I was going to leave a snarky comment about "reverse engineered disassembler" but then accidentally saw the username. What do you mean by that?

I would assume he's referring to the MSP430 disassembler built into the watch so you can reverse engineer the watches hardware, as it says in the article.

That was awesome but that is a reverse engineering disassembler (a bit redundant when the GoodWatch guy wrote the code to begin with but ...).

A reverse engineered disassembler would be a disassembler that has been reverse engineered itself, which was not what the article said.

It confused me, too.

You might want to be more mindful of snarkiness, with Google's help you'll know why, I'd hope.
