About
ExtCalc is an innovative scientific calculator that makes operating computations easy. It shows your whole formula in a colorised text view. You can have different calculation sheets for different formulas or you just use one sheet for all your formulas. Deletion and memorizing results are integrated as well. Last, but not least, it includes a customizable constants pool and a VAT calculator. All nifty features in a short list: * Individual calculation sheets, with the possibility to print them * Color highlighting * Memorizing results, e.g. via the ANS button and through the calculation sheets, get old values by tapping on them in the sheet * Many functions, even in portrait mode * Grouping (brackets) * Error proof, you can't input formulas that would lead to errors * Constants pool, easily customizable * iCloud support for synchronization between devices * VAT calculator * Apple Watch app * Cloud synchronisation to stay up-to-date on all devices * AR scene * Print calculation sheets * Dark Mode * Strong focus on accessibility Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://develicious-studios.de/privacy.html
What's New
Version 5.0 • Sep 19, 2025
We changed a lot: the design has changed drastically, leveraging the new Liquid Glass. It provides a cleaner navigation within the app and a colorised calculation view. Additionally, we enhanced accessibility a lot, so we hope that more people can easily use this app. The Watch app can now operate on its own, it has a list of all sheets that you edited on e.g. your iPhone. It uses the last number and any new result will overwrite this result. We changed to a subscription model for this version, as it is needed to further support the development of the app. Though, we provide a free trial period at the beginning, so you can see if you like this app (and we hope, you do ;-) ).
