Perfect Replacement for iOS Calculator

As advertised, this calculator has a clean look and elegant feel. The layout is nicely proportioned between the scrolling output and the (easy to touch one-handed) buttons. To achieve this the keyboard has been stripped of the functions that people don't use, such as "random" and %. Also no need for the memory buttons since you can long press an answer to copy it to the input field. I thought it a nice touch when I saw that the clear button turns into backspace button when you type. The input field allows you to write out a full expression like most scientific/graphing calculators, so you can remember where you are in a calculation. I was glad to see that the "alt" menu had the inverse trig functions, which is something that is missing in the iOS calculator app and that I use quite often. Apple has really dropped the ball on their calculator and these folks picked that ball up. I haven't found any errors in calculations, which I thought could be the case with the carrot, but no. I don't see a need to ask for any other features as that would ruin the concept of this app... just what you actually need!

As of writing the review the in-app purchase allows you to calculate in radians, and therefore the default is in degrees.

Thank you for the kind words and sorry for the (very) late reply! Hope you're still satisfied with the app :)

Best Scientific Calculator! (1 Year Review)

This is my favorite scientific calculator in the App Store. For me, it’s the best combination of functionality, visual design, and app support.

It looks great and works really well. The paid features such as smart parenthesis and quick copy/paste are definitely worth it if you’re working on lines of operations that require accuracy (college math, physics, engineering, and chemistry)

Finally, the developer Andreas, was super approachable and quickly resolved an issue when iOS 14 launched.

Thank you so much for the kind words! Your support means a lot and of course it's my pleasure to help resolve any issues or bugs.✌️

Could use more scientific options such as complex math

I have found this to be a good calculator for basic arithmetic. It is free, so one can’t complain, but I would think that a scientific calculator would think complex arithmetic would be a useful add for scientific applications. Also, I haven’t seen an option like complex exponential. Thanks for asking, and I hope you view this as constructive criticism.
