About Day Zero — Focus & Discipline
One day. No rewind. This app gives you one day only. When the day ends, it’s locked forever. Missed tasks become failed. Yesterday cannot be edited. No excuses. Just facts. How it works - Plan tasks for today - At midnight, the day closes automatically - Unfinished tasks are marked as failed - Completed tasks stay completed - Past days cannot be changed Every day leaves a permanent record. What you see - Daily, weekly, and monthly statistics - Real progress based on completed actions - Goals built from facts, not intentions - A ledger showing your actual behavior over time This is not a motivational app. It’s a system that reflects reality. Notifications Only two per day: - Fill your day - One hour before the day closes No reminders. No encouragement. No forgiveness. This app is for you if - You want truth, not comfort - You’re tired of rewriting the past - You want to see who you really are over time If you miss a day — it stays missed.
