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.
- and 2. can be denied/revoked as needed either from Settings or via Marshmallow's runtime permissions.

WhatsNew:
v4.5.7
- Optimization for low end devices
- UI adaptive to smaller screens
Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).

library to reduce the number of nested views needed.
- Coordinatorlayout (UI Component)
AndroidX library to position top-level application widgets, such as AppBarLayout and FloatingActionButton.
- Androidx Core (Utility)
a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.

a library to build interactive settings screens without needing to interact with device storage or manage the UI.
- ProfileInstaller (Utility)
AndroidX library that enables libraries to prepopulate ahead of time compilation traces to be read by ART.
- Room (Utility)
a persistence library that provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.

display large sets of data in your UI while minimizing memory usage.
- Android Activity Saved State (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.

Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.
- Viewpager (UI Component)
AndroidX library to display Views or Fragments in a swipeable format.
- AndroidX Widget ViewPager2 (UI Component)
replaces AndroidX ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.
- WorkManager (Utility)
an API that makes it easy to schedule deferrable, asynchronous tasks that must be run reliably .
- AppIntro (Development Aid)
an Android Library that helps making a cool intro for the app.
