HP 12C Platinum Calculator

It doesn’t work… did tested with example at pag.50 of the manual when you request “n” it crashes…

It doesn’t work and crash on iPhone Pro iOS 14.3. Fix or Money back?

Please, update to iOS 11! Good app

I bought it, 'cause I like it real, and fake's not my thing. Even with a high pricetag, it's HP that just invented it and I thought the deserved its premium. Well, I's wrong. Two (most) annoying features that the user can address, that have been repeatedly asked by the whole user community, are not included and have not been included in updates (which do not seem to have been issued, by the way). For one, you can't use most of its functions unless you turn it horizontally. It doesn't seem much of a thing, but when you have it lying onto a surface like a desktop, and you already have to swap between apps (a catalogue, a mail message, a web page), adding the 90 degrees rotation too makes for a totally different dance, and quite disappointing. And the next boooo goes for key-click sounds: cheap, like in the 8-bit lo-fi world, but loud, too loud for any civilized office or venue... and you can't turn it off without affecting the phone main volume? You joking? Well, copies, imitations, renderings of the real thing done by third parties address all these issues, do a lot more and cost barely a third, forgetting for a minute that with their price paid once, the user has a right to upgrades that, in case of the "original" one in iOS version HP never seems to have released. I feel I've been ripped off. I'll use the non-HP version and support its maker, which is way more honest and markets a more genuine tool at a fair price. Now, will this review ever stick to the product page on the appstore? 'Cause I've seen none, when I bought this, but thought HP did not need any. I was wrong. Probably all reviews do play a similar tune, and that's why they're not appearing. Shame.

Aplicativo com BUG, quando aperta CLX ele fecha a aplicação. Não atualizam…. Me sinto lesado por perder meu dinheiro com isso.

Não funciona nada direito no iPhone

Paguei e não abre a HP. Não funciona. Furada.

Como pode não funcionar direto ainda…..

Gostaria de receber o valor novamente. A calculadora é bugada.

Tenho um iPhone 13, acabei de comprar, abre somente metade da imagem da calculadora,
