Calculator HD Pro

iPad doesn't have a bundled calculator app, so this is perfect.

Love this app. It is simple to use, clear graphics, great big calculator sound and you can see what you have entered scrolling across the top.

This app has all the functions I want but takes bout 10+sec to start on my iPhone 4S. Prob not gonna use this Calc app until they improve on the start up speed.

New landscape mode is a big improvement. Developer very responsive to suggestions for improvement.

After years of use, this is still my go-to calculator app. Not only are the layouts customizable and easy to read, and the entry easy to modify, but the results can be notated and saved for later recall. Perfect

Simple yet powerful. I use it in my Real Estate business everyday.

Best calculator I have ever used.

Unless you’re an astrophysicist this calculator has everything you need for calculating everything needed! Yea! That’s a bit of a hyperbolic description, but it really does have everything you need: trig, algebra, and lots more, and the more mundane addition, subtraction, multiplication, and division. I’m an amateur astronomer and it can do all I need!!!

This is a wonderful calculator. The interface is uncluttered and it's easy to use.

Me encanta el diseño, la variedad de servicios. Es muy útil para mí. Gracias. Muy atractiva
