Customer Reviews

Please update the app to a 64-bit architecture!

I use the HP12c Platinum calculator app almost everyday for years now. I sincerely hope HP will update it to a 64-bit architecture so that we, loyal and satisfied customers, will be able to continue enjoying this app in future versions of iOS! Please update it, please!

HP needs to update to be able to function w current iOS

WARNING TO ALL, Do not download this App. I was excited to downloaded the HP 12c Platinum App. My previous 12c clone was acting up with the latest iOS. Decided to get the real thing from HP. Once I downloaded and tried to use it, message stated, HP needs to update the App to work with latest iOS. So, now what, $18 down the drain.

For being the industry standard, it fell flat

The app is unstable and continually crashes. I constantly get pop ups in iOS that the developer needs to update the app in order to support the new system. For a $15 app and a multi billion dollar company you would think it comes with our better support...
