There is an android app on the google play marketplace, but it is not from the anova folks and it costs $2. I haven't purchased it, because I already have my own list of "if you're cooking foo, set the temperature to bar" commands in my (analog) recipe notebook.

Everything else about the newer anova is great. I have both a new-style and old-style (anova one) from them, and they're both cool. Now that I have the newer one with the adjustable clip, I intend to keep that in my kitchen for simple sous-vide stuff (steaks, chops, eggs, etc) and build an insulated enclosure out of a cooler for the One, so I can tackle bigger cooking projects.

The app isn't out yet but the Bluetooth API is fairly simple: https://github.com/neilpa/circulate and I ended up hacking together a very basic app in node.js in about 3 hours.

I don't know, unfortunately.
