HP Prime iPad/iPhone question

[DrDarius]

I would like to learn about your opinion on iPad/iPhone app which is available for $25 from HP.
The reviews in the App Store are definitely negative: the app keeps crashing to the level of not being usable. The app has low rating. The past comments I found in this forum are also not favorable.

I would like to learn what’s going on with the app before I make a purchase. $25 is not a huge amount of money, but I’d rather not throw it down the toilet anyway. (Call me frugal.)

I am mostly counting on the honest opinion of the insiders (Tim? Cyrille?), but any app user’s opinion would be appreciated.
