Excellent app to access all flavors of the classic HP Voyager models of calculators. And the premium models switch button is a quite nice convenience feature. Last but not least, the exact same Voyager calculator apps are available on the desktop browser from the developer's website.

Is there only an add version now? I paid for the pro version before. Support showed me the errors of my ways. No ads now, back to 5 stars.

Love this calculator. After learning RPN, I can never go back to an equals sign. Had some trouble transferring my prior purchase to the newer app, but the developer was quick to respond and got it solved. Thanks!

Had a little problem regarding the Premium version of the financial calculator but after a feedback from the support its working fine. Thank you!

If you are on a much older version you like, do not upgrade. I inadvertently updated this once outstanding, polished app to the advertising layden monstrosity it has become. If taking values from another app, you are presented with an unclosable ad for each number entered. I like that developers can monetize their work product but seriously, when you have to be subjected to multiple full screen ads and play find the tiny close hot spot just to do a single calculation it has gone too far.

New update has ads, although I Previously paid for ad free version. Tried changing the"flavor" back to premium but wants me to pay for it again. This is NOT what I originally purchased! Please fix, or refund the original purchase.

Careful with this seller. He removed the previous premium version, which I bought and re-added it to Google Play under a different name (Same app I believe) to get people to buy it again. Looks like he said it wasn't his fault, but I did not receive a refund to buy it again. I bought a different version.
