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 the most secure email and calendar software that I've been able to find. they have super fast support that got me out of a big jam. Their paid tiers are well worth the money.
MARC DONI
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.
BRYCEN GUNTER
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.
CHRIS L McCLISH
A fantastic app! Privacy is paramount with emails, contacts, and calendar information, which isn't used for advertising. I highly recommend it! The team is available and responsive to any issues, should they arise. Go for it without hesitation!
RAPHAËL CAUHÉPÉ-FRANÇOIS
It's hard to find a service that appeals to both privacy nerds and people who just need to get through their inbox asap, but they've nailed it. My data feels safer and the price is reasonable. I'd love to see them add an encrypted meetings feature in the future. Definitely worth the switch, don't think twice.

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, F-Droid app, Linux app) way better.
JEREMIAH
Green, genuinely cares about open source, and great service. Tuta doesn't depend on Google services at all, unlike others (Proton)
JERRY
Uses 100% renewable energy, 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
A good alternative to the big players like Google/Microsoft if you care about privacy and want something more European.
OLAF VAN DE BELT
Thank you for respecting our privacy, at the same time thanks for being a green energy company.

Ad-free
We give you the freedom to communicate confidentially, without any tracking or personalized ads.
I formerly used Gmail for many years till I just got sick and tired of all the spam and ads. I've been using Tuta for around a year now, and not once have I received spam nor an intrusive ad. Tuta's free plan comes with plenty of space for the average person, and the app is incredibly easy to use. 100% recommend!
KIERAN LEE
Exactly what I was looking for. Independent of Big Tech. Great email program.
NORBERT
Why do I like it? Because the interface is simple and ad-free.
LAURENT OUTAN
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 ought also know that free isn't really free, the price is for tech companies to get your info. I love Tuta.
