I am using Standard Notes currently but I don’t want to pay 10$/month anymore.
**Edit: Guys thank you all for your suggestions. Unfortunately I couldn’t find a one-size-fits-all approach like Google Keep or Apple Notes. I realized that we really dont have much choice as an open source community.
I decided to close my Standard Notes account and started using Gnome Text Editor (it does more than you think) with Syncthing. I am using Markor on my Android end. But it is not really a reliable solution since Syncthing consumes more battery than your average notes app and its GTK client is cumbersome. So even though my quest will continue, I am done for now.**
I used Joplin for a while but it kept giving me these weird errors when writing accents (half my notes are in Spanish…), so I switched over to Zettlr. It’s now where I take notes for everything.
However, those notes haven’t been synced between devices because I haven’t successfully set up my Nextcloud server in my Raspberry Pi. That’s why whenever I need synced notes, I still use my phone’s default note app, since it syncs automatically…
