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/

YOUR RULES Before day one you write your own rules. Three to seven of them, small enough to do on your worst day. Your rules can change whenever your life does: add one, drop one or reword one on any day, and the days you have already held stay exactly as you held them. WHO YOU ARE BECOMING Four stats, BODY, MIND, GRIND and IRON, drawn from the rules you actually wrote. Watch the shape change across ninety days. The most honest picture of a season you will get, you never chose the numbers, you chose the habits. EVERY DAY YOU SHOWED UP Tap the day number for your calendar: every day you held, every shield that covered you, every day still to come. DAY 90 Add a progress photo whenever you want. They stay on your phone, nowhere else. On the final day they play back as a summit montage, first day to last, beside everything you held and banked. THE MOUNTAIN Your home screen is a climb, not a list. Every day you hold your rules the climber moves up the face, past the treeline, onto the ridge, into the summit push. START ANY DAY Missed October 1? Nothing is lost. Pick your start date when you set up, today or any day ahead, and the app builds the same climb, the same camps and the same summit from there. A winter arc that starts on November 3 is still a winter arc. THE DAILY CHECK-IN The work is yours: the training, the pages, the early nights. Logging it is the quick part. Open the app, tick what you did, close it. Change your mind any time the same day; nothing is final until the day is. STREAK SHIELDS Miss a day and a shield goes instead of your arc. Your gear covers it and the climb continues. No red screen, no broken chain, no starting again from zero. WEEKLY BOSSES Each camp opens a challenge built from your own rules: one of them before 6am, seven days in a row, or done somewhere that is not home. Complete it and you bank a streak shield. Skip it and nothing changes. A challenge is an offer, never an obligation. AURA AND RANKS Every rule you close banks aura, and aura carries you through five ranks: Basecamp, Treeline, Ridgeline, Summit push, Summited. EVERY WEEK CLOSES Seven days make a camp, and each one ends with a recap of what you actually did rather than what you meant to do. Hold every day and the camp is perfect, which banks you a shield. WRITE THE DAY DOWN A line a day, if you want one. A sentence from a book, a note about why it was hard, a photo from the gym. They collect into a private timeline you can scroll back through from day one. A REMINDER THAT KNOWS WHEN TO STOP One nudge at the hour you pick, an optional evening save if the day is still open, and nothing at all once your arc is done. It ends when the season ends. BUILT TO BE LOOKED AT Two themes: Summit, dark and cold and quiet, or Glow, warm and light. Home screen and lock screen widgets so today sits one glance away and one tap from done. PRIVATE No account, no sign up, no feed, no leaderboard. Your arc lives on your phone and in your own iCloud, so it survives a new phone and a reinstall. None of it comes to us. Every screen opens before you decide anything, and Pro starts with a free week for eligible new subscribers, then renews automatically unless cancelled.
