Tired of fitness apps interrupting your workout with ads or asking for subscriptions? I built this 100% free, browser-based interval timer for HIIT, Tabata, Boxing, and EMOM. Features: Zero ads, works completely offline, customizable rounds, keeps your screen awake automatically, and requires no app installation.

Hi Product Hunt! 👋 I’m the maker of this simple Interval Timer. The Problem: Every time I worked out, I got frustrated by mobile timer apps. They either had unskippable video ads right before a set, locked basic features behind a paywall, or forced my phone screen to sleep mid-workout. The Solution: I built a lightweight web app that solves all of that. ✨ Zero ads and totally free. 🔋 Uses the Screen Wake Lock API so your screen never dims. 📶 Works completely offline (just load it once). No bloated frameworks, just a fast, reliable timer you can use in any browser. I'd love to hear your feedback! Let's crush those workouts. 💪
