The winter arc. For real this time. 90 days. 9 rules. Zero excuses. Winterarc isn't just another habit tracker. It's a challenge. You commit to 90 days, check off your rules every day, and watch your discipline build, square by square. HOW IT WORKS Pick your Day 1. The app tracks you for 90 days on the winter arc rules: water only, no fast food, 7–8 hours of sleep, the gym, running, 10,000 steps, no phone at the table, 20 minutes outside, gratitude. Every night, you check in. Every week, your flame grows. Every day fills a square. YOUR PROGRESS AT A GLANCE 90 squares. One a day. The longer you hold on, the more of them light up. It's the view that reminds you where you're at, and everything you've already built. THE FLAME ONLY FORGIVES ONCE Complete your full week and your flame rises. Miss a week and your freeze saves it. Just once in the whole arc. After that, it's on you. DAY 1 VS DAY 90 On day one, you take a photo. It stays locked on your phone. Nobody sees it, not even you. On day 90, you take a second one, and the app shows them side by side. That's when you really see what 90 days have changed. WE WON'T LET YOU SLACK OFF An evening reminder if your day's dragging. An alert if your flame's in danger. A line every morning to get your head back in the game. That's it, no spam. YOUR RULES, YOUR ARC (PRO) Want 5 workouts instead of 4? Add "read 50 pages"? Drop a rule? Pro lets you build your arc your way, with your own icons and colors. APPLE HEALTH SYNC Your steps check themselves off. The rest is up to you. Winterarc runs on iPhone. Your data is yours: your photos never leave your device. The winter arc is that stretch of winter where you put in the work quietly while everyone else waits for January. Six months of focus can make up for six years of garbage. So, are you in?

Lâche rien sur ton winter arc 🔥 ### 3/5 — Vraiment dommage *2026-10-05* Très dommage qu’on doivent payer pour modifier les règles, j’aurais par exemple préférer des pubs pour modifier les règles **Developer response:** Je comprends ! J'ai voulu une app sans pub. Par contre, avec la mise à jour qui arrive, tu pourras avoir Pro sans payer : chaque pote que tu invites et qui fait sa première journée pleine t'offre un mois (jusqu'à 12) ! ### 1/5 — Application vide *2026-10-01* Aucun but à par ajouter qu’on a bu de l’eau et pas manger de fast food pour une application qui nous permet de nous défier je ne vois pas l’intérêt passer votre chemin **Developer response:** Cocher « eau », c'est facile ; le faire tous les jours pendant 90 jours sans craquer, c'est une autre histoire, et c'est tout le principe 😉 Mais j'ai bien noté le côté défi : avec la mise à jour qui arrive, tu pourras défier tes potes en duo ou en groupe ! ### 4/5 — Bonne app MAIS !! *2026-10-01* Dommage qu’on est besoin de paye pour rajouter des défi mais dans l’ensemble sa va **Developer response:** Merci pour ton retour ! Les règles perso restent dans Pro, mais avec la mise à jour qui arrive, tu pourras te défier avec tes potes en duo ou en groupe, et ça c'est gratuit 🔥 Et chaque pote que tu invites t'offre un mois de Pro dès sa première journée pleine. ### 5/5 — . *2026-10-01* L’application est vraiment bien faite et complète **Developer response:** Merci Axel, ça me motive à fond ! Et c'est que le début, attends de voir la prochaine mise à jour 👀 ## Frequently asked questions about Winterarc ### What is the Winterarc challenge?

