Custom Fitness Workout Plan App -- 2

I want to bring “Good to my life” to the stores as a health-and-fitness mobile app focused purely on workout plans. The goal is a clean, intuitive experience that helps users choose or build routines, schedule them, and track completion without extra distractions.

Here’s what I need:

• Workout plans – the heart of the app. Users must be able to browse preset routines and create, edit, or duplicate their own plans. A simple calendar view for scheduling sessions and a progress log that checks off completed workouts will cover the first release.

Everything else—nutrition or broader activity tracking—can wait; I prefer to keep v1 lightweight, fast, and maintainable. Please target both iOS and Android; the framework is up to you, as long as the UI feels native and performance is smooth.

Deliverables and acceptance:
1. Clickable UI prototype (Figma, Sketch, or similar) approved before development starts.
2. Production-ready mobile app build for iOS and Android with the workout-plan feature working end-to-end.
3. Source code, brief setup notes, and a short Loom or screen-share walkthrough so I can run the project locally.

If you have proven experience shipping fitness apps or strong portfolio pieces in React Native, Flutter, Swift/Kotlin, let me know—code quality and a user-friendly design are my top priorities.
