What PCalc does

A scientific calculator for iPhone and iPad, with an accompanying Apple Watch app.

Documented features

The official listing documents the capabilities below. Compare the functions you need with the available platform and paid-feature information before installing. These are the developer’s descriptions, not independent performance or security test results.

“PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator.”
“Includes an Apple Watch app, so you can calculate on your wrist!”

Installing and opening PCalc

Open the Apple App Store link, confirm the product and seller (TLA Systems Ltd.), and use Get or the displayed purchase button. The recorded minimum iOS version is 15.0. Check the compatibility section on your device before purchasing: an iPad or Mac screenshot does not establish that every feature works on an iPhone.

For the first run, follow the app’s onboarding and then use the workflow described below. Keep a copy of the original file or record when trying import, conversion or editing functions. If an Android button is present, it links to a Google Play entry found on the developer’s website and checked against the product name; platform editions may differ.

Using the documented workflow

Start with the operation that matches your task. The following actions are documented in the official listing; they are separate usage options, not a sequence that every user must complete. For controls not named here, consult http://www.pcalc.com/iphone/ rather than assuming a particular button or menu exists.

“It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations.”

Platforms, version and interface languages

Verified store editions: iOS. The captured version is 3.14.4, with an update date of 2026-03-12. Version numbers and release timing can differ between stores. Check device compatibility in the current store before downloading. An edition for another operating system must be verified separately; a similar name alone is not enough.

The official store lists 1 interface languages. The supported-language tags on this page come from that product metadata; they are separate from the eight languages available for this guide. Check the current store if a particular language is essential to your workflow.

Price and paid features

At collection, the US App Store initial download price was $9.99. This is the initial store price, not a guarantee that all features are included. The initial download is a purchase. Optional upgrades or connected services, if offered, may have separate charges.

Permissions, privacy and practical limits

Before allowing access to photos, files, the microphone, contacts, location or notifications, check whether that access is needed for the function you intend to use. The App Store privacy section describes the developer’s disclosures; the presence of an App Store listing is not a guarantee that information stays on the device. Review the developer’s privacy policy before importing sensitive material.

For account or synchronization problems, use the developer’s support channel. Back up important content before signing out or reinstalling; deleting the app is not a substitute for canceling an App Store subscription.
