Hi. I've created this Android app for a couple of motivations: 1. no need to sync; 2. easy to throw away (no lock-in); 3. works without internet access.
The app runs a small web server and allows you to edit your journal with the app UI, and also from browsers on other devices. Since in both cases the changes will be persisted in the phone, no need to sync.
You can connect to the editor server by using a private IP address in the local network, Tailscale network, or optionally, use a built-in HTTPS tunnel (paid subscription) via the internet and keep a handy access with the same URL.
I'd appreciate your feedback. Thanks!
