## What is 75 Day Challenge?

A 75-day habit challenge you can actually finish. Pick Strict, Soft, Medium, or Custom. Check off the day. Take a private photo. Lock it in.

WHAT YOU GET
• Daily checklist for workouts, water, reading, diet, and a progress photo
• Strict, Soft, Medium, or your own rules
• A 75-day grid that shows locked, missed, and days still ahead
• Private photos on this iPhone. Compare any two days.
• A Day Card you can share when you lock the day
• Widgets for the Home Screen and Lock Screen
• Reminders you control

HOW IT WORKS
1. Choose a preset and a start date
2. Do the work
3. Lock the day before midnight
On Strict, a missed day restarts the attempt. Soft and Medium keep going. History and photos stay.

Unlock with a 3-day free trial, then a weekly plan, or pay once for lifetime.
