FAQ

Is Calculator - Keyboard Support worth paying for?

Does Calculator - Keyboard Support work on all iOS versions?
The app has not been updated since July 2023. While it may function on current iOS versions, the lack of recent maintenance means it may not be optimized for the latest system-level changes.
What is the main difference between this and the native iOS calculator?
The native iOS calculator requires switching apps. Calculator - Keyboard Support differentiates itself by allowing you to perform calculations directly within the system keyboard interface, which is designed to reduce task-switching.
