Fifteen - Hardcore Lock
No Snooze. No Early Unlock.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Most app limits ask nicely. One tap on "ignore" and the limit is gone. That back door is exactly why they don't work.
Fifteen has no back door.
Choose your apps. Choose your time, from 15 minutes to 30 days. The moment you confirm, the decision leaves your hands until the timer reaches zero. There is no unlock button in this app, because we never built one. No snooze. No "ignore for today." No "just five more minutes." Restarting your phone won't help. Opening Fifteen and begging changes nothing.
You made the call once, while you were still thinking clearly. Fifteen exists to make sure that version of you wins.
[THREE WAYS TO LOCK]
- NOW: the irreversible one
Pick your distractions, set the clock, commit. Once it starts, it runs to zero. Nothing you do shortens it.
- SCHEDULE: the one that shows up on its own
Recurring windows you set in advance, while you were still being honest with yourself: weekdays, work hours, overnight, every other week. Your blocks arrive whether you remember them or not.
- AI: the one that sees it coming
Fifteen learns the times of day you habitually reach for the apps you are trying to quit. Minutes before your usual moment of weakness, it warns you and offers you the lock. Accept, and it is as final as any other lock. It never locks you without your word, and the learning never leaves your device.
[CORE PROTOCOLS]
- TERMINAL INTERFACE
Minimalist, high-contrast, distraction-free. No rounded corners. No dopamine colors. Pure utility.
- REALITY CHECK
Open a blocked app and you get a reality check instead. "Touch grass." "Don't be weak." "Embrace the void."
- NO ESCAPE, NOT A HOSTAGE
The countdown is untouchable. The rest of the app is not: step out of the timer to set up tomorrow's schedule, then step back in. You simply cannot shorten today.
- PRIVACY FIRST
Everything stays on your device. We do not track your activity. Your discipline is your own business.
[PRICING]
Three free sessions in every mode. Then one payment, forever. No subscription. No ads. No upsells.
[REQUIREMENTS]
Fifteen enforces blocks through Apple's Screen Time API and asks for Screen Time access on first launch. iOS keeps your usage private even from us.
[PHILOSOPHY]
Discipline is freedom.
The phone can wait.
You are stronger than this.
ARE YOU READY TO COMMIT?
Two new ways to lock, and neither one waits for your willpower.
SCHEDULE — Recurring blocks that fire on their own. Pick the days, the hours, even every-other-week. Overnight windows included.
AI — On-device only. Fifteen learns when you habitually reach for the apps you are trying to quit, then warns you before that moment arrives and offers you the lock. It never locks you without your say-so, and your usage data never leaves your phone.
ALSO IN THIS RELEASE
- A running lock no longer takes over the whole app. The countdown stays, but you can step out to manage Schedule and AI, then step back in.
- Larger, easier controls throughout, especially the time pickers.
- Every mode now comes with three free sessions before Pro.
- Many fixes to blocking accuracy, trial counting and purchase restoring.
