# 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
