Streaky: Habit Tracker のアプリ分析 10月21日

Build habits that actually stick — one day at a time. Streaky is a privacy-first habit tracker that turns daily intentions into lasting routines. No sign-up, no cloud, no tracking. Everything lives on your phone. WHY STREAKY • Streaks that motivate. Watch your chain grow day after day, with confetti at 7, 30, 100 and 365 days. • You vs you. This month against last month, this week against last week, and your best week on record — the only comparison that predicts whether a habit sticks. • Shareable streak cards. Turn a streak into an image for your story or a group chat. Nothing is uploaded; the card is drawn on your phone and handed straight to the share sheet. • Rich statistics. Progress rings for today, week and month. Donut breakdowns by habit. Weekday rhythm charts, all rendered natively. • GitHub-style heatmap. Fifteen weeks of progress at a glance. Tap any day to log a check-in, however long ago it was. • Your schedule, your rules. Start a habit on a future date. Skip a day for a holiday or an illness without breaking the chain. Add a one-off task for a single date — it archives itself once the day has passed. • 24 achievements. Early Bird, Night Owl, Weekend Warrior, Perfectionist, Iron Discipline. They unlock on patterns, not just on length. • Smart reminders. Pick the exact time and the exact weekdays for each habit. Local notifications only; nothing reaches a server. • App Lock. Optional Face ID, Touch ID or device passcode. Your habits stay yours even if someone picks up your phone. • XP and levels. Every check-in earns XP. Streaks pay bonuses. Rise through nine ranks, from Seeker to Habit Deity. • 50 languages. Switch anytime in Profile, independently of your device language. PRIVACY FIRST Streaky has no backend, no account system, no cloud sync and no analytics. Every habit, check-in, streak and achievement lives only on your phone. Google AdMob serves non-personalized ads by default so the app can stay free — no behavioral profile of you is ever built. Export your data as JSON whenever you like. Reset everything with one tap. Uninstalling wipes it all. WHO IT IS FOR — People who want to build daily habits without a subscription. — Minimalists who would rather not hand a wellness app their data. — Anyone who prefers offline-first tools that respect privacy. — Anyone who wants a habit app that opens fast and gets out of the way. Free forever, with optional rewarded ads to unlock extra habit slots. No dark patterns, no nagging.
