The app looks very promising. I love the widget with the time tracker on it! This helps me a lot. However, the 7 day overview does not show you anything, as it’s too crammed.
But.. the price is very high, so I’m not sure if I’ll buy the premium after the trial. I’m already using Todoist and love the integration, but €70+ €50 is a lot of money for some tasks and planning - where I feel Todoist gives you more for your money. In comparison to the standard calendar app, I’m mainly interested in the time tracker widget (not worth €70).
