Open the app, go to Settings, tap Unlock next to Upgrade to Premium, then tap Restore Purchases at the bottom of the paywall. Your subscription will be restored automatically if it's still active.
Subscriptions are managed through Apple. Go to Settings on your iPhone > tap your name > Subscriptions > select KanGym > Cancel Subscription. You can also access this from within the app under Settings > Manage subscription.
Go to Settings > Export backup. Your data will be saved as a JSON file that you can store in Files, iCloud, or share via AirDrop.
Tap Restore backup on the welcome screen or, as long as no workouts are saved yet, under Settings > Restore backup, and select the JSON file you previously exported. Your exercises, workouts, and plans will be restored. If the app already contains workouts, reset it first under Settings > Reset app — a backup replaces the content, it is not merged.
Make sure notifications are enabled for KanGym in your iPhone's Settings > Notifications > KanGym. Also check that your phone is not in Silent Mode (the switch on the side of your iPhone). With AirPods, iOS may read the notification aloud instead of playing the sound (Settings > Notifications > Announce Notifications); with Apple Watch, the watch taps your wrist.
KanGym stores all data locally on your device. If you delete the app, your data is removed. To prevent this, export a backup before uninstalling. If you had a backup file, you can import it after reinstalling.
On the 1st of every month, KanGym sums up your last month as a short story: workouts, volume moved, records, your biggest jump, consistency and your favorite exercise – ending in an image you can share. It sits at the top of the Workout tab for a week and stays in the Progress tab under Recaps. It appears from 4 workouts a month and is free. You can turn off the notification on the 1st under Settings > Monthly recap.
Start your workout on the iPhone as usual and open KanGym on the watch. It shows the current exercise with weight and reps; change them with the Digital Crown and confirm with Done. Your rest runs on your wrist (−15 / +15 / skip), with heart rate and calories. The workout is saved once to Apple Health. The watch app is free and needs your iPhone nearby.
During the workout: long-press the set and choose Edit set. Its numbers stay in the fields – change them and confirm again. After the workout you can delete a set under Exercises > exercise > History > Edit.
Yes. Open the workout in the History tab and tap the note – or Add note if there is none yet.
