Rest^Better

Rest^Better is a SwiftUI iOS application that helps users calculate their ideal bedtime based on desired wake-up time, desired sleep amount, and daily coffee intake. It uses a machine learning model to recommend the optimal time to go to bed for a well-rested day.

Features

• Select your desired wake-up time using a DatePicker.
• Adjust the number of hours of sleep you want via a Stepper.
• Specify your daily coffee consumption.
• Calculate your recommended bedtime using a CoreML-powered prediction model.
• User-friendly SwiftUI interface with immediate feedback.

Technologies Used!

• SwiftUI (UI framework)
• CoreML (Machine Learning model integration)
• Combine (for state updates)
• Swift (Swift 5.7+)

How It Works

1. User selects their desired wake-up time.
2. Adjusts the desired sleep duration (in hours).
3. Inputs their daily coffee intake.
4. Taps the Calculate button to see the recommended bedtime.
5. The app uses the SleepCalculator.mlmodel to process the input and predict the optimal bedtime.

Running the Project

1. Clone or download the project.
2. Open the .xcodeproj or .xcodeworkspace in Xcode.
3. Make sure the target device is set to a simulator or physical device running iOS 15+.
4. Build and Run (Cmd + R).

Notes

• The machine learning model provided is a simple regression model predicting sleep needs. It may not be medically accurate but serves as an educational tool.
• This project is inspired by Paul Hudson's "Hacking with Swift" 100 Days of SwiftUI curriculum.
