User reviews

Freezes

Paid for the app and it freezes after using the calculator for less than a minute every time I open the app

Only a few equations

Not worth it

Response from developer

Thanks for your feedback. Our app actually has a wide range of statistics features. We'd be happy to answer any questions you have about the app.

Love the app.

Generally exceptional. One issue is that data entry is landscape but to clear the data you have to change to portrait and clear the buffers then click β€œdone” twice, to return to data entry mode again, surely this could be more streamlined?

Awesome

Yeah bring more features

Advanced

Very good
