About this app
Winter arc with your crew. Pick your rules and check in for 90 days.
Read full description
90 days of doing what you said you’d do. Pick your rules, sign a contract with yourself and check in every day until the summit. Alone, or with a crew of up to 8 friends. PICK YOUR RULES Wake up before 6. Train 4 times a week. No alcohol. No doomscrolling in bed. Choose a few things to do or to avoid, give each one a time if you like, and group them into areas like Stronger, Healthier or Focused. SIGN A CONTRACT WITH YOURSELF Your rules turn into a short letter from you to you, and you sign it with your finger. Nobody else ever reads it, so be honest. PICK HOW HARD IT GETS Warm-up: one rule can slip each day. Standard: hit all your rules, with one free miss a week. Hard: one miss ends your streak. Monk mode: miss once and you’re back to day 1. Every weight comes with 3 sick days. You can switch until the end of day 3. After that, no take-backs. SHOW UP EVERY DAY Each rule can remind you at its own time. Missed a deadline by a few minutes? You get a grace hour. Your day ends at 3:00 am, not midnight, so the late gym session still counts. Forgot to tick something? Fix yesterday the next morning. DO IT WITH YOUR CREW Crews are invite only: up to 8 people, each with their own rules. See who showed up today, cheer them on, nudge the ones who haven’t, and talk it out in the crew chat. Your crew sees how many of your rules you’ve done, never what they are. Report and block are built in. SEE EVERY DAY OF YOUR CLIMB Your arc is drawn as a climb: Camp 1 on day 30, Camp 2 on day 60, the summit on day 90. The calendar, week by week, patterns and each rule’s history show where you held and where you slipped. Bad days stay on the map, and sick days never count as a miss. YOUR RULES STAY ON YOUR PHONE Rules, check-ins and your contract live on your phone and in your own Google backup. We never see them. Going solo needs no account; crews use Sign in with Google. No ads, and no analytics on your check-ins or rules. YOUR FIRST 3 DAYS ARE FREE Start free and try the whole app for 3 days, with no payment details. After that, the arc is one in-app purchase: 90 days, paid once, and nothing renews or is charged automatically. Until you buy it, Today, Progress and Crew wait, and so does your arc: you pick up at day 4 when you do. Rough start? Start over from day 1, free, up to 3 times until day 30; a start over past the free ones is a new purchase of the arc. After day 90 you can run it back with another arc (a new purchase), start fresh, or take a break.
