Train hard. Track everything.
Own your data.
A beautifully simple HIIT interval timer and strength tracker, built for the gym floor: huge countdowns, one-tap set logging, and a weekly summary — all stored privately on your own phone.
HIIT interval timer
Work/rest/rounds with a giant ring countdown, get-ready phase, audio ticks in the final 5 seconds, and a screen that stays awake for the whole session.
One-tap strength logging
Tap a set and your last numbers fill in automatically. Nudge weight and reps with arrows. Custom exercise library for weights and calisthenics.
Weekly summary
Rolling 7-day view of cardio sessions, rounds, sets, best lifts, and total volume — the numbers that show you're progressing.
Private by design
Your workouts live on your device — not on our servers, not in a cloud profile. We couldn't sell your data if we wanted to. We don't want to.

Questions
Where is my workout data stored?
On your device only. HealthGuRu keeps your logs in your phone's local storage — nothing is uploaded to us. The trade-off: your history doesn't sync between devices, and clearing your browser data clears your logs.
Does it work on iPhone and Android?
Yes. Open the app in your phone's browser and choose “Add to Home Screen” (iPhone) or “Install” (Android). It runs full-screen like a native app and works offline.
How do I cancel?
Anytime, in two clicks, from the billing portal link in your receipt email. You keep access until the end of the period you paid for.
Is this medical advice?
No. HealthGuRu is a timing and logging tool. Consult your physician before starting any exercise program — see our Terms.