A new look • A Home that lights up: your cards' borders glow in the color of every rule you check, and your week turns into moons that fill up. • "My winter arc" redone as widgets: your journey, completion, perfect days and streaks at a glance. • Three new widgets: My Journey, My Progress and My Stat (Pro). With friends • Duo: do your winter arc with a friend and keep a flame going together. • Groups: 3 to 30 friends (up to 100 for creators, on request), each with their own rules, a leaderboard every week. • The streak leaderboard, and your link winter-arc.fr/@username: every friend who finishes their first full day gets you a month of Pro (up to 12). Your arc, your way • Three modes: Hard (all 9 rules from day 1), Progressive (one more rule every other day) or Soft (gentle routines). • No Nut November, November 1 to 30, next to your winter arc or on its own (sign-ups open October 25). • Warrior or goddess: pick the style of your artwork, plus two glow up programs, "Pilates princess" and "That girl". • No Mercy mode: your reminders stop being polite (Settings → Coaching). Every day • Check off your rules from the Lock Screen in the evening, or with a tap on the widget. • Your sleep checks itself off with Apple Health. • The daily photo: nobody sees it, not even you, until your timelapse on the last day. What's next • Your recap card by card, ready to share as a story, then a new arc of 30, 60 or 90 days. • The January 1st start with a New Year countdown, and an arc for every season: spring arc, summer arc. • Also: pick up where you left off after a few days away, and an incomplete first week no longer costs you your freeze. ### 1.0.3 — 2026-10-03 Salle et course : la règle change, en ta faveur. • La salle (4 fois par semaine) et la course (2 fois) ne bloquent plus ta journée. Journée pleine = tes règles quotidiennes. La salle et la course se jugent sur la semaine, d'ici dimanche. • Semaine incomplète (départ un jeudi, par exemple) : objectifs réduits d'autant. • Tes semaines passées sont recalculées avec la nouvelle règle : un gel ou une flamme perdus à cause de ça te sont rendus. • Raté le 1er octobre ? Le 1er novembre est le prochain départ collectif : choisis-le pour ton jour 1. Le 1er janvier suivra. • Jour 7 et jour 30 : ta story est prête. Ta grille et tes stats, sur une illustration, sur ta photo ou sans fond, à poster en un geste. • Notifications plus utiles : le bilan de ta semaine le lundi, la séance qui manque le dimanche, les règles qu'il te reste le soir. • Le widget se met à jour dès que tu ouvres l'app. • Corrections et petites améliorations. ### 1.0.2 — 2026-09-29 Le 1er octobre, c'est parti. • Compte à rebours plein écran jusqu'à ton jour 1. Le jour J, ton winter arc est pris dans la glace : trois taps pour la briser. • Au moment de choisir ta date, tu vois combien de personnes partent avec toi. • Nouveau dans Pro : 6 programmes prêts (mode hard, monk mode, muscu, course, études, tête froide) et les widgets pour l'écran d'accueil et l'écran verrouillé. • Connexion avec Google. • L'app parle maintenant anglais, espagnol, italien et allemand. • Corrections et petites améliorations. ### 1.0.1 — 2026-09-24 Le vrai winter arc démarre le 1er octobre. Tu peux maintenant le rejoindre en un tap, ou choisir ta propre date. - Départ le 1er octobre, comme tout le monde, ou à la date de ton choix - Compte à rebours sur l'accueil jusqu'à ton jour 1 - Un rappel chaque soir avant le départ pour arriver prêt - Réglage « Statistiques anonymes » pour nous aider à améliorer l'app ### 1.0 — 2026-09-16 No release notes. ## Apps similar to Winterarc | App | Rating | Price | Category | | --- | --- | --- | --- | | [Winter Arc - 90 Days Challenge](https://appshunter.io/ios/app/winter-arc-90-days-challenge/id6801043027) | — | Free | Health & Fitness | | [Winter-Arc](https://appshunter.io/ios/app/winter-arc/id6812017241) | — | Free | Health & Fitness | | [IRONIQ – AI Fitness Coach](https://appshunter.io/ios/app/ironiq-ai-fitness-coach/id6770323344) | 4.9 (8) | Free | Health & Fitness | | [Fibi - AI Gym Coach](https://appshunter.io/ios/app/fibi-ai-gym-coach/id6809485696) | 4.3 (4) | Free | Health & Fitness | | [Winter Arc by Coldstart](https://appshunter.io/ios/app/winter-arc-by-coldstart/id6736709926) | 5.0 (42) | Free | Health & Fitness | | [Winter Arc: Lock In Challenge](https://appshunter.io/ios/app/winter-arc-lock-in-challenge/id6807204714) | — | Free | Health & Fitness | ## More apps by Victor Gassmann - [Carnet de Musculation: MaxOut](https://appshunter.io/ios/app/carnet-de-musculation-maxout/id6758412788) - [MindStep - Marche méditative](https://appshunter.io/ios/app/mindstep-marche-meditative/id6766339941) All apps by Victor Gassmann: https://appshunter.io/developer/1843091685 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
