We recommend publishing an updated iOS and Android app at least once per year to account for general performance improvements, bug fixes, and to make sure your app functions as expected for all users on the latest iOS and Android software and devices.

However, there are also specific events that may make an app update more urgent:

Major iOS & Android software releases

• Major operating system releases, such as iOS 17 and Android 14, include significant changes that may affect your app’s core functionality, user interface, and performance.
• We recommend publishing an updated version of your app when a new iOS/Android version is released to ensure compatibility.
• You can read about iOS upgrades here and Android updates here

New Apple device launches

• New Apple devices often ship with new functionality or significant design changes. For example new biometric hardware, new screen sizes, NFC capabilities, etc.
• We recommend that you publish an iOS update when new device models are launched. This ensures your app is fully compatible with the latest devices and your users don’t face issues when they upgrade. ‍

Adding native functionality within Median’s App Studio‍

• You will need to publish an update for your app if you are using Median’s App Studio to change or add native functionality. This includes adding a new native plugin or editing native features within the App Studio (website overrides, branding, native navigation).
• Some native functionality, such as native navigation and link handling rules, can be changed dynamically at runtime using the Median JavaScript Bridge. While you can always publish a new version with the configuration changes embedded, making use of the JavaScript Bridge will avoid the need to publish an app update. For more information on the JavaScript Bridge, see here‍
• All changes to your web content flow to your app automatically and do not require an update. 

Step 1: Make any required changes to your app in the App Studio and preview your apps in the browser-based mobile device simulators to verify basic functionality.

Step 2: Create a new iOS and/or Android build as required on the Build & Download tab, then click “Rebuild all”. This will rebuild your app with the latest iOS & Android source code.

Step 3: Publish your updated app

• Once your app is rebuilt you will need to download the iOS and Android files and publish an update to the Apple App Store & Google Play Store. Need help publishing your update? Median offers an App Update Publishing service which can be purchased on the "Services" tab.
• If you purchase our app update publishing service we can also update your developer account & OneSignal certificates.
  • Users with a Support & Updates plan can access priority email support from our engineering team by clicking the chat bubble on the bottom right within the app studio (circled in the screenshot below).
