Sparkline: Habit Tracker

About

Sparkline helps you build habits that stick — one tap at a time. Tap the circle when you're done for the day. Watch your days light up. Keep going. WHAT MAKES SPARKLINE DIFFERENT • A visible finish line. The research most often cited puts habit formation at around 66 days, so every habit shows how far along it is — and graduates when it gets there. A habit is a project with an end, not a forever obligation. • Your history, at a glance. Every habit carries a heatmap of its recent weeks with its sparkline riding along the top. Runs glow brighter the longer they last, so you see the shape of your effort instead of just a number. • Schedules that fit real life. Every day, specific weekdays, or a weekly target. Rest days never break a streak, and reminders stay quiet on them. • Tie a habit to a routine. "After I pour my morning coffee" becomes that habit's reminder — if-then plans are one of the best-evidenced techniques in the habit research. • Missed a day? Sparkline says "pick it back up" and keeps your run in view. Never a guilt trip. • Milestones you can see: a ladder of streak marks, a ring filling toward your next days-done total, the 66-day seal and your perfect months — each one a card worth sharing. • Habits that repeat through the day — five glasses of water, medication three times — fill a ring as you go. • Archive instead of delete. The history stays, the slot opens up. • Fix any day. Tap it in the heatmap to log something you forgot. HABITS THAT CHECK THEMSELVES OFF • Apple Health, fourteen ways. Steps, workouts, exercise minutes, stand hours, activity rings, walking or running distance, cycling, flights climbed, active energy, water, sleep, mindful minutes, time in daylight, or simply stepping on the scale. Pick one, set the threshold once, and the habit checks itself off the moment you reach it — even with the app closed. A notification tells you it happened, so it never feels like a ghost. (Sparkline Pro) • Shortcuts automations, free for everyone. Arriving at the gym, tapping an NFC sticker on the vitamin jar, closing your reading app, plugging in the charger — any Shortcuts automation can log a habit. Sparkline adds two actions: Log Habit, and Is Habit Done for automations that should check before they act, like a 9pm nudge that stays quiet when you have already done it. EVERYWHERE YOU ARE • Home Screen and Lock Screen widgets — check habits off without opening the app, or keep one habit's heatmap in view • Apple Watch app — log from your wrist, synced both ways • Siri and Shortcuts — "Log my run in Sparkline", or an automation that does it for you • Reminders per habit, silently skipped once that habit is done ALWAYS FREE • Up to 5 habits, tracked forever • Completing habits, streaks, reminders, widgets and the Watch app • The last 30 days of your history SPARKLINE PRO — ONE PURCHASE, NO SUBSCRIPTION • Apple Health auto check-in: steps, workouts, activity rings, sleep, water and ten more data types check themselves off, hands-free • Unlimited habits • Full completion history from day one, not just the last 30 days • Trends: your best day of the week and an eight-week consistency trend • All-time statistics: longest streak ever, 30-day completion rate, total completions PRIVATE BY DESIGN No account, no sign-in, no servers, no ads, no tracking. Your habits live on your device. The privacy policy is three sentences long. 380+ icons in one clean style, eight colours to start from and a full colour picker when none of them is quite right — so every habit looks like itself.
