Rest

Your phone's timer doesn't know the difference between a deadlift and a bicep curl. Rest does. Rest is the gym timer that thinks so you don't have to. It auto-adjusts your rest periods based on what you're actually lifting โ heavy compounds get more time, isolation moves get less. No fumbling, no thinking, no forgetting to start the timer. YOUR REST PERIODS, SORTED 5 tiers of smart rest. Heavy compound (4 min), compound (3 min), accessory (2 min), isolation (90s), light isolation (60s). Every exercise in the database comes pre-categorized. Override any exercise's rest time and it remembers forever. LOCK SCREEN & DYNAMIC ISLAND Your timer lives on the lock screen via Live Activities and in the Dynamic Island. See your countdown, exercise name, and set info without touching your phone. Adjust +/- 30s right from the lock screen. Hands stay chalked. LOG FAST, GET BACK TO LIFTING Weight and reps โ that's it. No RPE scales, no tempo fields, no 47-step wizard. Last session's numbers are pre-filled so you just tap the checkmark. Set logged. Timer started. Done. MARKDOWN EXPORT One tap copies your entire session as clean Markdown. Paste into Notion, Obsidian, Notes, wherever you keep your training log. No CSV gymnastics, no third-party integrations. ROUTINES Save your splits as templates. Push Day, Pull Day, Legs โ tap and go. Or start an empty workout and build as you lift. BUILT FOR PRIVACY No account. No cloud. No tracking. Your data lives on your device and nowhere else. We don't know your name, your PRs, or your gym crush. Apple's "No Data Collected" privacy badge โ because we actually mean it. ONE PRICE. FOREVER. Free tier: 5 exercises per session with full timer + Live Activities. Pro: unlimited everything for $19.99. One time. No subscription. No "annual plan that's actually monthly." Buy it like a pair of lifting straps โ once.
