H-Core Helps You Sleep Better — Track and Improve Sleep Quality
Understand your sleep — and actually improve it
If you often wake up tired despite sleeping enough hours, the issue is usually quality, not quantity. H-Core analyzes every sleep stage — deep sleep, REM, light sleep — and nighttime SpO₂, helping you see the exact problem and take action.
The challenges you face
Sleeping enough hours but still waking up exhausted
8 hours of light sleep doesn't equal 6 hours with sufficient deep sleep. Without knowing which stage you're in, you can't know what needs to change.
Unclear which habits are affecting sleep quality
Afternoon coffee, phone screen before bed, or work stress — which one is actually affecting your sleep? Long-term data from H-Core helps you find the correlation.
Concerned about sleep apnea
Sudden and repeated SpO₂ drops during sleep can be a sign of sleep apnea. H-Core monitors SpO₂ continuously throughout the night and alerts you to abnormal patterns.
