This planner is so simple but it is exactly what I need. I get many options for time and tasks/events and I see everything in front of me. It is easy to change things around and set the time/day for when i need something set. I honestly really like this planner. I am a busy person but I’m always unorganized or unfocused so this is really helpful.

Wooooooooooooooo0 ,

Nice year view!

Heatmap display in year view is nice!

Sudden malfunction & no app suppprt

I was using my calendar just fine for a few months and then for a couple of days it would tell me “error, can’t modify event.” I tried to find a support page to help me but it would only bring me to the welcome page. Terribly frustrating. Will look for a better calendar app and start over.
