Works well but needs refining. Free ads poorly executed

Mr Edward

Generally works well, responds reliably and quickly to key presses (unlike some others in the app site where key lag sometimes causes missed entries).
The feature list is reasonably comprehensive.
It would be nice to have a horizontal layout option with the paper tape visible, especially for the new larger iPhone screen sizes. Swapping back and forth between screens is awkward when trying to refer to recent calculations.
Also useful would be the option to edit or reuse longer equations from the tape.
Minus one of the stars because ads in the free version seem to freeze and do not allow a means of returning to the calculator.

Great free scientific calculator

Mr DMan

One of the few scientific calculators that has a log and antilog function which is easy to find by using a 2nd Function button like you would find on a real scientific calculator. That is only the beginning with in-app purchases of all sorts of useful calculators. This is a winner for me.

Couldn't do without it


A really well designed and very comprehensive calculator especially if you get the bundle with all the functions. I use it a lot and like the conversions functions most. Only critique is that it takes a bit too long to load up from cold (nearly 3 seconds).
