Good app

I like this calc. The only thing I think it is missing options to change the lay out from simple to complex. Other then that it is easy to use.

Nice calc app with no ads but... small bug I think?

It's calculator works great and the history is nice. However I am having a hard time using it because of the way the equal button works. I think there may be a bug when pressing the equal button after a computation. For instance when I press 4+4 then = I get 8. Great, but then on my next computation I press 4+ and 4 is added to my previous computation and I get 12. Really what I wanted to do is 4+x=. I don't want it to add to the previous computation unless I didn't press =. Maybe it is just me but all the calculators that I use automatically start a new computation after the = sign is pushed, unless + is pushed before the number.

For example 4+4=8 then I press +4=12. But if I do 4+4=8 then I press 4+ my other calculators are waiting for the next variable whereas this app has already added 4 to the last number computed. Very annoying!

Please update! If this bug is fixed I will give five stars!

It works!

It works quite well. And the sound effects can be annoying so add integration with the settings app so we can mute/change the volume.
