How does Sahha derive a sleep score without a wearable?

Sahha enables enterprises to leverage sleep tracking without requiring users to wear a smartwatch or fitness band. Using just a smartphone, we estimate key sleep metrics like total sleep time, sleep consistency, sleep debt, and circadian alignment. If users have wearables, we provide deeper insights into sleep continuity, mental recovery, and physical recovery. By leveraging both smartphone-based and wearable-integrated tracking, enterprises can provide sleep insights to a wide range of users, ensuring inclusivity and scalability.

📱 Smartphone-Only Tracking

Accessible to all users without additional hardware. Tracks 4 core sleep metrics through passive monitoring.

⌚ Enhanced with Wearables

Deeper insights with 7 total metrics including sleep stages and recovery analysis for users with devices.

How does Sahha track sleep without a wearable?

Most sleep trackers measure heart rate and movement to infer sleep stages which provide valuable information about the sleep session. However, not everyone has or wants to use these trackers. Sahha offers a data-driven alternative by enabling sleep tracking via smartphones. This approach allows enterprises to integrate passive, scalable sleep tracking into their applications and services, enabling valuable health insights without requiring additional hardware.

Smartphone-Based Sleep Metrics

⏱️ Total Sleep Time

Estimate sleep duration by detecting long periods of phone inactivity. If a phone isn't used between 11 PM and 7 AM, we infer about 8 hours of sleep.

📊 Sleep Regularity

Track how stable bedtime and wake-up time are over days and weeks, providing insights into sleep schedule consistency.

🌅 Circadian Alignment

Assess how well sleep aligns with natural circadian rhythms and environmental cues like sunrise and sunset.

😴 Sleep Debt

Calculate accumulated sleep deprivation to help users recognize when they need to catch up on rest.

What additional insights do wearables provide?

For users who have sleep trackers connected, Sahha provides a more comprehensive sleep analysis, adding more key aspects of sleep health derived from sleep stages:

Enhanced Wearable Metrics

🔄 Sleep Continuity

Detect night-time wake-ups, duration of wakefulness, and sleep disturbances for a clearer picture of sleep fragmentation and stability.

🧠 Mental Recovery

REM sleep tracking for cognitive processing, memory consolidation, and emotional stability assessment.

💪 Physical Recovery

Deep sleep analysis for muscle growth, tissue regeneration, and immune function support during night-time recovery.

Why is smartphone-based sleep tracking useful?

Scalability & Accessibility: Sahha's smartphone-based approach ensures that enterprises can offer sleep insights to all users, including those without wearables. While wearables provide additional details, smartphone-based tracking remains a highly accessible and cost-effective way to measure sleep health trends. This enables companies to reach a broader audience without requiring users to invest in specialized hardware.

This approach makes Sahha ideal for:

✓ Scalable wellness solutions

✓ Employee health programs

✓ Consumer sleep tracking apps

The Bottom Line

Sahha makes sleep tracking flexible, inclusive, and actionable. Whether Sahha’s sleep score is based on smartphone-based tracking or enhanced with wearable data for deeper insights, it provides meaningful sleep analysis that helps users improve their rest and overall well-being. Enterprises can leverage the sleep insights in wellness platforms, healthcare applications, employee well-being programs and more, to drive engagement and improve health and business outcomes at scale.
