The next 90 days can change everything. Arc is the 90-day challenge tracker built for your Winter Arc. Pick a start date, write your daily rules, sign your contract — then lock in and show up every single day. No account. No subscription. Your arc lives on your phone, not on someone's server. 【WRITE YOUR RULES, SIGN YOUR CONTRACT】 Choose your daily non-negotiables — wake up early, train, read, cold showers, no doomscrolling — from templates or write your own. Then seal them with your real signature. Changing a sealed contract takes a formal amendment, and you only get three. Your word should mean something. 【A STREAK THAT DOESN'T PUNISH YOU】 Most challenge apps delete your progress the moment you slip. Arc never resets you to zero. Missed yesterday? Rescue it within 48 hours. Life happens? Grace days give you weekly breathing room. Fell off completely? Restart from Day 1 with your history preserved. The goal is finishing 90 days — not being perfect at them. 【WATCH YOURSELF CHANGE】 A 90-square heatmap fills in day by day, next to your completion ring and streak. Milestones at Day 7, 30, 60 and 90 come with real celebrations. Add photos to your private journal and let the Journey report turn your arc into a story: where you started, where you are now. 【SHARE THE PROOF】 One tap renders a clean progress card — day count, completion rate, streak — made to be shared. Let your friends know you're locked in. 【KEEP IT IN SIGHT】 Home screen and lock screen widgets keep your day count staring back at you, and a daily reminder with a stoic quote makes sure you never quietly drift. 【WHEN THE 90 DAYS END】 Your next arc is waiting. New Year Arc, Spring Arc — the ritual repeats, your past arcs stay on the shelf, and the person who finished the last one starts the next. Arc is free for the full 90 days. A single one-time upgrade unlocks unlimited grace and rescues, advanced stats, and theme packs — no subscription, ever. Your future self is watching. Lock in. 【Terms of Use (EULA)】 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
