★★☆☆☆Delay in entering
I’ve had this app for many years, and has been a 5 star app for most of them. Somewhat recently there has been a delay in entering key strokes making it annoying to use. The HD (iPad) version doesn’t seem to suffer the same delay. Unfortunately, the iPhone is where I use it the most.
★★★★★Very nicely done!
Very nicely done HP-45 emulator, plus the "extra" features are a nice bonus. Beautifully executed, including the timer mode.

I recently spent 14.99 for ClassicHPCalc for it's HP 35 option. I was so disappointed that it is not even close to this Apps realism. I really hope that this developer does an HP 35 version of this at this quality level. I'm proof that
