Overall verdict

  • Sleepytime.info is a good, free, no-frills tool for quickly calculating optimal wake-up or bedtime schedules based on 90-minute sleep cycles, making it useful for casual sleep planning but not a substitute for in-depth sleep tracking or medical advice.

Why this product is good

  • Simple, easy-to-use interface with no sign-up required
  • Based on the science of 90-minute sleep cycles to reduce grogginess
  • Completely free to use
  • Quick results for both 'wake up at' and 'go to sleep at' calculations
  • No ads or intrusive design cluttering the experience

Recommended for

  • People wanting a quick way to time their bedtime or alarm
  • Students or shift workers adjusting irregular sleep schedules
  • Anyone curious about sleep cycle theory without needing detailed tracking
