iOS Fitness Tracker with Meal Plan

I'm looking for a fitness tracker app in google sheets. This app should primarily focus on providing a meal plan with macros calculator. The meal plans should be pre-defined, with no support for custom meal entries. While the app will include features such as a bodyweight tracker and a training plan, these should be secondary to the primary focus on the meal plan.

Ideal skills and experience for this project:
- Experience in developing fitness-related applications
- Knowledge of nutrition and meal planning
- Ability to create user-friendly interfaces
- Skills in integrating macros calculators into apps
