90-Day Challenge & Workout Log
Your 90-day Winter Arc challenge: choose your commitments, then track habits, workouts and steps with Winter Arc Pro. Start any day, your 90 days begin when you do.
Winter Arc 2026 is a 90-day challenge tracker for people who want to use the end of the year to build discipline. It brings your daily habits, gym log and step count into one plan, with reminders and a calendar of the days you showed up.
Your habits, workouts and steps, together in a 90-day challenge.
A clear direction. A week that fits you. A record of what you actually do.
Tracking your 90 days requires a Winter Arc Pro subscription.
• A plan that fits you: 3 to 12 commitments (gym, cardio, water, sleep, reading, journaling, phone-free moments…) and three difficulty levels: Strict, Progressive or Gentle.
• Your 90-day map, with your real dates, from the first day to the last.
• A strength log: exercises, sets, reps and loads in kg or lb, routines and workout comparisons.
• Your private photo of the day, and your arc’s film created on your device.
• Progress insights, reminders, widgets and optional read-only access to steps and sleep from Apple Health.
IN MY ARC, WITH PRO
See today’s steps and recent history from Apple Health. The goal starts at 10,000 steps; adjust it yourself or choose a suggestion based on your recent readable days. Review and save your choice: it will not change on its own. The connection is optional and read-only. Missing data does not mean zero, and no commitment is completed automatically. Measurements stay on your device.
WINTER ARC PRO
Tracking your 90 days is part of Winter Arc Pro: checking off your commitments every day, your workout log, your photo of the day and your arc’s film, progress insights, routines and comparisons, guided programs, up to 12 commitments, Health access, your daily reminder and your widgets.
Pro is available weekly or yearly, with exactly the same features. Each plan may start with a free trial for eligible Apple Accounts: its length, the amount and the first charge date are shown before you confirm. Subscriptions renew automatically unless cancelled in your Apple Account settings at least 24 hours before the end of the trial or current period.
Your journal stays on your device. Photos are optional; your movie is made locally from your real photos. Health access is optional and read-only. Your measurements never automatically complete commitments. Purchase verification uses Apple and RevenueCat.

What is a Winter Arc?
A personal challenge, popular on TikTok, where you commit to a few habits for about 90 days before the new year. There are no official rules.
Is it too late to start?
No. Your 90 days start on the date you choose.
How strict is it?
You pick your commitments and the level of strictness. A missed day stays in your history without erasing the rest.
Do I need to pay?
You can prepare your plan during setup. Daily tracking requires Winter Arc Pro, with the price in your currency shown before you pay.
