What you actually did. The thin mark is what you planned.
A new week arrives with this shape already on it. Move things around inside a week as much as you like, the template underneath does not change.
There is no save button. Every change is kept the moment you make it, and on the published page it is kept on the server, so your phone and your Mac show the same week. The button below is only for taking a backup file away with you.
Your week lives on the server so it is the same on every device. Put your email in and I will send you a link to sign in. No password.
