About this app
With microMathematics Plus, you can not only perform mathematical calculations in naturally readable form, but can also create and manage your own collection of interactive formulas!
The microMathematics Plus is a revolutionary new kind of mobile calculator. It is the world’s first scientific graphing calculator and function plotter on Android oriented around a worksheet. It allows live editing of mathematical identities combined with highly accurate computations.
The app is 100% open source. Please feel free to download, explore, fork or contribute to it on https://github.com/mkulesh/microMathematics
Not only students, but also everybody who likes mathematics or needs more than just a basic calculator will benefit from this amazing technique of mathematical calculations and plotting.
Benefits and features:
* Maximum privacy: No ads, no trackers, no telemetry, no special permissions * The modern Material design supports different color themes and works on smartphones and/or tablets in portrait and landscape mode * Verification, validation, documentation and re-use of mathematical calculations * Works on smartphone or tablet in portrait and landscape mode * Supports all commonly used mathematical operations * Mathematical expressions are written in an intuitive and naturally readable form * Supports SI and non-SI units (including units of information) * Powerful mathematical touch-screen editor with undo function makes editing easier * You can do multiple calculations and subsequently correct or change all used formulas * It is possible to store intermediate results into 1D, 2D, or 3D array that can improve calculation performance * Mathematical expressions are collected in a document, that includes not only formulas and plots, but also additional text and images (SVG format is also supported) * You can store your document on SD card and export it into LaTeX format or an image (SD writing permission is needed) * SD card on Android 6+ is also supported * The app contains detailed "How to use" page and several examples * Supports data import from ASCII files * Supports units of measurements, arrays, complex numbers, functions of many arguments, plots for several functions, contour and 3D plots, summation and product operations, derivative and definite integrals, if-function and logical operators, Fourier transform, root finding.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
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.mkulesh.micromath.plus 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, 2.23.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall microMathematics Plus 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 microMathematics Plus, and a listing is removed when the evidence for it stops holding up.
