Winter Arc: Lock In Challenge
90 Day Glow Up Streaks & XP
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
This winter, become the best version of yourself, one kept promise at a time.
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.

Did the work but forgot to tick it? You can now mark yesterday as done any time before midnight the next day, and your shield or your streak comes back.
Also new: add or swap a progress photo on any past day, and a help button on the home screen that opens the full guide.
