Soverin works with the Mail app on my computer and phone, and is fast. I use it for all my personal domains, because there's no limit to the number of aliases an account can have. My family can use it too, for just 5 Euro per extra mailbox.

For sensitive chats and private communication I trust Threema's audited encryption to keep my data safe.

iMessage works with my computer and my phone and is free and relatively secure. For day-to-day encryption iMessage is my go to.

I use this for notes during classes and to keep personal projects organized. It's tagging feature is super useful to keep things organized without spending tons of time splitting notes between folders or notebooks like you do in other apps.

There are tons of password managers out there but there are lots of little things that make the $2.99/month well worth it to me. The Watchtower feature has saved me more than I'd like to admit, and the app's built in password strength warnings help me get my online security up to scratch. Travel mode is great for passwords and data you simply cannot afford to lose.

It hooks into Finder seamlessly and works in the background. Other cloud storage services may cost less or have prettier interfaces, but I never see or worry about my iCloud backups. They just work.
