Your main character era starts today. Main Arc turns the Winter Arc trend into a plan you can actually keep: pick 3 daily rules, keep them every day until New Year (or for 30, 66 or 100 days), and watch every kept day light up your arc. HOW IT WORKS β€’ Pick an arc: Winter Arc, Glow-Up, Gym Arc, Monk Mode, Study Arc, Sober Arc, Money Arc, Morning Arc, Diet Arc β€” or write your own β€’ Start with ready-made rules and change them any way you like β€’ Tick today's rules β€” when all are done, the day counts β€’ Forgot to tick? Fix yesterday until midnight β€’ Shields save your streak when life happens β€” earn one every 7 kept days β€’ 7 ranks you keep for good: Rookie, Committed, Focused, Unstoppable, Elite, Main Character, Legend ALWAYS IN VIEW β€’ Lock Screen countdown to midnight β€” tick rules without opening the app β€’ Home Screen widgets with tick buttons, your arc and every day of it β€’ One evening nudge, only if today isn't done SHOW YOUR PROGRESS β€’ Story cards for Instagram and TikTok β€’ Recap video: your arc filling up, day by day β€’ A progress photo a day, turned into a before-and-after time-lapse MAIN ARC PRO Free includes an arc with up to 3 rules, widgets, the Lock Screen countdown, shields, ranks and story cards. Pro adds up to 5 rules, rules that tick themselves from Apple Health (steps, workouts, sleep and mindful minutes), progress photos with a time-lapse and the recap video β€” as a monthly plan or a one-time purchase. The monthly plan renews automatically unless cancelled at least 24 hours before the end of the period; manage it in your Apple ID settings. Prices may vary by region. PRIVATE BY DESIGN No account, no ads, no tracking. Rules sync through your private iCloud; Apple Health data and progress photos never leave your iPhone. HabitMint is now Main Arc β€” your habits, history and Pro came with you. Privacy Policy: https://ios.service-lab.site/mainarc/privacy Terms of Use: https://ios.service-lab.site/mainarc/terms
