Strikai vs Winter Arc

Pick a challenge. Show up every day. Miss one and you are back to day one. Strikai is a strict challenge tracker for discipline, streaks and fixed-duration self-improvement. Keep the chain alive across fitness, focus, cold exposure and clean reset routines. Choose real challenges like 75 Soft, Winter Arc, Cold Shower 30, Monk Mode, No Alcohol 30, No Sugar 30, Screen Detox and more. Complete daily tasks, protect your streak, hit milestones and finish what you started. Strict mode keeps it honest: miss a required day and the challenge resets. Use limited day rescue when life gets in the way, or accept the reset and start again. No account. Works offline. Your data stays on your device. Upgrade to Strikai Pro for no ads, premium themes, detailed statistics and unlimited day rescues. One day or day one.

Winter Arc: Habit Tracker turns the last stretch of the year into one finite challenge. Pick a hard start and a hard end. Choose three to five pillars — the areas you actually want to move — and put a few daily non-negotiables under each. Then show up. Every day is binary: done, or not. Ninety days later you come out the other side, carrying momentum into January instead of writing resolutions from a cold stop. HOW IT WORKS • Set your dates. Ninety days by default, or any span you choose. • Choose 3–5 pillars, with one to three habits under each. • Check them off daily. No half marks, no partial credit. • Watch the arc fill in. CHOOSE YOUR RULES People don't all fail the same way, so you decide what a missed day costs. • Streaks — consecutive days where you completed everything. Simple and strict. • Consistency Score — the percentage of habit-days you completed against a target you set. Forgiving of the occasional miss. • Grace Days — a fixed budget of missed days. Spend them all and the arc is failed. You set the budget. SEE THE WHOLE ARC • A heat map of every day, so the whole arc is one picture. • Your consistency score, longest streaks, and a breakdown by pillar. • Tap any past day to see exactly what happened. • Weekly reflections, and a closing reflection when the arc ends. WHEN YOU MISS A DAY Missing a day isn't a crisis and the app doesn't treat it like one. You get one quiet note, the reason you started, and a clean slate. Run out of grace days and you choose what happens next: keep going with the arc marked failed, or restart with the same setup. BEFORE AND AFTER Add a photo at the start and another at the end, and see them side by side. Both stay on your device. Entirely optional. ON YOUR HOME SCREEN A widget shows the day you're on and how many habits are left, and updates as you check them off. PRIVATE BY DEFAULT No account. No sign-in. No analytics, no advertising, and no third-party code of any kind. The app has no networking at all, so nothing can leave your phone even by accident. Everything lives in the app's own storage, and Reset app data erases all of it. Winter passes either way. Finish the year strong.
