The best apps for a Galaxy Watch 3 are the Samsung companion apps and compatible software you already have: Galaxy Wearable for setup and management, Samsung Health for health and activity tracking, and Samsung Health Monitor for eligible ECG features. Tizen app distribution has ended, so this is not a current app-installation guide: older third-party recommendations may no longer be downloadable, and individual legacy apps may not keep working.
The Galaxy Watch 3 runs Tizen 5.5, not Wear OS. Samsung says distribution of Tizen-based watch apps has been discontinued. Before relying on a legacy app, check whether it is already installed and whether its service still supports the watch.
Quick guide to Galaxy Watch 3 apps
| App | Role | What to know |
|---|---|---|
| Galaxy Wearable | Samsung companion app | Use it for watch setup and management. Phone and feature compatibility can vary. |
| Samsung Health | Samsung health and activity app | Part of Samsung’s wearable ecosystem; available features and behavior may vary by phone and setup. |
| Samsung Health Monitor | Separate health app | Provides ECG functions on compatible Galaxy Watches, subject to device, phone, and regional requirements. |
| Spotify | Legacy third-party app | Spotify documented Tizen support up to Galaxy Watch 3, but this does not establish that new installation is possible or service remains available on every watch. |
| Strava | Discontinued Tizen support | Strava ended Tizen support on November 1, 2025. Do not rely on the watch to record or sync new activities to Strava. |
Start with Samsung’s companion apps
Galaxy Wearable: setup and management
Samsung identifies Galaxy Wearable as the key app for using a Galaxy Watch. It is the starting point for pairing and managing the watch with a compatible phone. Check Samsung’s compatibility information for your phone and region rather than assuming every feature works on every device.
Samsung Health: health and activity
Samsung Health is Samsung’s health and activity app for its wearable ecosystem. Use it for the health and activity features supported by your Watch 3 and phone combination. Do not assume that the same features or data behavior are available on every phone.

Samsung Health Monitor: check eligibility first
Samsung Health Monitor is separate from Samsung Health and enables ECG functions on compatible Galaxy Watches. Setup and availability depend on device, phone, and region. Check Samsung’s eligibility guidance before expecting the feature to be available. Samsung cautions that ECG is not intended for people under 22 or for people with known arrhythmias other than atrial fibrillation, and it does not replace diagnosis or treatment.
Legacy third-party apps: check before relying on them
Spotify: documented support, but treat it as legacy
Spotify’s support information lists Samsung Tizen watches through the Galaxy Watch 3 and describes controls for music, podcasts, and audiobooks. It also documents Premium downloads for playlists and albums, plus text search; features can vary by model. However, Samsung has ended Tizen app distribution, and Spotify says Tizen watch support has ended. Treat Spotify as a legacy app, not a guaranteed new download or continuing service. If it is already installed, verify its behavior on your own watch and phone.

Strava: no longer a Watch 3 recording option
Strava ended Tizen support effective November 1, 2025. After that cutoff, users cannot record activities directly on a Tizen watch or sync new activities from it. Existing Strava account data remains available, but the Galaxy Watch 3 should not be recommended as a current Strava recording device.
Can I still download apps for Galaxy Watch 3?
Do not assume you can install an app from an old recommendation list. Samsung discontinued Tizen watch-app distribution in Galaxy Store. Samsung Galaxy Store support said the Tizen watch content service ended June 25, 2025; previously purchased content could be downloaded through My Apps on supported devices until September 30, 2025. Those dates have passed, and availability for a particular app or device should not be assumed.

Galaxy Watch 4 and newer watches use Wear OS, with watch apps distributed through Google Play. Those apps are not Watch 3 apps and should not be treated as compatible with this Tizen watch.
How to choose apps you already have
- Check whether the app is already installed on the watch or appears in your supported purchase history. Do not rely on an old article as proof it can still be downloaded.
- Check the app maker’s current support information for Galaxy Watch 3 or Tizen. A historic compatibility listing does not guarantee current service.
- Confirm the phone, region, subscription, and model requirements. Spotify’s documented offline downloads, for example, require Premium and may vary by model.
- Test the feature you need on your own watch before depending on it for a workout, route, payment, or other important task.
