I built NutrientOS, an iOS nutrition app that goes beyond calories and macros

Hey guys!

I’m the developer of NutrientOS, a nutrition and training app for iPhone.

It tracks calories and macros, but also goes deeper into micronutrients, food quality, satiety, restaurant foods, meal scanning, workouts, and nutrition trends.

There’s also a 1-week free trial of Premium right now.

Would love feedback from other iOS devs on the UI, onboarding, performance, or subscription flow.
