12C Platinum

This is no longer a 12c. Stuck in algebraic mode. Where is RPN? Lost that realistic look. Ugh. Go back to the old version!!!!!

Why I can't re-download in my iPad, since I've already purchased the app???

I updated this app as it finally supports iPhone 5, but then I found the currency exchange function is not working at all. The exchange rate is always 1.0 whatever currency I choose to convert. <br/><br/>Update: the support person said they will update the app and solve couple issues. I told them about the currency conversion issue. After latest update. This is not resolved at all. Terrible.

Just like the real thing!

As Pee Wee Herman once said,&quot;Everybody has a big but&quot;<br/>the upgrade is very nice and easily switches from algebraic to RPN, although I had to figure out how.<br/>my big but is that after the upgrade my icon constantly says &quot;waiting&quot; i can only access the app by &quot;open&quot; command from the app update page

Stinks now that it's switched to a non HP format. HATE it now!!!

V5.5.1 is awesome... Has all the capability you would expect and more.

Thank you so much for your latest version which has updated this invaluable app to me to be iOS 11 ready. This was a most pleasant surprise as I've been actively looking for an alternative. Thank you also for making this a free upgrade to your established clients.
