MVP Complete, but How do I launch?

I build a companion app over the weekend to dip my feet in the launch water. To be honest, I don't know what I was afraid of.

I built this app in flutter the previous year but never released it to the Play or iOS stores.
It was interesting to see how far I've come.

Note: This app is buggy for iOS.
Its purpose was to show me what to expect in launching a PWA. I haven't removed the bugs due to my focus on the main app.

Problem: Publishing
Solution: Publish something smaller.
