Excellent delivery! The Home Inventory screens were developed with attention to the requested features and details. The item fields are organized nicely, and the edit and removal functionality makes the experience much better. Everything looks clean and professional.

I really liked the overall direction of the app. The class schedule is easy to follow, and the booking section feels simple and clear. The design has a nice fitness-focused look without feeling too busy. Communication was easy throughout the project, and the final result feels ready for the next stage.

The final Figma work gives us a clear picture of how the complete app should function. The onboarding, authentication, bird profiles, dashboard, records, reminders, and settings all have a consistent visual direction.
