BoardingBot https://boardingbot.boorgle.com
Is a tool I made few weeks ago over 4 days. I started it as a Facebook chat bot which sends TestFlight invitations and then realized it's also worth turning it into a more complete tool which creates a website and invitation request form which automatically sends TestFlight invitations.
It was featured in ProductHunt and I was generally surprised with the positive feedback.
I'm wondering if it's worth investing more time into it...
