Most challenge apps ask you to pay before you've finished week one. Arc doesn't. The 30 Day Reset isn't a trial version. It's the whole thing, all thirty days, free, and it stays free. Pick a challenge, tick your tasks, watch a row of empty boxes fill in one a day. That's the app. No feed, no friends list, no leaderboard, and nothing in here calls you champ. FIVE WAYS TO START 30 Day Reset. Three habits you choose yourself. Free. 66 Day Habit Builder. Three to five habits, and sixty-six days because that's the number the research keeps landing on. 75 Day Classic. Two workouts, a diet, water, reading, a daily photo. 75 Day Gentle. Same seventy-five days with one workout and a bit of air. Custom. Your rules, 21 to 90 days. APPLE HEALTH DOES THE BORING PART Switch on auto-tracking for a task and Arc reads your steps, exercise minutes, outdoor workouts, water and mindful minutes, then ticks it off without being asked. It only ever reads. Nothing gets written back to Health, and none of it leaves your phone. Don't want to grant that? Those tasks stay manual and the rest of the app doesn't care. SEASONS Shared start dates run through the year: Fall Lock-In, Winter Arc, New Year Arc, Spring Reset, Summer Arc. Begin on one and its stamp goes on your finisher card. Starting tomorrow instead is also a perfectly good plan. STRICT MODE, OFF BY DEFAULT Turn it on and a missed day sends you back to Day 1. You get one grace day for the whole run, and once it's gone it's gone. The card at the end looks the same either way. THE FINISHER CARD Reach the end and Arc prints you a card: day count, completion rate, longest streak, and the sentence you wrote on day one about why you started. Square, story, or wide. Save it to Photos or send it straight out. Widgets put the day count and what's left on your home screen and lock screen. The medium one lets you tick things off without opening the app. WHAT ARC WON'T DO No account, so there is no email and no password to lose. Your data sits on your phone and in your own iCloud, and I can't see any of it. No ads. Progress photos stay in Arc on your phone. Nobody checks them, nobody looks at them. FREE, PERMANENTLY The 30 Day Reset in full. One custom challenge. The small widget. Your finished history. Apple Health auto-tracking. ARC PRO Every template, unlimited custom challenges, several running at once, all the widget sizes including the interactive one, and the finisher card in all three shapes. Pay by the month or the year, or buy it once and it's yours. Arc syncs through your own iCloud, so a new phone picks up where the old one stopped. Turn iCloud off and everything still works on the device. Privacy: https://arc.wuyuxai.com/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
