DesignsTouch is using the Apple Developer Enterprise Program to create and distribute test Early Adopter version of Racine App for distribution during pre release phase. You must establish trust for these apps before you can open them.
To manually install the pre-release version of the app, you must also manually establish trust. When you first open an enterprise app that you’ve manually installed, you see a notification that the DesignsTouch isn’t trusted on your device. You can dismiss this message, but then you can’t open the app.
After you dismiss this message, you can establish trust for DesignsTouch. Tap Settings > General > Profiles or Profiles & Device Management. Under the “Enterprise App” heading, you see a profile for DesignsTouch
Tap the DesignsTouch profile under the Enterprise App heading to establish trust for this developer.
Then you see a prompt to confirm your choice. After you trust this profile, you can manually install other apps from the same developer and open them immediately. This developer remains trusted until you use the Delete App button to remove all apps from the developer.
You must be connected to the Internet to verify the app developer’s certificate when establishing trust. If you’re behind a firewall, make sure that it’s configured to allow connections to https://ppq.apple.com. If you aren’t connected to the Internet when you trust an app, the device displays “Not Verified” instead. To use the app, connect to the Internet and tap the Verify App button.
After you verify an app for the first time, your iPhone, iPad, or iPod touch must reverify the app developer’s certificate periodically to maintain trust. If you can’t reverify, you may see a message that verification will expire soon. To maintain trust, connect your device to the Internet, then tap the Verify App button or launch the app.
