Can’t have multiple calls open
Dhjdhj

I had the 11, 15 and 16. Opened one today and was told it was being “sunset” and I should get this one instead. Once I opened my old ones, the new app worked fine with no ads. It it has one huge disadvantage. I use to keep the 16 and the 11 open at the same time. Now I have to switch modes. That is NOT an improvement.


Great app. Worth paying for
Labyy

I originally downloaded the free app. I upgraded to the Palladium version for $5 and it didn’t work. It started working and it’s fantastic I think I did something wrong. It’s worth paying for the ad free version and for it to display vertically as well.


Basic math?
Astrostar1

Basic math, divide and multiply, do not work. Is that intended with the free version?


Looks like garbage on iPhone X
Cybersnyder

Everything is fine on older phones, but the layout is garbage on the larger screen. Avoid.


Want an 11c like I had before!!
LWB2002

Shouldn’t have deleted the old one before finding out this was a financial calculator - not an 11c. Doesn’t seem to have a way to turn on key clicks either. Should have kept ignoring the pop up window telling me to upgrade! No ads on that one either.


Great - with one exception

I love this app- looks and functions just like the real thing. However, I have one problem with the display. Maybe it’s a setting that I can change, but I can’t figure it out. This is not the classic “the comma and decimal are switched” complaint, because I know that is fixable. Rather, my problem is with comma placement. After the first comma separator (between the hundreds and thousands), which is in the right place. It starts putting commas every 2 spaces instead of 3. So 7 million displays as “70,00,000.00”. 700 million displays as “70,00,00,000.00”. So far it doesn’t appear to affect calculations, but it’s really annoying


It’s got distracting advertising
Dhjdhj

I had the 11, 15 and 16. Opened one today and was told it was being “sunset” and I should get this one instead. Downloaded it and it displays incredibly distracting ads on the top right (which somehow conveniently don’t appear in the screenshots)


Very disappointed, would like a refund
Steelheadhunter

Had the 11c and liked it. Was offered this instead of a refund. Don’t want a 12c, that’s why I purchased the 11c. Recommend spending with someone who supports their product.


Good but ...
softwarehobbit

As the owner of a real HP 11C, it’s nice. But a couple of nits: The program does not accept input from a Bluetooth Keyboard. I’m not looking for magic here, but it should accept numerics, Period, Enter, Delete, up/down (roll the stack), +-x/. Maybe also C (CHS) and E (EEX), and CMD-Delete (clear stack) Why if one is has paid for the Premium Scientific calc one does not have access to the basic version?


Odd behavior
Huskerfan69

Why is your app the only one that consistently has a window popping up asking me to input my Apple ID password? No other app I have does that. Coincidence or not. You be the judge.
