Support & FAQ

Work through these in order:

1. Check your Apple Watch fit. A loose Watch can prevent the HR sensor from locking on. Make sure it's snug on your wrist before starting a session.
2. Verify all Health permissions are enabled. Open the Health app on your iPhone, tap the circle with your initials or photo in the top-right corner, then go to Privacy → Apps → Tera 7.83. Confirm that Heart Rate (Read and Write) and Workouts are all turned on. If any are off, enable them and start a new session.
3. HR data from the first 15–30 seconds is normal to be missing. The Watch sensor takes a moment to lock on — see the question below for details.

You can also re-enable Health access from inside the app: tap the Health Permissions Needed banner on the home screen if it appears, or go to Settings → Enable Advanced Tracking.

Permissions can be accidentally turned off if you tapped "Maybe Later" during Premium setup, or toggled a permission off in the Health app.

Apple Watch HR monitoring typically takes 15–30 seconds to start after a session begins. The sensor needs a moment to lock on, and the Watch app needs to establish a connection with your iPhone.

For best results, put your Watch on and make sure it's snug before starting a session. HR tracking will begin automatically — you don't need to do anything on the Watch.

If you notice a longer delay (over a minute) on the very first session after installing or reinstalling the app, that is normal. The Watch app re-establishes its connection after a fresh install, and subsequent sessions return to the usual startup time.

Check the following:

1. Make sure the Tera 7.83 Watch app is installed. When you install Tera 7.83 on your iPhone, the Watch app is queued for download. Your Watch may prompt you to install it — tap the prompt on your Watch to complete the install. You can also open the Watch app on your iPhone → App Store tab and install it from there.
2. Your Watch is worn and unlocked before you start a session.
3. Heart Rate permissions are enabled — see the first question above.

The Watch app launches automatically when you start a session. You don't need to open it manually.

This is usually caused by low storage on the iPhone, not the Watch. iOS needs free space on the iPhone to prepare a Watch app before it can hand it off, so if your iPhone is nearly full, the Watch app can silently fail to install — even with plenty of room on the Watch itself.

To fix it, free up space on the iPhone: go to Settings → General → iPhone Storage and offload or delete some apps. Once there's enough free space, open the Watch app on your iPhone and Tera 7.83 (along with any other pending Watch apps) should install automatically within a few minutes.

Yes. The binaural audio, haptic pulse, and all three session phases work on iPhone alone. Apple Watch adds real-time heart rate tracking and the HR trend charts — those features require Premium and a paired Watch.

Session history syncs via iCloud. After reinstalling, open the app and wait 1–2 minutes — your sessions will reappear automatically as long as you're signed into the same Apple ID.

If sessions don't appear after a few minutes, check that iCloud is enabled: iPhone Settings → [your name] → iCloud, and make sure Tera 7.83 is listed and turned on.

Both devices must be signed into the same Apple ID with iCloud enabled. Sync can take a minute or two after the app launches. Make sure you're not in Airplane Mode.

Open the app, go to Settings → Restore Purchases. This relinks your purchase to the current install. If the issue persists, make sure you're signed into the same Apple ID used to make the original purchase.

Yes. Premium is a one-time purchase tied to your Apple ID — not a subscription. Use Restore Purchases on any device signed into the same account.

No. Premium is a single one-time payment. You pay once and own it forever, including all future updates to the Premium feature set.

Your instructor gives you a 6-character invite code. Sign up in the app as a student, then enter the code when asked. You are then on your instructor’s roster and can see your lessons, homework, messages and videos.

On the sign-in screen tap Forgot password?, enter your email, and the app sends a 6-digit code from “Pro Golf Coach” (no-reply@jms-solutions.biz). Type the code in the app and choose a new password.

If the email does not arrive within a couple of minutes, check your Junk folder, and add that address to your Contacts so the next one lands in your inbox.

1. Open Settings, then Notifications, then Pro Golf Coach, and turn on Allow Notifications with Lock Screen and Banners ticked.
2. Check that a Focus (Do Not Disturb, Sleep) is not silencing the app.
3. Make sure you are signed in, online, and on the newest version of the app.

The Device Settings Guide has the full checklist.

iOS is hiding the text while the phone is locked. Open Settings, then Notifications, then Pro Golf Coach, then Show Previews, and choose Always (or When Unlocked to read it after Face ID).

Open times refresh when you open the app, when you change your calendar, and in the background. The circular-arrow button at the top right of Calendar & Availability refreshes them on the spot.

For background refresh, turn on Settings, then General, then Background App Refresh for Pro Golf Coach, and do not swipe the app away in the app switcher.

Instructors: Lesson Bookings, swipe the lesson left, tap Cancel, then Cancel Lesson. The time reopens and the lesson leaves your calendar.

Students: Book a Lesson, then My Upcoming Lessons, then cancel the lesson.

The other person is sent a message automatically. Deleting a lesson from your own calendar does not cancel it; cancel in the app, then delete it from your calendar too.

A video can be up to 45 seconds long and 50 MB. Pick it from your photo library inside the app; the app only sees the videos you choose. Trim a longer clip in the Photos app first.

Delete my account: Account, then Danger Zone, then Delete My Account. An instructor must remove all students first.

Remove a student (instructors): the student moves to Recently Removed and can be restored for 14 days; after that the student’s records are permanently deleted.
