcus can also start or end a rule based on place, sleep or a workout. Allow-lists keep needed apps open, strict mode limits changes and block now starts a session at once.

free, with an optional tip.

I built Marcus after refusing to pay another subscription to block apps. The blocker and all rule types are free, with no ads or yearly fee. People who want to support the app can leave a tip in Settings.
