2. Click on the Apple ID icon in the upper-left corner (the one with your name and image)
3. Click on iCloud
4. Click the "Show More Apps…" button
5. Scroll the list until you find MindNode and make sure the toggle is switched on

iOS

5. Scroll the list until you find MindNode and make sure the toggle is switched on

III. Sign up for MindNode Account

MindNode Account is our optional account system that enhances our MindNode Plus subscription. Previously, to share our subscription between your devices, you needed an iCloud account. Using MindNode Account, you can now access your subscription from devices that do not use iCloud (e.g., devices owned by a company or personal devices using different Apple IDs). Learn more here.
