Really good so far, I put a few notes up and I like the way it looks, easy to use and setup. Early days as I look to make new notes, but I love open source because open source just works and it's a lot better than proprietary software. Thank you for a good app.

This app is everything I was looking for past one month! The auto backup option to SD card is brilliant. Though the app looks hideous. Need much more work on the app design which includes the app icon. Need clean, minimalistic and modern look and colour schemes. The blue colour looks awful. Secondly, I hate the fact that the lower toolbar shows up by default. I would rather prefer a clean window but an option to turn it on for those who actually use it.

Thank you for your feedback. Admittedly the code base is getting really old, so there have been considerations to better sustain and modernize the project by open sourcing it.

This app is loaded with functionality - way beyond what I would ever use. Beware that the help file was written originally with Android 10 or earlier in mind. Reference is made to setting the repository when installing. Ignore this if you have a recent Android version. Create a folder called Backup with a sub folder called mirror and enable Backup Mirroring to enable access to copies of your original text files.

Mirror sync will take place when the app goes to the background, or when the user pulls to refresh.
