Hey Product Hunt! 👋 I built ОДИН·ДВА (One-Two) because every interval timer I tried was either full of ads, required registration, or stopped working when my phone screen locked. One·Two is a free PWA interval timer for HIIT, tabata, strength and cardio workouts: • Custom work/rest intervals with round counter • Different music tracks for work and rest phases • Full offline support after first visit • No ads, no registration, all data stays on your device Built with vanilla JS/HTML/CSS — no frameworks, no backend. Works on any device directly in the browser, and can be installed as an app without an app store. Would love your feedback! 🙏
