What is neutriNote?

In a nutshell, all-in-one preservation of written thoughts, be those text, math (LaTeX), rich markdown, drawings, etc., in fully searchable plain text (universal UTF-8).

Uncluttered UI

Fine-tuned user interface elements to reduce app switching. Accessible search filters for precise navigation to your note contents with minimum taps.


Your workflow can be further automated by Tasker, Barcode Scanner, ColorDict, and other add-ons, or by connecting neutriNote's repository to web-based services. Options available to deep configure your note taking process.


Multiple ways to backup your notes. Freedom to pick a cloud backend that works for you: open source P2P Syncthing, Dropbox, or third party Google Drive, Box, OneDrive components.


Totally free. No hidden permission (see below). Optional add-ons can be purchased to support its development.

after searching 10 apps I think I've found what I need, but the app advertises syncing to cloud such as Dropbox while I can't find any option for that in the app. I'd like to set a path in my Dropbox as the default root path for all my notes. Please let me know where I can sync to Dropbox. Thanks. (P.S.: Also I hate the icon animation when I come out of a note). P.S.: Okay I installed syncthing, really a bad idea, but anyway, now the plus button for adding a local repository path doesn't work.

Hi, this app is designed to work with third party sync methods. For syncing to cloud, please use FolderSync or other dedicated sync apps. Local repo path is restricted by Android 10 OS. Hope this helps.

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.

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.
