New: your 75 is a grid. Keep your soft rules, hold to fill today's square and watch 75 squares fill with your days. Missed a day? No restart.
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. No account needed.
Soft Plus is offered yearly (with a free trial for eligible new subscribers) or monthly. It renews automatically unless canceled at least 24 hours before the end of the period. Manage or cancel anytime in your account settings.

75 Soft 8.0: your jar is now a 75-square grid. Every kept day fills a square, striped with the rules you kept or holding your photo. Your past days moved over automatically. New: rules card, Day stamps and milestones.
