Sleep Phase Wake App for WatchOS

Goal: wake up easier while less sleep, increase sleep quality

SwiftUI + MVVM WatchOS App for waking up using Sleep Phase detection via accelerometer (very basic shaking detection for now)

Later Apple's native HKCategorySleepAnalysis will be added for detection enhancement

App Development Steps for creating of MVP (Minimum Valuable Product):

1. UI-part:

   • inactive state screen (selection wake up time);

   

   • active states screen(showing processing screen);

   

   • finish screen (wake up message);

   

   • MVVM-arhitecture applying;

2. Create processing part of the app:

   • background-runtime execution for some period of time(30 minutes is maximum possible duration - OS restrictions);
   • background states handling;
   • making possible to have some calculations several times/minute(every second for now);

3. Sleep Phase basic calculation(using only acelerometer data for now):

   • measure moves via acceleration;
   • use first move per Wake Up interval as a trigger for Wake Up(used total acceleration for this need);

Next Steps:

1. Beta-testing:

   • sharing between several internal testers;
   • approve the idea by receiging more positive feedbacks then negative;
   • fixing of minor bugs;

2. Additional UI-functionality;

3. Redesign;

4. SleepPhase algorhytm detection improvements;

5. Alpha-testing;

6. Companion iOS-App - showing detailed graphs (with sleep stages and/or sleep quality and/or sleep durations - HealthKit);

Ideas for further Sleep Phase Detection:

• use number of moves/hour for Sleep Phase detection
• try to make marks per wake ups;
• use Heart Rate for Sleep Detection;
