AlexCalc

AlexCalc is a calculator application developed by Alex Barry, packaged as a single Android APK of version 1.0 weighing in at 13.56 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 13.56 MB, so it installs quickly even on modest connections.
3. This build is signed by "Alex Barry" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

• nicely formatted (LaTeX) equation display. This avoids the need to count brackets to make sure the equation was entered correctly. Also includes LaTeX code generation.


• complex number support, in rectangular or polar form (e.g. `3 + 4i` or `1 angle 90`)


• variable storage (e.g. `123 -> x` then `3*x^2 - 4*x + 5 -> y`)


• units in equations, and conversion (e.g. `1 inch * 3 ft to cm^2` or `sqrt(60 acre) - 100 ft`)


• can enter input by button presses, typing, or copy/pasting. Button presses are all converted to plaintext input for easy copy/pasting.


• equation display is simplified upon pressing enter. This means that when entering an equation, it is usually possible to look only at the LaTeX display and not the plaintext input: but when pressing enter, it will look nice. Redundant brackets are removed, including those that are needed for plaintext input (e.g. `(a + b)/(c + d)` can become "a + b" on the numerator and "c + d" on the denominator without brackets).


• light/dark themes


• previous input history can be accessed and edited by pressing "up" or "down" buttons.


• previous inputs/vars/recently used units preserved when the app is closed


• standard scientific calculator features, such as:




• trigonometric functions: sin, cos, tan, arcsin, arccos, arctan


• base 10 and natural logarithmic functions: log (base 10), ln (base e)


• `e`, `pi` constants, and square root function


• scientific notation input (e.g. `1.23E6` is 1.23 times 10^6)

Is AlexCalc free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does AlexCalc require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is AlexCalc safe to install?
We link to the exact APK published by Alex Barry. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update AlexCalc?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded net.alexbarry.calc_android.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «AlexCalc» by Alex Barry and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
