In landscape mode, you have a robust calculator with a comprehensive set of scientific functions and tapes for keeping track of your work - everything in one single screen. Also, you can print your calculations with AirPrint technology or email them to friends or colleagues. Use of memory is dead simple too - always see what you have stored on the memory slots, and for using one value, just tap on it.

great calculator

I really like this calculator the best and I have two or three others on my iPad. I like the sounds, the bigger buttons, and the look of it on my screen. I highly recommend it. An idea for an upgrade, though, would be to allow it to keep adding the last number entered every time you hit the “plus” key just like the trusty old calculator on my desk.

I still really like MaxiCalc and I can’t really add anything else to my first review. The idea for the upgrade also is still valid. This app is well worth getting IMHO.

After purchasing a few calculators, in search of the perfect one, I found MaxiCalc. If I had found this earlier I wouldn't have bought/downloaded the others. My search has ended as this is the best calculator I've ever seen. There is nothing, here, not to like. I love the big buttons, the paper tape (which you can print or email, the sounds and all of the other features which give this the look and feel of those good old calculators that I really liked.

Couldn't be happier!

Without question no calculator in the App Store comes close. From the authentic sound to the ability to email the tape to a client, to the big buttons, to the ability to store multiple tapes for future comparison to the ability to AirPrint the tape immediately to a customer - I couldn't be happier! I have recommended it to multiple sales people as well as contractors to make their jobs more efficient. Get it, you won't be sorry!!
