Coaches say rest 3–5 minutes between sets. TikTok takes 54 a day. GYMROTTER is the rest timer that shields your phone between sets. When the rest clock starts, distracting apps go dark. When it hits zero, the bell rings and the iron calls you back. THE SHIELD Pick the apps that steal your rest. GYMROTTER blocks them with Apple's Screen Time — no willpower required, no half measures. THE CLOCK A rest timer built for lifting: set-by-set logging, a Live Activity on your Lock Screen and Dynamic Island, and a nudge the second rest ends. THE FORGE Every shielded minute counts. Earn XP, climb the tiers from Wood to Obsidian, keep the streak, and stamp your sessions with a shareable Training Certificate. THE LEDGER See exactly how much time the scroll used to take — and how much you took back. Built for people who go to the gym to lift, not to watch other people lift. — Gym rest timer. Workout interval timer. App blocker for lifting. Screen time discipline for the gym. Rest between sets, focused strength training. privacy: https://dapsdev.dev/gymrotter/privacy tos: https://dapsdev.dev/gymrotter/terms
