Thank you! I definitely considered doing something like that, however — the amount of work required to crowd source the data would be significant. There would be a “chicken & egg” problem — the app wouldn’t be useful to first users, and without the first users, there wouldn’t be enough data to make it useful for everyone else — so this would require a fairly large marketing campaign to get off the ground. But — one day I may still do it :)

There's hardly a chicken & egg problem if you already had a bunch of happy users. Just display "no data available" on the first day, and have a banner in the app explaining the situation, and ask them to contribute today's data. You'll most certainly get a handful of users who want to help. After 3 or so days of this, the problem will be solved.
