Great app

This is a wonderful calculator. I use it for work almost every day and it is perfect. I mostly use the basic calculator, but the currency calculator is also very useful as is the metric converter. I also find the tape feature to be extremely handy. Some users might also find the other modes such as scientific and graphing to be valuable. Finally, it is worth the money to buy the app in order to get rid of the adds.

Best Calc app

Love this app. I bought the app to get rid of the ads. The tape is great, and the fact that you can see all transactions and touch one to have it copied to the calc screen is very useful. I only use the basic calculator, but the others seem to be very valuable to esoteric users.


Calc pro

Great app. Purchased for my I phone 3G a few years ago. Loved it then on phone. The app meets all my needs. I really like the HD version for IPad the tape portion of it is very useful to see what you have entered into box
