Love the interface, which is clear, classic calculator graphic and layout. It also gives positive feedback when you tap a key. All this makes it fast and easy to use - what more could you want? The trig functions all give accurate calculations (unlike another calculator app I had downloaded). it is also good value to remove the ads. Nice app!

Very happy user of the app. This app arguably the best scientific calculator app on the store. Developer is very responsive too. I requested a minor UI change and it was implemented within one day. I would highly recommend this app.
Enforce integer computation in Base N mode. Add option for backward compatibility
