Hi! I understand you're having trouble finding the Tubidy FM Offline Music Player app in your App Store. To help you better, could you share which country or region your Apple ID is set to? Sometimes apps are not available in certain regions due to licensing or distribution restrictions.

Meanwhile, here are some common reasons why the app might not be visible in your App Store:

1. Regional Availability: The app may not be available in your country’s App Store. For example, some users from regions like Zambia have reported not seeing the app because it's restricted1 8.

2. iOS Version Compatibility: Make sure your iPhone’s iOS version (you mentioned 16.7.11) is compatible with the app. Usually, this isn't a problem with recent versions unless the app has specific requirements.

3. App Removed or Temporarily Unavailable: Occasionally, apps may be taken down by developers or Apple due to updates, policy changes, or technical issues. There have been some reports that Tubidy FM was removed or had limited availability on iOS3.

Here are a few steps you can try:

- Verify your Apple ID region settings. If it's set to a country where the app is not available, you may consider switching regions temporarily if you’re comfortable with that.
- Check for any restrictions on your device (Settings > Screen Time > Content & Privacy Restrictions > iTunes & App Store Purchases) that might prevent app downloads.
- Restart your device and try searching again in the App Store.
- If you previously downloaded the app, check your purchase history or the "Purchased" tab in the App Store app.

Could you try these and let me know if it helps? If the app is not available in your region, we can explore possible workarounds or alternative apps for offline music playback.
