I'm surprised this is being downvoted. Again and again we've seen really smart people who made a great photo app try to bring their approach to something that's genuinely hard for reasons that go beyond how to write code or build a SaaS business, and leave a trail of wreckage in their wake. Healthcare, education, civic life, etc. are all extremely valuable problems, but only if you actually get it right.

There are counterexamples, and they'll all tell you that the code was the easy part.
