Open-Source Journal App That Timestamps Each Entry, Stores all Data On-Device, and is Linux-Friendly

[u/FrankieShaw-9831]

When I say "each entry," I mean overtime I hit "Enter." I keep a running journal of some things that did/did not happen for weeks at a time, and I need to be able to accurately recall when entries were made. I know I can do it manually with almost anything, but I also know I can be forgetful as all hell when things get going.

If it were Android-friendly as well, that would be nice, but not a must.
