FAQ & Support

Open Iron Karnet on your iPhone, pick a category — Strength, HIIT or Core — and choose a built-in workout or create your own. Tap start, and your live dashboard tracks reps, sets and heart rate as you go. To train from your Apple Watch instead, schedule the workout for today or add it to your favourites first; it'll then be ready to run on your wrist.

Iron Karnet remembers the workout you did on each day of the week. When that day comes round again, the same workout is ready as today’s workout — no scheduling needed. Ask Siri “What’s my workout today in Iron Karnet?” or “Start today’s workout in Iron Karnet”, see it on your Home Screen widget, or start it straight from your Apple Watch. A workout you’ve scheduled for that day, or one from an active program, takes priority.

No. Starting a workout in the iPhone app runs it on your iPhone only — it does not launch or start the workout on your Apple Watch. To train from your wrist, start the workout on the Apple Watch itself, using one you've scheduled for today or added to your favourites. Each device runs its own session.

Yes. Once a workout is scheduled for today or saved to your favourites, your Apple Watch can start and run it entirely on its own — your iPhone doesn't need to be nearby. Train with wrist-based heart rate, finish the session, and it syncs back to the iPhone app later, once your devices reconnect. The iPhone app is there for reference — such as reviewing exercise instructions — but you don't need it with you to complete a prepped workout on your wrist.

You have options. With AirPods Pro 3, just wear them and make sure Heart Rate is turned on in iOS Settings → tap your AirPods → Heart Rate. If you start the workout on your Apple Watch, it streams wrist heart rate automatically. And with no device at all, your workout still tracks everything except heart rate.

Good to know: when you start a workout in the iPhone app, the Apple Watch does not use its heart rate sensor — use AirPods Pro 3 for heart rate on iPhone-started workouts.

In the app, create a strength session by adding exercises and setting your reps, sets and target weights, then save it as a reusable routine. To share it, show its QR code to a friend — they can scan it to import your workout instantly.

Iron Karnet runs on iPhone as your main training hub, with a native Apple Watch companion app. You can also track heart rate with AirPods Pro 3, and everything stays in sync through Apple Health.

No. Apple Watch gives you the full wrist-native experience, but it's optional. You can run a complete workout from your iPhone alone and still get live heart rate from AirPods Pro 3. Even with no heart rate device, every workout still tracks your sets, reps, volume and progress.

AirPods Pro 3 have an in-ear heart rate sensor that Iron Karnet reads during iPhone workouts — just turn on Heart Rate for your AirPods in iOS Settings. Your heart rate then appears live on your workout dashboard, exactly as it would from an Apple Watch.

Most exercises come with an animated demo and step-by-step instructions — a few have instructions only for now. On Apple Watch, the demo plays right on your wrist while you train, so you can check your form without picking up your phone. On iPhone, open the Instructions tab during a workout or tap any exercise to see its demo. For sharper, HD demos on iPhone, download the free HD demo pack from within the app; until it’s downloaded, you’ll see the standard demos.

The Apple Watch app is a companion for running workouts you've already set up on your iPhone. Schedule a workout for today or mark one as a favourite, and it's ready to run on your wrist — with a live dashboard showing your current exercise, sets and wrist-based heart rate. Building workouts, browsing the exercise library and reviewing analytics stay on iPhone.

Wrist heart rate is used only when you start the workout on the Apple Watch. If you start a workout in the iPhone app, the Watch app does not use its heart rate sensor — for iPhone-started workouts, wear AirPods Pro 3 to get live heart rate. To use the wrist sensor instead, start the workout from your Apple Watch (using a workout you've scheduled for today or favourited).

When you start a workout in the iPhone app, Iron Karnet appears on your Lock Screen and in the Dynamic Island — showing your live heart rate, current exercise and set, and a rest timer counting down. Tap Done to log a set, or during rest tap Skip or Water, all without unlocking your phone. It runs alongside your music.

No. The Lock Screen Live Activity and Dynamic Island appear only for workouts you start in the iPhone app. A workout started on the Apple Watch runs on the Watch and does not show an iPhone Live Activity.

With your permission, Iron Karnet reads and writes data to Apple Health — including workouts, weight, water intake, supplements and body measurements. Sync happens automatically in the background, so you never have to enter data twice. You can manage exactly what's shared in iOS Settings → Health → Data Access & Devices.

In the Supplement Manager, tap to add a supplement and choose the scan option. Point your camera at the label and Iron Karnet uses on-device OCR to read the details, which you can then review and save.

Yes. Both the Water Tracking and Supplement modules let you schedule reminder notifications. Make sure notifications are enabled for Iron Karnet in iOS Settings → Notifications.

Yes. New subscribers get 7 days free. You won't be charged if you cancel at least 24 hours before the trial ends — open iOS Settings → tap your name → Subscriptions → Iron Karnet to cancel. If you don't cancel, your chosen plan starts automatically when the trial ends.

Subscriptions are handled through your Apple ID. Open iOS Settings → tap your name → Subscriptions → Iron Karnet to view, change or cancel your plan. Cancelling stops future renewals; access continues until the end of the current billing period.

Make sure your iPhone is signed in to the same Apple ID you subscribed with, then open the subscription screen in Iron Karnet and tap Restore Purchases. Your plan is linked to your Apple ID, so it carries over to a new iPhone or a reinstall. Still stuck? Email us and we'll sort it out.

You can clear data inside each module, and you can revoke Apple Health access at any time in iOS Settings → Health. To request full deletion of any account data, email support@ironkarnet.app.
