Your Winter Arc, tracked. The Winter Arc is simple: while everyone else coasts through the cold months, you lock in. Pick your window (Oct 1 to Dec 31 is the classic), write the daily rules you refuse to skip, sign your name, and show up every single day. WRITE YOUR NON-NEGOTIABLES Up to 10 daily rules: train every day, 10k steps, no alcohol, read 10 pages, up before 6, no phone after 9pm. Yours, in your words. Tap a suggestion or type your own. SIGN THE CONTRACT A contract card with your rules, your dates and your signature. Post it before day one. Telling people is half the discipline. CHECK IN. LOCK THE DAY. Every day, check off each rule. All of them done = a perfect day and a streak. Miss one and the grid shows it. No hiding. WATCH THE ARC FILL UP A 92-day grid (or however long you set), perfect-day streak, best streak, rules hit rate, days left. Share the progress card whenever you want. BUILT FOR THE LONG HAUL - Optional daily reminder at the hour you choose - Works fully offline. No account, no sign-up, nothing leaves your phone - Any dates: Oct 1 to Dec 31, 90 days from today, Nov 1 to Jan 31, or your own - Available in English, German, Spanish, Portuguese, French and Italian Free to use, supported by a small ad on the progress screen. Your check-in list stays ad-free, always. Winterlock is a habit tracker, not a coach or a medical tool. The only thing it measures is whether you kept your word.

About

Three Things Gratitude

Read full description

Gratitude Journal is the simplest way to practice a moment of gratitude every day. THREE THINGS, EVERY DAY No different question each day, no long forms. Every day you write the same 3 short things you're grateful for — whatever they are, as brief as you like. NO STREAKS, NO PRESSURE There's deliberately no streak counter and nothing that makes you feel bad for skipping a day. This isn't a challenge — it's a moment for you. YOUR HISTORY, ON A CALENDAR Revisit any past day from a monthly calendar — a dot under every day you wrote something. Tap a day to read back what you noted. A SHAREABLE MONTHLY RECAP At the end of the month, a nice card gathers how many days you wrote and a few of your standout moments — ready to share, or just to keep. It unlocks by watching a short, optional ad, never required to write or read your entries. DAILY REMINDER A gentle nudge at whatever time you choose, so writing becomes a small habit without you having to remember on your own. YOUR DATA STAYS ON YOUR DEVICE Everything you write is stored locally on your iPhone. No account required. AVAILABLE IN ENGLISH AND SPANISH The app automatically detects your device's language, and you can change it manually anytime from Settings. No gamification, no quizzes, no noise. Just three things, every day.
