A note from the developer

Hi, I’m Moonshot, the developer of GutBrain.
This app began with a deeply personal experience. In my early twenties, an irregular lifestyle left me battling chronic headaches, breakouts, hair loss, and insomnia—and the answer turned out to lie in something I’d overlooked: gut health.

By caring for my gut, I reclaimed my well-being, and I built this app to share that change with you. I hope GutBrain becomes a dependable companion on your journey toward a healthier gut—and a more vibrant life. Thank you.

— Moonshot, Developer of GutBrain
