Calzy 3

Brilliantly user friendly. A Joy to use.
Looking for more innovative apps from this gentleman.

Useless as a scientific calculator!

The designer has acknowledged that there is still no way to enter negative indices making this all but useless for scientists. Emails have remained unanswered and a refund request was ignored. Such a shame for an otherwise well designed (and much hyped) application!

Developer Response ,

We fixed this issue in the latest version. Sorry for the inconvenience.

Worth the cost

Glad I spent the money on this. A calculator on phone that I actually use. You can type in your calculations much as you would say them. Don't find myself worrying about syntax. I particularly like that I can see the history of what I have calculated as I go along.
