Ratings and reviews

Not what I expected from a pay for service. Considering the massive amount of time it takes to open a new calendar I am very disappointed in Tuta as a paid for service. The biggest problem is missing entries into the calendar and when I save certian events under one color it changes to another color causing schedule confusion and planning errors. If I could share a color blue to save it shows up as brown when viewing.

If having all events/appointments one color is OK then the free version can work. And, startup time after closing the app' is interestingly sluggish, but left running it's up quick. To get color variety for types of events the fee is roughly 36€ a year, because color options only come with multiple calendars, which are past the pay-wall. Nope, not bothered enough by free options yet. Cheers.

I really like it when it's working, but it has many bugs. The widget is barely usable: it keeps syncing most of the time and while syncing it does nothing at all, just goes blank for minutes and shows only an animation, not even today's date, nor does it open the main app when touched. Events disappear, I re-enter them and then they are duplicated. Please make more in-house testing before asking customers to report problems.
