One always expect more out of any app, and this one is no exception. But for the price and ease of use, specially ease of use, this is a pretty incredible app.
Very Good Calculator.. Highly Recommended..
Expected more There is no denying that this app is capable of a lot, but for the price, it is not worth what you get. I can't remember exactly what limitations the free version presented, but I don't recall any increase in functionality, besides the water mark. I expected a lot more, and if it were more intuitive, i might actually use it a lot more. But for less than half the price, there are better apps out there. The free version is great. I'd give it five stars. But I'm just not exactly sure what it is i paid for.
