“Recent user voice shows a mixed sentiment. Users appreciate feature richness and utility for education, but report ui/ux regression and in-app purchase/pro access issues.”
What Users Love
This calculator has every function pretty much anyone could ever need
Covers many scientific functions and calculations.
This helped take off so much homework!
I have been using this in school, and I will continue to use this in school.
Pain Points
the new version does not have a running total. the app was good the way it was
They changed the UI on they latest release. It’s now awkward and hard to use.
I paid for the upgrade but it doesn’t work…still says I don’t have Pro Access.
services cost money, but it shouldn’t be on potential customers to find this out after getting the paid app.

How much does it cost?
Model: freemium
The app uses a 'freemium' model where core scientific calculator features are free (on Android) or paid (on iOS), but advanced AI-assisted tools are gated behind IAP to monetize power users.
