Day Tracker, Streak & Photos
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
75 days. One checklist. Zero excuses. Hard, Soft or Custom mode — with Apple Watch, widgets and private progress photos. One-time purchase, no subscription.
Take on the 75-day challenge that changes everything. One daily checklist. One streak. Zero excuses.
CHOOSE YOUR MODE
- Hard Mode — two workouts, clean diet, no alcohol, a gallon of water, 10 pages of reading, and a daily progress photo. Miss one task and you restart at Day 1.
- Soft Mode — the sustainable version: one workout, three liters of water, reading, and balance.
- Custom Mode — build your own 75-day discipline challenge from a task library.
TRACK THE ONLY THING THAT MATTERS
Your day. A brutal, beautiful checklist: tap, complete, protect the streak. A 75-day grid shows every win and every miss. Your history of attempts stays — because restarting is part of the game.
SEE YOURSELF CHANGE
A daily progress photo, stored privately on your device only, with a Day 1 vs. today comparison slider. No account. No cloud. No one sees your photos but you.
BUILT FOR COMMITMENT
- Apple Watch app: check off tasks and log water from your wrist
- Widgets and Live Activity keep the countdown in sight
- Smart reminders before midnight so a busy day never costs you the streak
- Works fully offline — your data never leaves your phone
ONE-TIME PURCHASE. NO SUBSCRIPTION.
