Excellent
Mr Kunz is a master designer. I just got his HP 45 emulator which too is fabulous. Very thoughtfully designed, complete with crisp instructions, useful settings. It's a joy. I never had an HP 70 but looks like a simple, elegant product. Thanks!Cran43
Excellent Simulation
This app is both functional and beautiful. The calculator looks like the real thing and the animated buttons look like they actually move. The display is also an extremely accurate simulation of the actual HP-70 display. The paper currency background on the iPad is a very nice touch. The button click sound is cool and it can be turned off for silent operation. While this reviewer has not tested all the functions, the app has been tested thoroughly by the developer against an actual HP-70.
A very good simulation of a very powerful, classic, HP business calculator.Show lessWebunit1
Okay for a freebie
Not bad, considering how expensive some of the other virtual HPs are, but the 'buttons' are not very responsive and have to be tapped very firmly and deliberately. As such, it's too frustrating to use as a day-to-day calculator.Billablog
Good Job!
I had an HP-70 and used it a lot. From the few calculations that I made, this app seems to work just as it did.Maureen Long
Good simulation
I bought an original HP-55 years ago. I still have it, but I don't use it. I always wanted a financial calculator like the HP-70. This app is a faithful simulation.Restoring Tally
