Good app. Needs tweaking.
The app is good though a little bit pricey when considering that there are far more powerful calculator apps that are less expensive. (HP is preying on the sentimental engineer who misses their HP15C)
The following improvements will be appreciated:
1) Expand options behind the "Menu" icon to include the following:
a) Link to App developer support. (How hard would that be?)
b) A switch to turn off key press sound feedback so that the user doesn't annoy their co-workers or people trying to study in a library.
c) Turn off the blinking after providing the calculated answer given after using a programmed set of functions. (The blinking answer keeps blinking at you and it annoys the blinking blinking out of the user)
Update needed- and deserved, at this price
Good replica - but not yet upgraded for iPhone6 - nor even ios9.
Main screen just a little too small on my phone, with borders in landscape- if it filled the whole screen it would be much more usable.
Manual uses old style buttons, not iOS 9.
I like it- but was not worth the $ I paid. Next time I'll try a 3rd party copy.
Back up to date
A few improvements over the older version, not least of which is the quieter key click sounds. I was dreading the thought of losing the 15c, I can upgrade to iOS 11, now.
Up to six family members will be able to use this app with Family Sharing enabled.
