I just want to add to the chorus of people saying they would pay for this. I too would be delighted to pay for this app. Looks AWESOME, thank you for creating it!
If I can offer a button nitpick - I suggest "Try it out for free!" in big text, and "Version 1.5.248.1, 2016-04-26" in small text. Maybe as simple as wrapping the version info in a <small> tag.
I agree 100%. It has gotten easier to turn a side project into a business.
My take is that it has gotten easier enough that fewer folks are pursuing VC, opting to bootstrap instead. It's not that fewer side projects are happening - more side projects are happening. Fewer of them need VC money to succeed/scale/generate meaningful revenue, so VCs are seeing fewer side projects.
