I would give it a 5 except for two things
First and most serious -- -4 squared is not -16, it should be +16 -- this is not consistent with the way the 12c works.
Highly annoying is the loud, unregulatable key click -- it does not respond to the app volume. It makes it unusable in meetings, sadly to say. Availability when I do not carry one of my 12c calcualtors was a big reason why I purchased this app.
Less annoying but an irritant none the less is the inability to lock it in landscape mode. It just means a longer wait since it always starts in portrait mode (why I cannot imagine) and then has to figure out that it needs to change.
Since HP has not updated this since 2009 and we do not know if they are even reading these coments, I have little hope that any of these items will be fixed.
Embarrassing! Calculation errors!?
Hewlett Packard has a loyal following and a reputation for highest quality - and for correcting problems when they arise. (Early HP scientific calculators actually were recalled and replaced when a tiny bug was discovered.) But a business calculator that makes elementary-school math errors (e.g., in squaring a negative number) is unforgiveable!
The calculator on which this app is based goes back to 1981, and among financial wizards both old and young, it is still the gold (well, platinum) standard! This iPhone version appears to have been introduced in 2009, which should have allowed HP plenty of time to get it working credibly under OS 3.1 or later.
HP 12c. Very satisfied
I just downloaded the app and it works fine. I was able to lower the volume on the keys. It flipped to horizontal quickly. It has nice new features like Undo if you clear a number by mistake. It has back space so you can correct a number. It also has a built in quick start manual for new users or if you forget how to input something. It's really great to have an HP in your pocket. Very satisfied.
