If the Speedtest app is not downloading on your iPad running iOS 15, try these troubleshooting steps:

- Check your internet connection: Make sure you're connected to Wi-Fi and that the connection is stable1.
- Restart your iPad: Sometimes a simple restart can resolve download issues5.
- Ensure enough storage: Confirm you have sufficient free space on your device.
- Update payment information: Even free apps may require a valid payment method on file5.
- Prioritize the download: On your Home Screen, touch and hold the app icon (if it appears faded), then tap "Prioritize Download"5.
- Update iOS if possible: If you can update to a newer version (iOS 15 is several years old), check for updates in Settings > General > Software Update.
- Check App Store restrictions: Ensure you have not restricted app downloads in Screen Time or parental controls.
- Try downloading another app: This will help determine if the issue is specific to Speedtest or affects other downloads as well45.
- Clear App Store cache: Open the App Store and tap any of the bottom icons (Today, Games, Apps, etc.) ten times in quick succession to refresh the store.

If none of these steps resolve the issue, you can use the Speedtest website through Safari as an alternative: visit speedtest.net and run the test directly in your browser18.

If app downloads continue to fail, Apple recommends reviewing their support article for more solutions, including signing out and back into your Apple ID, checking Date & Time settings, or contacting Apple Support if the problem persists5.
