Nibble

Nibble turns any number you care about into a Home Screen widget — and into a tiny pixel pet whose mood follows your progress. Free forever: one number of your own, plus Steps or Water from Apple Health. Steps, revenue, water, savings, words written: if it's a number, Nibble can show it. HOW IT WORKS 1. Start with a preset — Steps, Water, Bitcoin, Ethereum — or bring your own number with the "Set Nibble Value" Shortcuts action or any JSON URL. 2. Pick a layout: Big Number, Progress Ring, Sparkline, or Pixel Pet. 3. Add the widget, set a goal, and watch the ring fill — and the pet react. THE PET Your pet's mood is driven by your own metric — never by social points, a leaderboard, or anyone else's numbers. Beat your goal and it celebrates. Fall behind and it gets hungry. Five moods, animated pixel art, and zero guilt-trip notifications: the only reminder Nibble can send is one daily check-in you switch on yourself, and it never names your metric or shows its value. STREAKS THAT DECORATE, NOT NAG Meet your goal on consecutive days and your pet earns its look: sunglasses at 3 days, a crown at 7, a full aura at 30. Miss a day and the run just resets — no notification, no red badge, nothing to buy back. A day you earned stays earned, even if the number moves again later. FOUR WAYS TO FEED IT — ALL CODELESS • Presets: Steps and Water from Apple Health, Bitcoin and Ethereum spot prices — tap once, no setup • Apple Health: read-only, Steps and Water only, and the numbers never leave your device • Shortcuts: anything Shortcuts can measure, Nibble can display • Any JSON endpoint: paste a URL, pick a key path, test the fetch before saving ON YOUR HOME SCREEN AND LOCK SCREEN • 4 layouts: Big Number, Progress Ring, Sparkline, Pixel Pet • Lock Screen widgets too — circular and rectangular • Tap "+1" right on the widget to bump a manual count without opening the app — and give each metric its own step, so Water moves by 1 while Calories moves by 100 • Beat a goal and you can share the moment, if you feel like it: a clean card, or a retro handheld card sized for Stories with your streak on its screen • 8 accent colors and a rounded, friendly type scale NO ACCOUNT, NO TRACKING • Everything stays on your device. No account, no analytics — the privacy label says "Data Not Collected" because there is nothing to collect • Widgets refresh on iOS's schedule and keep the last value when offline — honest by design FREE AND PRO Free, forever: two metrics — one number of your own, plus Steps or Water from Apple Health — shown as a Big Number, with the Pixel Pet on your main one. Lock Screen widgets, "+1" tapping with your own step size, streaks and the whole pet evolution, and both share cards are free too. Nibble Pro ($4.99, one-time purchase): unlimited metrics — a whole zoo of pets — with all four layouts on every one of them, and the skin collection: Pixel Cat, Cyber Dragon, Retro Robot. No subscription. Your number, your way.
