davx5 on phone korganizer on desktop

CalDAV is all you need

I setup Nextcloud and then realised no one used it's Calendar, or contacts, or basically anything - it was just being used as a sync hub for phones.

So, I ditched it for Radicale. Waaay less maintenance.

DAVx5 on the phones with Fossify Calendar & Tasks(.org) apps from FDroid.

They do all the alerting.

On the desktop Vivaldi has a good built-in Calendar, so I use that (although I've only just noticed it doesn't show Tentative appointments at all)

For work, I use Logseq (for everything) & to keep a note of ToDo items that I don't need reminders for (otherwise Tasks is overwhelming)

And for bonus points, Home Assistant has a CalDAV module so domestic things like waste collection are sync'd from Radicale too so there's a notification on the kitchen display each morning to tell me what coloured box, bin, bag needs to be taken out today.

And... (some time management advice thst you didn't ask for) - I'm currently starting timeboxing - so instead of creating a todo item, just schedule the time to actually do it in. Less ToDos, but more progress (I hope)

I use Todoist for tasks/reminders. Works great on Linux for me.

Nextcloud includes caldav.

• linux Gnome with calendar and task app
• android with fossify calendar and jtx board

It may not be the fanciest setup but it just works withiut problems.

Edit: davx5 of course

Android phone.

selfhosted radicale Tasks.org on Android Thunderbird on Computer

I mostly use my phone, Tasks is great! https://play.google.com/store/apps/details?id=org.tasks

I use a paper agenda that I check every day. I also check up the rest of teh week and the month page summary, to get an idea of what's to come.

Gave up on other people's solutions and wrote a giant shell script that does exactly what I want it to do. Calendar, tasks, reminders, everything. This is the promise of free computing! (Well, you did ask.)

I wonder if it is possible to get the calendar in Thunderbird to take appointments from my Android phone's calendar.

I use Trello to organize my life, because every other solutions I've tried aren't enough to keep up in the long run, unfortunately. I even considered developing an open-source clone of it, but never dive into doing it (yet).

I think this might be more of a selfhosting question, so maybe better for that sub.

I use Proton for business since it runs on everything. Zero issues.

Default clock/alarm app in GrapheneOS, or Tuta calendar app (also on GrapheneOS). I don't rely on my desktop or laptop for any reminders since I don't always have one of those running near me, especially not unmuted

You strike me as a user who'd benefit greatly from minimizing tool counts--this is a lot of steps for what a small pocketbook and pen can accomplish.[Also very little can match the pen/paper combo's security levels]

With all that said, I know paper can't grab your attention on its own, for this reason I overlap with tuta calendar (Which should be a reasonable level of security and convenience imho).

When you using that many separate techs, it has to almost feel like the tools themselves require more attention and care than the work you need planned and structured.
