You don't need another empty checklist. You need the plan, and someone who notices when you go quiet. Bloom is a 75 day challenge tracker that hands you the whole thing on day one โ€” the daily rituals, the streak, the calendar, and a companion who actually checks. PICK YOUR CHALLENGE Glow Up 75, Winter Arc, That Girl Era, Main Character 30, Soft Life Reset, Strong in 21 and more. Each one arrives with its own daily rituals, so you're never staring at a blank list wondering what to track. Prefer your own? Build it, from 21 to 75 days. TICK OFF YOUR DAILY ROUTINE Water, workout, reading, skincare, sleep, journalling โ€” whatever your challenge asks for. Your progress is a plant that grows on the days you show up. KEEP THE STREAK ALIVE One shield a week absorbs a missed day. A single bad day doesn't end the journey, because that's the day most people quit. DO IT WITH A FRIEND Share your 6-character code and you're paired. Two streaks side by side โ€” she sees your day, you see hers. Accountability that isn't a group chat you mute. A COMPANION THAT CHECKS IN Pick her personality. She asks whether the routine got done, notices when you disappear, and talks you out of quitting instead of watching you go. YOUR PROGRESS, ON CAMERA Save a photo against any day and watch 75 days of yourself line up in one grid. Photos stay on your phone โ€” we never upload them. HOME SCREEN WIDGETS Today's rituals and your day count, on your home screen, in your colors. THE WHOLE JOURNEY A calendar of every day you showed up, from day 1 to the last one. BLOOM+ Unlocks every challenge, the full calendar and unlimited check-ins. Or buy a single Challenge Pass for one journey, with no subscription at all. Bloom works for any routine you're trying to make stick: gym, skincare, study, sleep, water, journalling, screen time. 75 days. One challenge. Someone who checks.

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.
