The 75 day challenge made for women. Pick your level: gentle reset or full discipline, and build the routine to become the best version of yourself. Track every habit with proof photos, watch your streak grow, and see your transformation day by day. — CHOOSE YOUR HARD — Some Examples: • 75 Days: made for women, by women • 75 Strict: the original, no compromises • 75 Medium: disciplined, but realistic for those with very busy lives • 75 Soft: gentle reset, sustainable habits • Better Me: habits that actually stick — DAILY MISSIONS — Workouts, water, reading, clean eating, no alcohol, daily progress photo: each challenge ships with smart defaults you can fully customise. Add your own habits. Swap the ones that aren't yours. — PROOF, NOT PROMISES — Tap a habit to mark it done and capture a quick proof photo. Your camera roll becomes a visual streak: receipts you can scroll back through on day 75. — BEAUTIFUL HOME SCREEN — Sticky-note widget pinned to your lock screen and home screen see today's tasks at a glance, tap to check them off without opening the app. Pair it with our custom wallpapers for a phone that actually feels like yours. — PROGRESS PHOTOS — A private, time-lapsed gallery of your transformation. Day 1 to Day 75, side by side. — SOFT, FEMININE, FOCUSED — No drill-sergeant energy. Just a calm, beautiful space to show up for yourself daily built with beautiful typography, sticky-note tasks, and pastel polaroids. — BUILT TO LAST 75 DAYS — Streak protection, daily reminders, calendar view, missed-day recovery designed so the challenge ends with you stronger, not burnt out. — MAKE IT YOURS — Pick a profile photo for your Today screen. Generate a home-screen wallpaper from a curated gradient library, our editorial photos, or your own camera roll — choose where the text sits, toggle a soft blur, and overlay your daily tasks if you want them visible from the lock screen. Match your widget background to your aesthetic with light or dark text. — REMINDERS THAT DON'T NAG — Three soft check-ins a day: morning, midday, evening. Edit the times, write a custom message, or turn slots off. Notifications are generated on your device — never sent through a server. — FRIENDS — Add your girlies, see their progress, and cheer each other through the 75. This isn't another habit app. It's a 75-day commitment to the girl you're becoming.
