This is the calculator app I have been needing!

10/10. Very powerful and user friendly. Apple should buy this and make it the default calculator!

The Best Calculator App

This calculator is so simple to use!
The best thing, is that I can see everything Iโ€™m doing, with Apples calculator I canโ€™t do that. This app also has a very clean design and I have used it for 2+ years and have not had any problems with it.

Keep up the great work!

Love the developer, wish I could hug them

This is legit the best calc app for basic operations, better than the default apple calculator. I saw the developerโ€™s post on Reddit a while back asking to check the app out. I honestly thought it was gonna be crap, but I was completely wrong.

To the developer, keep working on this calc project and adding more operations to the point where this app has as many operations as the default apple calc.

better than calculator!

amazing app!

I use it daily for work.

Easier to open this up the. Grab my calculator for my engineering work. Requesting a copy paste option. Would be helpful to be able to snag large numbers and paste them.

Just to clarify, I mean from outside the app. There is currently no ability to copy from outside the app and paste the number in.
