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

App Permissions Explained:

* Location access for location based search, location stamps, etc.
* Camera access for built-in barcode scanner.
* Storage access for core functions.
* Permission required by Sony devices to avoid crashes on certain models
