Reviews for Tuta: Secure Private Calendar
Happidayz17
Love the privacy and like the usability, needs some tweaks and more customizability.
I really like Tuta!! I made the switch recently from Apple Calendar and Google. Love that it updates on all my devices while remaining private and secure. The calendar app could use some UI changes for more customizability. A setting for default appointment length would be great. Almost all my appointments are 1 hr long, but the default is 30 minutes. This gets a bit annoying. I would also like the option to color code an appointment on the same calendar. As of right now, I’d have to use a second calendar to get a different color for an appointment. Otherwise, love the app and am waiting on tender hooks for new UI/UX updates. Thanks all!
