Great for longer operations, simple enough for everyday

The default iOS calculator is practical but the lack of history makes it less useful. I use it a lot when calculating my weekly budget. There probably better apps for that but this works great and I don't need any more complexity.

It could use a bit more features like being able to export calculations to notes and email. If it had that I would have given it 5 stars.

Works like it should

Great developer support. App works good on the iPad, which is missing a stock calculator.

Good App

The implementation of parentheses puts this app ahead of almost all other math apps. The only limitation- only 2 significant digits after the decimal point.
