Strict habit tracker & app blocker. Miss a day? Auto-restart. Build true focus.
About Restart21: Habit & App Blocker
🔥 THE STRICTEST HABIT TRACKER & REAL-TIME APP BLOCKER
Tired of soft habit trackers that let you skip days without consequences? ReStart21 is a hardcore accountability system, powerful habit builder, and unbeatable app blocker for people serious about change.
Miss a day → streak resets to Day 1. No excuses. No shortcuts. True discipline.
🆕 LIVE OVERLAY BLOCKER (Task-Linked)
This is what makes ReStart21 unlike any other habit app.
When your task is active and you try to open a blocked app like Instagram:
→ A floating overlay appears instantly ON TOP of the app
→ Shows your live focus timer — how long you have stayed strong
→ An immediate LOCK button is right there — one tap and the app closes
→ You cannot scroll past it. It confronts you in the moment.
Not a notification. A real-time intervention the instant you reach for a distraction.
🎯 CHOOSE YOUR DURATION
21, 30, 60, 90, 100, 180, 360, or 720 Days.
12 Default Templates: Quit Smoking · No Alcohol · Quit Adult Content · No Social Media · No F&O Trading · Daily Exercise · 10K Steps · No Junk Food · No Sugar · Read 10 Pages · Deep Work 2 Hours · Plan Tomorrow Tonight
🚫 SMART TASK-LINKED APP BLOCKER
Link any task to specific apps. The moment your task starts:
✓ Instagram, YouTube, trading apps — automatically blocked
✓ Floating overlay fires the instant a blocked app is opened
✓ Live focus timer on the overlay — makes it harder to quit mid-session
✓ Blocking ends automatically when your task ends
The only habit app where your phone enforces your commitment, not just records it.
🛑 STANDALONE BLOCKING (3-STRIKE RULE)
Lock your phone instantly, outside of any task:
• Force Lock — standard blocking for immediate focus
• Auto-Lock (3 Strikes) — 2 warnings, then screen locks automatically
• Strict Lock Mode — zero access, no bypass, unbreakable
⏱️ LIVE TIMER & FULL-SCREEN ALERTS
• Live streak timer in your notification panel — the longer it runs, the harder it is to stop
• Full-screen alerts when habits start or end — impossible to ignore
• Overlay focus timer appears on top of blocked apps during active tasks
💎 GAMIFIED POINT SYSTEM
• Earn points completing tasks and daily check-ins
• Watch reward ads to earn more points
• Unblocking an app early costs heavy points — friction that stops impulsive breaks
📊 CALENDAR, WIDGETS & CERTIFICATES
• Full history calendar showing every completed and missed day
• Home screen widgets with your live streak timer
• Shareable achievement certificates when you complete a goal
✅ WHO IS RESTART21 FOR?
→ Students — JEE, NEET, UPSC prep needing a real study enforcer
→ Traders — Block F&O apps, stop over-trading during off-hours
→ Addiction Recovery — Quit smoking, drinking, or adult content
→ Dopamine Detox — Monk Mode, social media detox, digital minimalism
