There are better free calculators.

It’s not Too Late

It doesn’t work. It should, but it doesn’t. The number keys don’t work, and the calculator won’t rotate to reveal the more advanced settings half of the time.

Great! But...


Awesome app! I just got it and it's working great for me.I love the themes that you want choose from, but of you want the wooden one, you have to scroll through ALL of the themes that are there to get to it. Should be a button to view all of the themes to choose which one you want do you don't have to flip though all of the themes
Also, there should be more themes to choose from. I thought there was going to be a forest themed one, an ocean themes one, and a rainbow one! But there is only the school one, white one, classic one, wooden one, and pink ones! It is frustrating that there isn't more themes to choose from.
I love that there is a lot of commands if you turn your device into landscape mode. I love it so much, I got it for my iPad, and iPhone.I got it on my kids iPod touch, and she has been using it as a calculator very often.
Overall, I love it but think that it could be much better. I think that if you take my advice, the result would be a much better calculator app!

An Outstanding Upgrade


The audible key clicks that disappeared after the last update are back, the new visual themes choice is outstanding, and the recording tape is a potentially very useful additional feature. Nice job!
One quibble - in the history panel, when you click copy result, it never seems to copy the result, but rather the last element of the equation, but only if that is a number. If the last last element is an operator, it seems to do nothing, so when you paste, it pastes the last thing in the clipboard. It never seems to actually copy the result.

Not sure why some are upset with the new visuals since all the old standards are there (although flattened).
