NerdCalci is a powerful calculator designed for nerds and power users who need more than basic arithmetic.

Features:

Offline - Works without internet
Variable support - Define variables and reuse them in calculations
Percentage calculations - Natural syntax like "20% of 50000" or "15% off 1000"
Unit conversions - Natural syntax like "10 m in feet" or "100 kmph to mph"
Custom functions - Define your own functions with multi-statement support and scope isolation
Dynamic variables - Quickly compute block sums (total) and averages (avg)
Syntax highlighting - Color-coded numbers, variables, operators, and comments
Smart error diagnostics - See human-friendly explanation of math or syntax errors
Auto-completion - Smart suggestions for variable names
Comments - Document your calculations with # comments
Multiple files - Organize calculations in separate files with auto-save
Pin files - Keep frequently used files at the top
Search - Search your files easily
Duplicate files - Create a copy of a file with a new name
Undo/Redo - Up to 30 steps per file
Backups - Automatically or manually backup your files to app storage or a custom folder
Restore from backups - Restore your files from backups
Copy with results - Copy calculations with their results
Export - Share your calculations as a PNG image or a multi-page PDF
Dark/light theme - System, dark, or light mode support
Line numbers - Easy reference and navigation

Perfect for:

Quick calculations with reusable values
Budget planning and financial calculations
Unit conversions and formulas
Educational purposes and learning
Any scenario where you need to document and reuse calculation values

NerdCalci combines the simplicity of a calculator with the power of a text editor. As a capable alternative to text-based calculators like Numi, Calca, and Soulver, it is ideal for developers, students, accountants, and anyone who frequently works with numbers.

WhatsNew:

- Added `factorial()` and `fact()` built-in functions (Issue #69).
- Fixed an issue where the user-defined result precision was ignored during PDF and image exports (Issue #73).
- Improved `total` and `average` variables to preserve units and handle dimensional safety (Issue #74).
- Fixed precision loss bugs for very large numbers (Issue #80).
- Fixed mixed temperature addition and subtraction so values normalize consistently before arithmetic (Issue #83).

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).

a framework to define UIs programmatically with composable functions that describe its shape and data dependencies.
Concurrent (Utility)
AndroidX library to help move tasks off the main thread with coroutines and take advantage of ListenableFuture.
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.

AndroidX library to use animation interpolators on older platforms.
Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
Navigation (Utility)
a framework for navigating between 'destinations' within an Android application that provides a consistent API whether destinations are implemented as Fragments, Activities, or other components.

a set of core libraries that includes new collection types (such as multimap and multiset), immutable collections, a graph library, functional types, an in-memory cache, and APIs/utilities for concurrency, I/O, hashing, primitives, reflection, string processing, and much more.
