How we celebrate you
Losing weight — or holding a healthy one — is slow, quiet work. So the tracker borrows a trick from our arcade: a four-tier reward ladder that notices the moments worth noticing and gives each the right-sized celebration, from a little sparkle to full fireworks.
The four tiers
What the app watches for
The tracker quietly records your readings and, whenever you log, checks for events it hasn't celebrated yet — then fires the highest one. Each is recognised only once, so nothing spams you (importing years of history won't set off a hundred fireworks; those are marked as already-earned, silently).
- Every weigh-in → Spark, and your streak grows.
- A new best trend in your goal's direction → Nice.
- Weight-change bands — each 10 lb (or 5 kg) closer to goal → Amazing.
- Streaks — 7 days (Amazing), 30 and 100 days (Legendary/Amazing).
- Halfway to goal → Amazing.
- Anniversaries — a month, 100 days, a year of tracking.
- Goal reached and −10% of bodyweight → Legendary.
Want to see them now?
Open the Weight Tracker and either tap any badge under "Your journey" to replay its celebration, log a reading that crosses a milestone, or hit Load demo data — it replays the biggest reward you've earned. (Celebrations respect your system's "reduce motion" setting.)
And it's all private: every reading, streak and milestone lives only in your browser.
