From our experience, it might take anywhere between 2 and 12 weeks to launch an App depending how ready you are.
Here is an example of an App launch timeline:
Gather creative assets for the App demo for Disciple to build.
Review the demo and finalise the App. Learn how to use CMS.
Upload content, set up Developer Accounts and work out Data Protection framework. Finilise and prep App's launch content.
When you're ready to go, we'll submit your app to the App Stores for approval. This is unfortunately out of our control but typically takes around 24- 48 hours for iOS (App Store). You can read more about the review process for Apple here.
