I’ve used Joplin for years now before was Evernote. I like it because it’s open source and the syncing option is built in, exemple either to Dropbox or NextCloud (I use both these options, DB only because I have a free option of 12gB otherwise I would use just NC) The syncing is painless as as I said built-in. It’s not a pretty app, fairly plain, but it works perfectly, on my android and Linix PCs, Arch and Debian. I did try Obsidian once. It’s pretty, but not being open source put me of. Try it again, takes minutes to set up, as again open source and works well

I don’t use Trillium, tried once Obsidian but it’s not free. Have you tried Joplin, it’s free works extremely well with Dropbox or NextCloud for syncing between téléphone and the PC. For note taking its extremely good

Diaro sends me a notification and the end of the Day, reminding me to write something.

I keep a diary using Diaro on my android phone. I started a long time ago in note books, but as even I can’t alway read my own writing, switched to typing. I don’t write much, mostly rubbish, what I do find useful is the ability to search and find things, ‘repaired the fridge’ ‘changed the battery in the smoke alarm’, ‘had so and so around for dinner’ , ‘bought this and that’ … It’s only for myself, do when I’m dead and gone it will just disappear like myself

Garmin Epix Pro gen 2, by far the best, as like the 7x but with an OLED screen. A real fitness watch, rather than a apple smart watch
