WP 34s

All fine except battery usage.

This is an emulation of one of Hewlett Packard's most powerful machines - now on steroids, taking advantage of modern computing. Beyond being fully programmable, it has a bewildering amount of functionality, so it's great to find vitally important user manuals are available. It works just like it's cousin here in the App Store: the WP31-S, except this has even more. The only downside: it takes a while to become familiar with the keypad.

I give this 5 stars. In the little specialist world of HP calculators there has been a BIG project amongst the more tech savvy users to create for themselves the perfect HP calc, that from HP never quite was. This is basically that project, which reached maturity, and put onto an IOS device. So it deserves 5 stars. Thank you. It's not the prettyest HP calc on an IOS device, but that's to miss the point of this.

I have a real WP34s which is a good calculator but when I don't have it to hand this is a great second best. Wonderful emulator. The only problem I've found is that the 'Key Click' setting doesn't persist.

It would be great to round off this great looking and working WP 34s with a few features from similar emulated calculators (like Free42 and HP-12C): - Printing simulation into a separate screen and saving to image and “log” files - Shift Highlight: green and orange are somewhat similar (for some of us), so when a shift is activated, highlight the affected functions with higher intensity (brighter) color. Other potential improvements: - annunciators could be a little bigger - multi-line stack, registers or program views

I have the HP30B and a converted WP34S. The only issues with this update is that all the pick lists are darkened and are not readable, for example, key in h and X.FCN and you won’t be able to read the choices.

Great HP clone calculator. No issues at all and on top of that the great ol' classic look.

Excellent engineering calculator, however there is a terrible battery drain and device heating issue when the app is running. Otherwise, this would easily be a five-star app.

Excellent, powerful RPN calculator.

I downloaded both this one and the companion wp-31s, both are extremely well done. Just a FYI, the "show" command works differently in the two apps. I assume that the wp-31s behavior is correct and this app has a problem. Great apps other than that.
