Development of an application for iOS and Android

Need to develop a mobile application for workouts.
The application will include:
- A main page with cards for daily activity: Steps, distance, completed goals, number of workouts per week, number of calories consumed, adherence to the sports nutrition plan.
- A training diary page: A calendar where users can enter and record their workouts. The application will contain a ready-made list of exercises and the ability to add their own exercises. Exercises can be selected for a specific day and record the number of sets and weight used during workouts. In addition to recording workouts, the diary should also have functionality to calculate how long the workout lasted, a timer for rest between sets, prepared examples of exercise techniques, as well as access to statistics showing the person's progress in workouts (working weight, total tonnage lifted, etc.)
- A calorie calculator page: Here, users will have the opportunity to track and calculate the calories and macronutrients of their diet. Initially, the application calculates the required calories and macronutrients for the user based on their weight, body fat percentage, and activity level. Then, the person creates meals, such as breakfast, and selects the food and weight they consumed. The application should have a ready-made database of popular products and their macronutrient values. Additionally, there should be an option for users to add their own products. There is also a question about functionality with artificial intelligence, where it can recognize what food is on the plate through the smartphone camera.
- A sports nutrition page: where there will be information about sports nutrition intake. The person selects the sports supplements they have, and the application will automatically generate a schedule for taking the selected sports nutrition throughout the day.
- A page for ready-made workout programs. When purchasing a workout program, the application automatically fills the training diary page with the necessary exercises and the required number of sets.
- An application settings page.

The functions of the main page and training diary will be free.
The functions of the calorie calculator and sports nutrition will be available via a monthly subscription.
Additionally, workout programs will be purchased by users separately, regardless of whether they have an active subscription.

I will say right away - I do not know the market prices for app development, so please propose your terms, and I will consider them based on my budget.
