About Mast: Commitment App Blocker
Odysseus knew he couldn't resist the Sirens, so he had himself tied to the mast. Mast does the same for your phone. Screen Time limits are easy to dismiss. Mast is different: you create commitments, scheduled blocks where your distracting apps lock, and you decide up front what it takes to get them back. Your apps don't just come back when time passes. They unlock when you act. HOW IT WORKS 1. Choose the apps that steal your time: TikTok, Instagram, games, anything. 2. Schedule your commitments: study sessions, work hours, mornings, evenings. 3. Pick your unlock policy, what it takes to earn your apps back: • Photo: snap a photo to prove you did it: gym clothes on, books open, bed made • Timer: run down a focus timer before anything unlocks • Mark done: apps stay locked until you check the task off • Just wait: or simply lock yourself out for a set time WHY IT WORKS Psychologists call it a Ulysses pact: a binding decision you make now, while you're clear-headed, that your weaker future self can't undo. Willpower fails in the moment, so Mast removes the moment. When the commitment starts, the ropes are already tied. There's no "remind me in 15 minutes" to tap through, and the only way out is the one you chose yourself. • Powerful blocking built on Apple's Screen Time technology • Flexible schedules for study, work, sleep or a full digital detox • See the hours you've won back If you have any ideas or questions, please email us at [email protected].
