Every day you show up, you place a stone. Miss a day and the stone waits beside the stack — nothing topples. Pebbles is a tiny habit tracker for up to three daily practices. Tap once and the day is held. Miss a day and it stays open until tomorrow — tap it back in and your streak never knows. Away for a week? Mark it, and the chain holds. No streak freezes to earn. Nothing to buy back. BUILT FOR BAD WEEKS • A missed day waits for you — one tap makes it up, until it quietly locks • Away for a trip, an illness or a hard week? Mark those days away — the chain keeps, nothing is added • The two-minute rule, built in: one paragraph, one push-up — a day held • A calm bell at 2:00 tells you the day is banked, even from your pocket • Mark a day as missed on purpose — Pebbles respects the difference SMALL ON PURPOSE • Up to three practices, ever — the cap that keeps hard days possible • One tap to hold the day, one tap to undo; no forms, no numbers to log • No confetti, no XP, no guilt. The reward is the act of showing up. EVERYWHERE YOUR DAY IS • Check in from your Home Screen widget without opening the app • Time a session from the Lock Screen and Dynamic Island • A quiet daily reminder, and a nudge only when a streak is at stake • Full dark mode A QUIET RECORD • Your streak, longest run, total practice, average sit, and the time of day you usually show up • Practices can rest — every held day stays yours, bring them back anytime • Backed up to iCloud automatically. No account. No ads. No tracking. The science, honestly: habits don't form in 21 days. In UCL's habit-formation study they took about 66 on average — gains early, and a missed day didn't set people back. Pebbles is built for exactly that. Start with one practice.

Verdict
The clearest difference is update cadence: Pebbles at every 2 weeks against Health Aide's every 2 months. Health Aide's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
