A hub of written thoughts in fast searchable plain text
About this app
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. * 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 * Permission to access network as MathJax is used for math rendering. MathJax will be cached for offline rendering later. * Permission to receive boot completion for Tasker to schedule backup requests on legacy devices (pre-Android 8.0). It has no effect on devices running later versions of Android.
1. and 2. can be denied/revoked as needed either from Settings or via Marshmallow's runtime permissions.

Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.appmindlab.nano is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 4.6.3 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall neutriNote CE first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of neutriNote CE, and a listing is removed when the evidence for it stops holding up.
