75 days. 75 squares. Your rules. 75 Soft turns the 75 Soft Challenge into something you can see: a grid of 75 squares that fills a little every day you keep your rules. HOW IT WORKS • Pick your 75: Soft, Medium, Strict or your own rules • Check the rules you kept today • Hold to fill today's square, striped in the colors of the rules you kept, or with your photo of the day • Missed a day? It stays quiet. No restart. Tomorrow is a fresh square MADE FOR THE SOFT VERSION • Partial days count: keep 3 of 5 and today still fills • Water in small steps, any book counts, a rest day is fine • One gentle reminder a day, only when your square is still empty SHARE THE GOOD PARTS • Your rules card, the list people save before they start • Day 20/75 stamps for Stories and TikTok • Milestones at Day 7, 21 and 50 • Day 75: your whole 75 on one poster SOFT PLUS • Your photo inside every square • Fill in a quiet day, twice a month • Day 75 poster in full quality and a 15-second film of your 75 filling up Your days stay on your phone and are included in your phone's backup.
