Comparison of best free calendar apps
Free, widely used and with an extensive set of features, the calendars from Google, Microsoft and Apple make planning your events ever so easy. So does Tuta. The encrypted email and calendar service also makes sure that no one can spy on your business meetings and personal events. For the first time, you can host your calendar online and be sure that no one but yourself can see your doctor's appointments or any other sensitive data in your calendar.
What makes a good calendar app?
Apart from security and privacy, which to our understanding is a basic necessity, the most important need that a calendar has to fulfill is to help people get organized. Being able to schedule appointments (also with others), to add repeating events, to receive notifications about important events, and to look up birthdays are some of the most important features people need from calendar apps.
Before comparing calendar apps, we narrowed down the ones we wanted to include in this comparison to the mostly used calendars: Google Calendar, Outlook Calendar, iCloud / Apple Calendar and Tuta Calendar. For the comparison, we focused on the following: A calendar app must be easy to use, well and functionally designed, enable users to send out invites and to share entire calendars. The calendar should also be available on all devices including browsers, desktops, smartphones and tablets so that you can keep track of upcoming events wherever you are.

A better web
Secure
Tuta automatically encrypts all your data end-to-end with post-quantum cryptography which makes it the safest email provider.
This is hands down the best free privacy oriented email service out there. They genuinely care about the end users privacy. The data they collect is next to nothing (if any) and provide a plethora of amazing services.

Secure email and a secure calendar. I didn't need 20gb of space but I wanted to pay to support this company. I also enjoyed the ability to have custom domain integration.

Best secure Email provider! Love this provider! I've been a happy customer for a while now. I have even recommended this to relatives. No worrying about privacy infringement or identity/data security. I can rest assured that my emails remain private.
TRISH
For this Android user, this secure email client is one of the best available out there. I like having the calendar, email and contacts combined in one app rather than multiple places. Great app for those important emails and events.

Green
We take our responsibility seriously and only use renewable energy to power your emails, calendars, and contacts.
Thanks for being a solid company, I'm very happy to have switched from proton since Tuta handles several things (green energy, fdroid app, linux app) way better.
JEREMIAH
Uses 100% renewable energies, open source, supports non-profits and schools, respects privacy, ad-free. Also offers nice phone and laptop apps. Just switched to a paid account to support the company though the free version is really good already on its own (I've used it for a year now). Definitely five stars!
TARKAN SCHNEIDER
Ad-free
We give you the freedom to communicate confidentially, without any tracking or personalized ads.
It works very well and you are not bombarded with intrusive and harmful advertising. A most excellent replacement for all Microsoft and Google email accounts!
ANONYMOUS
Secure and private with encryption, ad free and free, what's not to like.
GRIMEST
Tuta is the best cost-benefit email service in the market. It has the same main features as most mail providers. The difference is that Tuta cares about your privacy and won't use your data against you, nor try to convince you to click on ads selling stuff you don't need.
FERNANDO SILVA
With the big tech companies scanning and using your email as a way to push advertisements, it's comforting to use something secure and, for lack of a better word, cool. You use email a lot right? You out also know that free isn't really free, the price is for tech companies to get your info. I love Tuta.

I use Tuta 2 weeks now and I didn't find something to keep me away. Black beautiful GUI, easy to navigate throughout app, encrypted messages with password, even the login has 2FA, there is no ads.
