I wouldn't rely on anecdata from HN posters, who may or may not be representative of your potential market. Try and gather some data and see what it says, e.g. spend $5 on some facebook ads for your not-yet-existant product, and see the breakdown of OS's that hit your landing page.

Well, if the OP gets 100 actual responses (as opposed to secondary discussion posts), then that anecdata actually is data.

Given:

* the nature of the described app

* that its functionality appears to be scratching an itch the OP has

* that the OP is a member here

* the OP asking the question here

..it doesn't seem to be far fetched to think that the posters here are at least somewhat representative of the potential market.

Yes, it's a good point to do such market research. Will need to carefully structure the ads, to not skew the results (e.g. because users from one platform are cheaper per click, and thus will be preferred by Facebook)
