HP Prime Graphing Calculator for iOS.
HP,

I purchased the HP Prime Graphing Calculator for iOS. Questions:

- Is it possible to update the HP Prime Graphing Calculator for iOS to '2016.04.14 r10077'? If so, how? If not, is it necessary for HP to update our software via iTunes / App Store. Is it coming?

- I have noticed the keyboard (graphics) are crystal clear, but the virtual display seems low resolution. I suppose what we are seeing is exactly what is written for the actual HP Prime 320x240 frame buffer? What would it take to increase the output for our retina iPhones / iPad / iPod? Am I asking too much? Has it already been discussed? Is it coming?



Thank you,
P Gyore

So far I have not seen any upgrades to the iOS version of the Prime. The latest version is 9069 (11/2/2015).

Yes, that is necessary. It isn't an "emulator" that runs the binary from the calculator, but is an actual platform specific build for each location it runs.

Yes, that is correct. It is the same size and resolution.

There are a lot of changes internally in the code to support that type of thing. Think about something simple like drawing a line. When you are on a high resolution screen, should that be a 1 pixel thick line? Or should it be thicker so you can see it easier?


As for any future looking statements regarding when or if, I cannot make those at all. The resolution independence issue is a known problem and we'd definitely like to address it at some point.

Tim,

Thank you for your response. I look forward to updates and am already impressed with the Prime. I will most likely buy one now that I have had a chance to use the software version.

Best regards,
P Gyore
