Vow turns focus into something you can keep. Most blockers nag, gamify, or lock you into a monthly subscription. Vow is calmer - and it's yours for one price, forever. Choose a phase (Deep Work, Family time, Exercise, Sleep, or your own) and Vow quietly blocks the apps that pull you away, backed by Apple's real Screen Time engine. A PHASE, NOT A TIMER Each phase is its own world: its own blocked apps, its own schedule, its own mood. Start one with a tap, an NFC sticker, or a set time - and stay present until you choose to return. A RITUAL THAT HOLDS Tap a cheap NFC sticker to begin or end a phase, even with the app closed. Link an Apple Focus so notifications truly fall silent across your iPhone, iPad, and Mac. Vow can make a phase harder to quit when you want it to - but there is always an honest way out. CALM BY DESIGN No streaks. No points. No guilt. Just a quiet interface, a living backdrop for each phase, and a promise you made to yourself. PRIVATE BY DEFAULT No account. No servers. No tracking. Your phases and app choices stay on your device - Vow never even sees which apps you block. ONE PRICE, NO SUBSCRIPTION Start free with one phase. Unlock unlimited phases, every world, automatic schedules, and the activity gate with a single Lifetime purchase. Buy once. Keep it forever. WHO VOW IS FOR - Deep workers and students who need real, unbreakable focus - Families protecting time that phones keep stealing - Anyone tired of paying a subscription to use their own attention - People who want screen-time tools that respect their privacy Keep your word. Vow. ——— PAYMENT, TERMS & PRIVACY Vow Lifetime is a one-time purchase - no subscription, no renewals, no recurring charges. Family Sharing included.
