Heart of yours
Every beat counts
Free · Designed for iPad. Not verified for macOS.
New: a plate calculator and warm-ups worked out for you, a default rest for every kind of exercise, and sessions you can add to a program already running.
A workout log that gets out of your way.
Plan a session, tick off every set, watch your lifts grow. Heart is a minimalist gym tracker: 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.
Train to a plan
• 19 ready-made programs, each with the research behind it, or one made from your own templates
• Heart schedules the sessions, fills in every set's target and adds weight when you earn it, starting from your own history
• Add a session as you go, set a day aside with Not today, and name what to go easy on for kinder swaps
Log a session
• Weight and reps, time or distance, in kilograms or pounds, with last time's numbers on every set
• Rest timers per exercise, or one default for every kind of exercise
• A plate calculator for barbell and machine weights, and warm-up sets worked out for you
• Supersets, rep ranges, warm-up, drop and failure sets, and RPE if you want it
• Templates in folders, and a library you can search by muscle, movement or nickname
See it add up
• Personal records at every rep count, and lifetime totals
• Charts for every exercise across your whole history, plus volume, sets and workout length by week or month
• A muscle map of what you trained, and sets a week by movement pattern
• Goals you set yourself, with the rungs on the way to them
On your wrist
Log sets from your Apple Watch with rest, last time's numbers and heart rate. Leave the phone in the locker: the watch keeps logging and the iPhone catches up.
Health, on your terms
Heart shows your resting heart rate, heart-rate variability, sleep, steps, active energy and weight from Apple Health alongside your training, and saves each finished workout back to Health 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.
Your data is yours
• Import your history from Strong or Hevy
• Export everything as JSON or CSV, any time, with or without an account
• A read-only API and MCP, so your own scripts and AI assistant can read your log
Built for the device you own
iPhone and iPad, in both orientations. On iPad, History and Exercises open two panes, not a phone layout stretched wide. Siri, Shortcuts, widgets and the Lock Screen too.
Most features added after the basics ask before they show up, and every one turns off in Settings as if it had never been built.
Free. No ads. Nothing to subscribe to.
