About
75 days. One list a day. No excuses.
Constant turns the 75-day challenge into a simple daily checklist. Choose your level, check off what you did, and watch the days add up.
CHOOSE YOUR LEVEL
• Strict: two 45-minute workouts (one outdoors), a strict diet, no alcohol, 3.8 L of water, 10 pages of non-fiction and a progress photo. Miss a day and you start again from day 1.
• Medium: one workout plus a walk, a diet with one cheat meal a week, no alcohol, 3 L of water, 10 pages.
• Soft: one workout, eat well, alcohol only when out with friends, 3 L of water, 10 pages. A missed day is marked, and you keep going.
• Custom: build your own list (no sugar, no social media, cold shower, your own rule…), 75 or 100 days.
You can change level along the way: your day count is kept.
EVERY DAY
• Check off your tasks in one tap.
• Log water with +250 / +500 ml (or ounces).
• Forgot to check yesterday? You have until noon to catch up.
• An evening reminder lists what is left, only when something is left.
SEE YOUR PROGRESS
• A 75-day calendar: done, missed, today.
• Daily progress photo with your last photo as a see-through overlay, so every shot lines up.
• Before / after slider and photo gallery.
• Your stats: days done, best attempt, workouts, liters, pages.
• A free 9:16 share card: your checked-off list of the day, ready for your TikTok or Instagram story.
APPLE HEALTH
Workouts, exercise minutes, steps and water from Apple Health can check off your tasks automatically. Water you add in Constant is saved to Apple Health.
