Are these programs put out by TI for the android? If not, how can
they be trusted to provide accurate answers?

These are not official.
as to accuracy, nobody can assure you it will give the right answers. But that's true for all pieces of software.

Exactly. And, if you recall our earlier discussion, there are even cases where the TI software is incorrect due to rounding/precision errors.

Also, if I'm reading it right, the app uses a Rom as it's backbone. A Rom is basically a dump of the Flash ROM memory, so the app is really using TI's O/S and algorithms, and the author just creates the interface and the code to read/use the Rom. So you can trust it to be correct as much as you trust the calculator itself. It's like any of the third-party emulators you see on ticalc.org.

as long as the emulator itself doesn't add bugs. Although bugs on the
emulator will most likely cause crashes of the app, not incorrect
results of calculations.

But, again, no software is 100% bug free. The Bugzilla bug tracking
system, used most notably in the development of Firefox, Thunderbird
and all other Mozilla products, returns "Zarro boogs" when no bugs are
found on a specific search. The statement is something like: just
because you can't find them doesn't mean they're not there.

PS: most of my work consists in tracking acessing and fixing bugzilla
issues; "Zarro boogs" is something I almost never see.

Thank you. Sounds like a good program. My concern was that it would
be an imatation full of bugs. Being able to trust it as much as the
calculator itself is good enough for me.
