To purchase, install, and run Things, your device must be running a supported OS (Operating System).
These are the minimum requirements for Things:
- Mac: macOS 10.13 or later
- iPad: iPadOS 12.1 or later
- iPhone: iOS 12.1 or later
- Apple Watch: watchOS 5 or later
If your device is an older model, it might not be able to run a supported OS version. As a result, you won’t be able to purchase Things. If you already purchased Things in the past, but now cannot update to a newer OS version, you can continue using the last version of Things that worked on your OS – but you won’t receive updates or new features until you upgrade to a modern device.
To check your OS version – and update it, if possible – please see this page.
