We regularly help customers - that already have an app - switch to an app created by us. There can be many reasons for this. The most common ones we hear are:
- the existing app is outdated
- the existing app contains bugs that can't easily be fixed
- they no longer want to separately maintain both their website and app
It's always great if you let us know what your reason is, so we can make sure that we can fulfill your expectations.
How it works
Android (Google Play Store etc.)
To publish your app as an update, the new app needs to have the same digital signature as the old app. For that, you will need the following information:
- Your keystore. Usually a file with the file type .jks
- Your key password (keypass)
- Your keystore password (storepass)
- Your key alias
You will be able to upload the key information in our app publishing guides.
If you'd rather sign your app yourself (which is more complicated), see our guide on signing app bundles yourself. You can skip the section about generating keys, as you need to use your existing ones.
Apple App Store
We also support updating/replacing existing iOS apps. You don't need anything specific in advance here except access to your Apple Developer account where the app is published.
Our app publishing guides will lead you through all the necessary steps to update your app.
