Works well on iPadOS 13.1.2 – HP 15C Calculator Review

With so many recent negative reviews related to iOS 13, I’ve never tried on 13 until this holiday season (December 2019). HP did not update the version number nor the date but just for the record, this app actually works well on iPhone iOS 13 and iPad iPadOS 13.1.2 Excellent job HP calc, as usual. Very happy holidays! p.s. This app runs blazing fast if you happen to have an original HP-15C to compare with :-)
