Timeshifter

Timeshifter is a mobile app designed to help users overcome jet lag and adapt to night shift work by harnessing neuroscience and circadian rhythm research. Originally created for astronauts and elite athletes, Timeshifter brings advanced sleep and light exposure strategies to frequent travelers, pilots, flight crews, and shift workers.

Built on the science of circadian rhythms, the app creates personalized plans to reduce jet lag symptoms and align your internal clock to a new time zone or schedule. By using factors like chronotype, flight details, and sleep patterns, Timeshifter provides precise recommendations on when to seek or avoid light, sleep, caffeine, or melatonin—making transitions smoother and healthier.

Features:

1. Jet Lag Plans
   Personalized schedules to minimize or eliminate jet lag based on your itinerary, sleep preferences, and chronotype.

2. Shift Work Plans
   Tailored guidance for shift workers transitioning between day, night, or rotating schedules.

3. Scientifically Backed Algorithms
   Developed with leading sleep researchers including Dr. Steven Lockley from Harvard Medical School.

4. Pre-Travel Preparation
   Plans start before your journey to help you gradually shift your circadian rhythm in advance.

5. Real-Time Guidance
   Simple, actionable prompts such as “seek light,” “avoid caffeine,” or “take a nap now.”

6. Chronotype-Based Personalization
   Adjusts each plan based on whether you’re a morning or evening person.

7. Minimal Cognitive Load
   Visual interface and clean instructions eliminate guesswork or information overload.

8. Offline Access
   Once your plan is downloaded, no internet is required during your trip or shift.

9. Melatonin Recommendations
   Optional, evidence-based suggestions on optimal timing for melatonin intake (if used).

How It Works:

1. Download the App
   Available on iOS and Android platforms.

2. Create Your Profile
   Enter your chronotype, sleep patterns, and preferences.

3. Input Travel or Shift Details
   Add your flight itinerary or shift schedule for personalized recommendations.

4. Receive Your Plan
   The app generates a schedule with guidance on light exposure, sleep, caffeine, and melatonin.

5. Follow Notifications
   Throughout the day, Timeshifter sends push notifications to guide you in real time.

6. Adjust as Needed
   If your plans change, Timeshifter quickly recalibrates your schedule.

  Effective for both jet lag and night shift transition.

• Proven Results
  Trusted by astronauts, Olympic athletes, and frequent flyers.

Drawbacks:

• Limited Free Use
  Only one jet lag plan is free; further access requires payment.

• No In-App Sleep Tracker
  Does not track your actual sleep; works purely on schedule adherence.

• Requires Manual Input
  Users must enter flight or shift details—no automatic syncing from travel apps or calendars.

• Not a Medical Tool
  While based on scientific research, it is not a substitute for professional medical advice on sleep disorders.

Comparison with Other Tools:

• Sleep Cycle: Focuses on sleep quality tracking, not circadian adjustment. Timeshifter is specialized for jet lag and shift work.

• Re-Timer Light Therapy: Offers light-based devices; Timeshifter provides the timing strategy for such tools.

• Calm or Headspace: Provide sleep meditations; Timeshifter gives proactive, science-driven sleep schedule plans.

• WHOOP / Oura Ring: Great for physiological tracking; Timeshifter enhances circadian alignment with schedule optimization.
