Fitness App - PT - Schedule, Meal Plan Detail

I'm working on a personal project for a while, an app for personal trainers and their customers to work together, track workouts and nutrition together. It's an ongoing project, it's constantly changing a bit. I mostly do it because I think there's no good app currently out there which does this (at least from what I know, maybe I'm wrong) and I'm interested in the area. Currently, I'm working on IA, UX, and UI at some point I might start coding it or find someone who can help me, or it might just remain a concept only.
This page shows the schedule for the Personal trainers and a meal plan detail page where they can set up details for different meals (ex. breakfast), define calories, macros, etc... and manage meal suggestions.
Some previous views can be found here (all WIP mocks, which changed a bit since then).
