Type a task, tick it off, get on with your day. Your tasks live in your own iCloud — there is no account to create and no server in the middle.
For Mac, iPhone and iPad. Coming to the App Store.
Everything is stored on your device and synced through your own private iCloud database. Tasks you add on the Mac are on your iPhone, and the other way round. Edits made offline queue up and sync when you reconnect.
We cannot see your tasks. Apple gives developers no access to anyone's private iCloud data, so your list is yours alone.
No analytics, no crash reporting services, no advertising, no tracking. The only network request that isn't iCloud is the optional daily background photo, and it sends nothing about you or your tasks. See the privacy policy for the details.
