free Amazon App of the Day - 8 June 2014 - Andro12C financial calculator
I know, I know, it's not an ebook - but this is an app that folks might run on their Android phones or tablets when not using them for e-reading (!) and I'm a huge fan of RPN calculators anyway.

This one is free today for Amazon US customers (normal price $5.70), and has pretty darn good reviews, although only a limited number (12). Basically it emulates the HP-12C calculator, which is sort of a classic among calculators.

Amazon really liked doing calculator apps as freebies, I think I have around 20 different ones now.

In addition to the stuff on the Amazon store, I have about 10 additional Android ones, including a TI-83 emulator.

On the iOS side, I have five third-party ones.

... And I have a TI SOLAR sitting on my desk from the 80's.

This is pretty nice though. How does copyright even work for calculators?

You can copyright a program's source code, but that applies only to that particular implementation. It's unlikely that the source is even remotely the same since they're running on different operating system and/or hardware. If you do a complete re-implication from scratch, that's perfectly legal. (Although it won't necessarily prevent you from getting sued. If a company sends a cease and desist, most people would just take the app down. Hiring a lawyer to defend yourself, even though the law is on your side, is really expensive.)

There's also a possibility of trademark issues, as you can get trademarks for "trade dress". That's basically the look and feel of an item. If HP had a trade dress trademark on the calculator they could put a stop to it if they wanted to. I doubt they care all that much though, I can't see this app hurting the market for real HP calculators.
