First launch ever for my mobile app... How do you stay sane on launch day?

Hey Product Hunt! I’m Mya, the independent creator behind SafeMix. We just officially went live, and I am currently glued to my keyboard.

SafeMix is a clean, ad-free utility that checks real-time interactions across prescriptions, supplements, and vitamins. The upcoming launch on this page is just the beginning of the journey, and we’re keeping our launch tight by onboarding a tiny cohort of 150 founding members so we can build out the next phase directly alongside our users.

I’m a total beginner to the launch process, so I’d love to open up a simple conversation with the community.

If you’ve been through a software launch before, how do you handle the day-one noise and keep focused on actual user feedback? And if anyone has a chance to look at our page, what is one thing we could make clearer about our mission?
