Dear Purple DS users,

we appreciate that you built your demo-app with our Purple DS® Manager. Apple asking all iOS developers and users to hold a valid certificate. These need to be updated yearly and SPRYLAB is taking care of this matter for you. So no need to go through the hassle of getting a certificate yourself for your demo-app.
We renewed our iOS certificates.


After a simple four step approach your iOS demo-app is ready to use just as before! No need to delete your app currently on your device – the app will be replaced automatically. Your previous content and layout will not be affected.

Please login in the Purple DS® Manager  ( and follow the steps:

  1. Open your app
  2. Press „Build App“
  3. Choose the iOS platform and press "build" – this will start the update of your iOS certificate
  4. As soon as the "app creation" is complete (see progress bars close to the app icon), you can download your app and re-install. This may take a few minutes.

Done. :-)

If you have questions, please get in touch with us.
We wish you a lot of fun with your demo-app!

Your SPRYLAB Customer Care Team
