Heart of yours: Workout Log

A workout tracker that gets out of your way.

Plan a session, tick off every set, watch your lifts grow. Heart is a minimalist gym and strength-training log, an exercise log with: no feed, no streak guilt, no upsell in the middle of a working set.

Start without an account

Open the app and train. Your workouts, templates, custom exercises and goals live on your phone from the first session. No sign-up, no email. Log in whenever you like and everything you logged first comes with you — nothing is left behind.

Log a session

• A rest timer between sets, on the workout screen where you need it
• Weight and reps per set, in kilograms or pounds
• Save any session as a template, and file your templates in folders
• Your own exercises, alongside a library you can search by muscle group

See it add up

• Personal records at every rep count, and lifetime totals
• Charts per exercise and per week, on a dashboard that is yours to arrange
• Goals you set yourself, with the rungs on the way to them

Health, on your terms

Heart shows your resting heart rate, heart-rate variability, sleep, steps, active energy and weight from Health Connect alongside your training, so you can see how they move together — and it saves each finished workout back to Health Connect so your rings credit your lifting.

Health data never leaves your device. Not the readings, not averages of them, not in a crash report, not in an export. There is no server table for it, because there is no server call for it.

Your data is yours

• Export everything as JSON or CSV, any time, with or without an account
• Erase everything on the phone, in one place in Settings
• Bring your history with you: import a CSV from another tracker

Built for the device you own

Phones and tablets, in both orientations. On a tablet, History and Exercises open two panes and the tab bar becomes a rail — not a phone layout stretched wide.
