How do I activate the Pro version on other devices?

Using the same operating system

To activate your purchase on another device with the same operating system (e.g. Android → Android or iPhone → iPhone), please follow these steps:

👉 Open the Pro version payment screen

👉 Tap on “Already a Pro user? Restore purchase”

The app will automatically check whether your purchase is linked to your Google account (Android) or Apple ID (iOS).

👉 Important:

You must be logged in with the same store account that was used to make the purchase.

This is what the restore button looks like:

 Using multiple devices & sharing with family (Version 4.0)

With the current version 4.0, you can use your Pro version across multiple devices and share it within your household.

👉 How it works:

• Log in on all devices using the same email address in the app

• Use the same login details that you used when activating Pro

👉 Your Pro version will then be automatically unlocked on the other device.

In addition, you can now create multiple profiles within the app.

👉 This allows you to:

• set up different people (e.g. partner or family members)

• store individual intolerances for each profile

• instantly see what is suitable for whom when scanning or searching
