Whistle PRO Support

The Apple Watch and Wear OS app for football referees

Frequently asked questions

Which devices are supported?

iPhone with iOS 17 or later and Apple Watch with watchOS 10 or later, or an Android phone with Android 8.0 or later and a Wear OS 3 or later watch (such as Galaxy Watch4 and newer). The phone and watch must be from the same side: iPhone with a Wear OS watch, or an Android phone with Apple Watch, is not supported.

How do I install the watch app?

After installing Whistle PRO on your iPhone, open the Apple Watch app on iPhone, tap My Watch > Apps, then tap Install next to Whistle PRO under Available Apps. You can also install it directly from the App Store on Apple Watch.

How do I install it on a Wear OS watch?

Install Whistle PRO on your Android phone and tap Install on watch on the app's start screen; the Play Store opens on your watch. Tap Install on the watch, then tap Check again in the phone app. You can also search for Whistle PRO in the Play Store on your watch.

Do I need my phone during a match?

No. The whole match runs on the watch alone. When the match is over and your phone is nearby, the record is transferred automatically.

What is free?

The match timer, added time and haptic alerts are free, with no subscription. Event logging (goals, cards, substitutions), workout data (heart rate, distance, sprints, heatmap), match reports and match history are part of the PRO subscription.

How do I subscribe or cancel?

Start a monthly or yearly subscription in the iPhone app under Settings > Whistle PRO. The first week is free. To cancel, go to iPhone Settings > Apple Account > Subscriptions > Whistle PRO. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period.

On Android, subscribe in the phone app's Settings. To cancel, tap Manage subscription in Settings, or go to Play Store > profile > Payments & subscriptions > Subscriptions.

I switched to a new iPhone and lost PRO.

Tap Restore purchases in the iPhone app's Settings. Make sure you are signed in with the same Apple Account you subscribed with. Apple Watch picks up the change shortly after. On Android, sign in with the Google account you subscribed with and tap Restore purchases in Settings.

Heart rate or distance is not recorded.

Check that access is allowed in the Health app on iPhone > Summary > your profile picture (top right) > Privacy > Apps > Whistle PRO. On Android, turn on Save workouts to Health Connect in the app's Settings and allow the Health Connect permissions. Workout data is a PRO feature.

The heatmap or sprints are empty.

Make sure Record GPS is turned on in your match preset and that location access is allowed on your watch. GPS is used only during match time.

Where are my matches stored?

Only on your watch and phone. Nothing is sent to a developer server. Deleting the app also deletes its records, so share a report for any match you want to keep. See the Privacy Policy for details.
