About this app
Excellent scientific calculator with step-by-step solutions, symbolic algebra, graphing, equations, integrals and derivatives.
The calculator has globally more than 50 million downloads and 250 000 five-star ratings.
You can write expressions in a natural way and watch your calculations. The result is displayed as a number, simplified expression etc.
An expression can also be entered from a photo. Take a picture of a handwritten or printed expression, and the calculator recognizes it and inserts it into the display, ready to be edited or evaluated.
A step-by-step solution shows how an expression is solved, one step at a time, from the entered expression to the final result. Every step is explained, so you can see not only the result, but also the way to it.…

Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
What we measured

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
