Surge: HIIT & Interval Timer

Surge is a clean, fast interval timer built for real workouts — HIIT, Tabata, EMOM, or anything you design yourself. Pick a preset and go, or build your own from scratch: set your work time, rest time, and rounds, name your exercises, and Surge counts you through every second on a full-screen display made to be glanced at mid-rep. FEATURES - Built-in presets — Tabata (20s/10s × 8 rounds), HIIT 30/15, EMOM 10, and the classic 7-Minute Workout - Custom workout builder — any exercises, any work/rest times, any number of rounds - Voice cues — hear "Get ready," "Work," "Rest," and your exercise names called out loud, so you never have to look at your phone mid-set - Sound and vibration alerts on every phase change and countdown - Workout history — track your day streak, sessions this week, and total workouts completed - Light and dark themes - 11 languages — English, Spanish, Mandarin Chinese, Hebrew, Arabic, Russian, French, Bengali, Portuguese, Indonesian, and German, with full right-to-left layout support - Keep-screen-on option, so your workout is never interrupted by your phone locking - Works fully offline — once installed, no internet connection needed Surge is a one-time purchase of $10 — no subscription, ever. No ads, no account required, and no data collection of any kind: your settings and workout history stay on your device, never on a server. Whether you're doing a quick 7-minute session at home, running Tabata rounds at the gym, coaching a class through custom intervals, or timing any kind of work/rest routine, Surge keeps time so you can focus on the work.
