Does it work on beta versions of iOS or macOS?

Application does not support beta versions of iOS and macOS. It is not recommended to use the app with the beta versions of systems since there might be various issues with the iCloud syncing.

However most of users using beta versions reported no synchronisation issues. Please make sure to keep your systems up to date and please use the latest versions of Purple Notes app since they contain important changes and fixes in order to support the latest versions of iOS, macOS and watchOS.
