I assume you tried using Joplin as a to-do list app? IIRC it worked, but was too fiddly with the square brackets.

Tasks.org is an open-source to-do list app working with multiple providers. On first glance, CalDAV and EteSync might be something for you (ignore DAVx⁵ as it’s a worse CalDAV).

As for me I’m using CalDAV my mail provider mailbox.org is providing me together with Tasks.org on Android and Thunderbird on desktop.

For first few seconds, I deadass though they are talking about Germans with a height of 1,5 meters.

What about boolean though? /s

Do your services need to be reachable from outside right from the start? If not, get yourself comfortable with hosting, maintaning and backing up the server. Automate your backups as much as possible and recover at least once from a full backup to check everything!

This should give you a solid baseline to then think about exposing your services, which is arguably the scariest part, but can come afterwards.

No recommendation or experience, but rather thank you for introducing me to kitchen scales with kinetic energy! This is such a great invention, I didn’t know exists.

I looked into the first brand I found for this, called CASO. Based on Amazon reviews and pictures, I would get the Kitchen EcoMaster for myself. But as said no recommendation or experience!

Quad9 does also offer DoT and DoH.

PairDrop is a fork of SnapDrop, which at one point had more features and active development. Don’t know, how it is nowadays though.

Honourable mention of Léon - The URL Cleaner, which targets the same use-case.Yet URLCheck seems more advanced on first glance.

Thanks for the recommendation!

I can recommend you ICSx5 for ical subscription and DAVx5 for calendar synchronisation.

Yet I would agree, that a good calendar app should ship with these features.
