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.

Won’t delete my history

Annoying bug where no matter what I do, my last equation stays up. Really annoying for widgets
