Touch Fin financial calculator

This calculator is a perfect mirror of my old 12C but now they want me to upgrade to some kind of combination of calculators? I'm afraid to do that. It's perfect and an upgrade can only be a bad thing? Please tell me it's going to be okay because I'm tired of getting the upgrade message every time I open it.

Superb HP-12c emulator -- has outlasted my calculator. Excellent privacy policy.

This is great. But can we have an option to lock the screen in landscape mode? (Edit, got your reply, that works, thank you!)

I previously purchased this app and had to pay for it again to get rid of the ads on the free version which I have already done before. Had to keep my payment in place to want others with my review. Although it works fine for a financial calculator, I've paid for the same app twice. Choose the competition and only pay once.

I needed a replacement for my Andro12c when I switched phones and I could no longer find it in "my apps." So I purchased this version only to find it is made by the same Dev as Andro12c! This is the best and simplest 12c emulator but I feel a little duped into paying twice for the same thing. Thanks Elvis. Otherwise would be 5 stars.

Since I don't want to take my HP 12C on business trips (it's an older one, before production moved to China), I needed an app for my smartphone. This one is the real deal; apart from the lacking keyboard feel, it is just like my actual 12C. Or actually it's better, since you can save state, and copy/paste. Portrait mode is useless for me; all of the keys are in the wrong place then ;-)

Simply outstanding. Beautiful and blindingly fast. If only it felt like touching the real buttons of the actual HP 12C.

This calculator has all the function of the physical calculator. I love using it. However it does not transfer to new phones.

Originally purchased Andro12c and loved it for old phone. Now with new phone I am forced to repurchase app again! This is the last time for this as I feel ripped off.

Had the previous version (for a number of years) which miraculously disappeared from my device and the store but it was so good I'm not going to argue about paying again. When I have had issues in past I wrote to developer and he responded immediately with a fix so I'll treat the repayment as an annoying blip.

I've used this app for years and love it. I've downloaded many different hp12c emulators and this one is by far the cleanest, most visually pleasing and easiest to use. HOWEVER about a year ago there started to be a noticeable and annoying delay between the moment I touch a key and the moment the haptic feedback responds. I thought it was because my phone was getting old and slow but I bought a brand new phone and i still have the same problem. PLEASE FIX. It can't just be me. I am using a Moto Z Play now; before I used a Google Nexus 5. I use this app several times a day every day and the haptic delay is very aggravating. But it's still the best HP 12C for Android by far.

Love this app. Beautiful emulation of the HP 12c. Really well done. I use it constantly.

It would be great if you include the possibility to use this app as a Widget. I use this app all the time.
