Ratings and reviews

I really like this calendar, and I even paid for the Windows premium version. I'm a little bummed that I missed the early access for "One Task" for Android because I like how they work together in Windows. i guess I'll keep checking the Play store for it to become available. These developers seem to be doing great things, and I'm looking forward to seeing what else they're working on.

Just went up a star!!! Thank you for syncing with Outlook calendar! I've had Google calendar and Samsung calendar lose all my appointments in the past so I went to Outlook. There's very few other simple/basic calendars that sync with it ( most require having the Outlook app on the phone) Still can't import or export ics though. Add that and I'll go up another star 😁

I think the app could be good, if it had an option for local only. I don't want to have to sign into and connect to another calendar service just to use a calendar. Make an option to be able to set a appointments without forcing you to connect to a separate internet calendar (that I could just download instead because all of them have their own apps) and this would be a great app.
