Say “Start today’s workout” to Siri on your iPhone or Apple Watch, log sets by voice, and see your heart rate on every set — from your Watch or AirPods Pro 3. Strength, HIIT and core training for every level.
Try it free for 7 days.
One app for your training, your heart rate and the rest of your routine. Tap any feature to see it in action.
Per-set heart rate from your Apple Watch or AirPods Pro 3, mapped to every exercise — the core of how Iron Karnet trains with you.
Begin a workout on Apple Watch and your iPhone turns into a live dashboard — current heart rate, reps, sets, and step-by-step exercise instructions, all streaming in real time as you train.
Iron Karnet reads heart rate from whatever you're wearing. Start on your Apple Watch for wrist heart rate, or train with just your iPhone and AirPods Pro 3. No device at all? Every workout still tracks sets, reps, volume and progress.
After every session, Iron Karnet maps your heart rate to each exercise you performed — so you can see exactly which movements spiked your effort and how your intensity flowed across the whole workout.
Ready-made workouts and programs, circuits you design and plans you schedule — then see how far you’ve come.
Pick a ready-made workout for today, or follow a multi-week program built for home or the gym. Filter by time, category or equipment. Prefer your own routine? Build it, or scan a friend’s QR code to import theirs.
Create and arrange circuit-based HIIT workouts — group exercises into circuits, set work and rest, and fine-tune the flow before you train.
Schedule a workout in the app and it syncs straight to your Apple Watch — so when it's time to train, it's already there. No setup at the rack, just start and go.
A calendar of every session, a muscle map of what you’ve trained this month or year, and strength trends for every exercise — so every workout adds to the story.
Siri, Home Screen widgets, your Apple Watch and the Lock Screen — your workout is always one glance or one sentence away.
Train the same routine on the same day each week? Iron Karnet learns your weekly rhythm and has that workout ready again next week — on your Home Screen widget, on your Apple Watch, and when you ask Siri. No scheduling needed.
Start a session and it lives on your Lock Screen and in the Dynamic Island — live heart rate, your current exercise and a rest timer counting down. Between workouts, Home Screen widgets show today’s workout and let you log water in one tap.
The full picture of your training and health, syncing automatically with Apple Health.
Catalog supplements, scan labels with OCR, plan daily intake schedules, set reminders, and see full macro & micronutrient breakdowns.
Log daily hydration, set personal goals, schedule reminder notifications, and watch your weekly and monthly trends climb.
Push and pull workouts, weight, water, supplements and body measurements to and from Apple Health automatically — no manual double-entry.
Log weight, body-fat % and per-muscle-group circumferences, with left/right symmetry analysis and one-tap HealthKit import.
