Cold Shower Timer turns every cold shower, ice bath or plunge into one clear number: how long it takes your heart rate to settle. The cold hits as a spike. Your Apple Watch shows it live, and the moment your heart rate calms and holds steady, the watch marks it: Settled. Week by week, that moment tends to come sooner. ON YOUR WRIST • Big presets for wet fingers: 1, 2 or 3 minutes, or Next, which adds 15 seconds to your last session • Live heart rate during the cold, with your peak • The Settled moment, marked with its own haptic • Optional breathing haptics (in 4, out 6) and a tick every 30 seconds • Works without your phone, and saves each session to Health as a workout ON YOUR IPHONE • Today: the heart rate curve of your last session with the Settled marker • Your week at a glance: sessions, cold minutes, streak • A phone timer for days without the watch, including contrast shower rounds COLD SHOWER PRO, ONE-TIME PURCHASE • Adaptation: your time to Settled week by week, plus patterns such as mornings versus evenings • Full history with water temperature • Custom protocols and contrast shower intervals • Watch complication and Smart Stack card Your sessions stay on your devices. Usage analytics are off unless you turn them on. Cold Shower Timer is a timer and a log, not medical advice. If you have a heart condition, ask your doctor before cold exposure.

10,000 steps a day. No way out. OnBin turns your step goal into a game you can't ignore: on evenings you miss your goal, the apps you choose (yes, social media) get locked. Walk or no scrolling — your call. YOUR STEP BANK: A ROLLING BALANCE Unlike other step counters, every extra step you take is credit and every missed step is debt that carries over to tomorrow. One bad day won't ruin your month — the monthly average wins. Walked 15,000 on Sunday? 5,000 is enough on Monday. APP LOCKING (SCREEN TIME) If the goal isn't met, your selected apps lock from your chosen evening hour until midnight. The lock lifts the moment you hit the goal. Built on Apple's Screen Time framework — even we can't see which apps you pick. YOUR BALANCE SAVES YOUR STREAK Bad day? A positive balance quietly rescues your streak. No guilt, just momentum. LIVE ACTIVITY Remaining steps and a lock-hour countdown right on your Lock Screen and Dynamic Island. PRIVACY FIRST Your steps are read from Apple Health and never leave your device. No account, no ads, no tracking. • Rolling balance engine: monthly average, not daily all-or-nothing • App locking via Screen Time • Lock Screen and Home Screen widgets • Streaks, badges and monthly victories • Siri shortcuts: "How many steps left?" OnBin Pro: unlimited app locking, Live Activity and all badges. Try 7 days free.
