Sahha adds sleep tracking back to iOS phone apps and improves it by making it passive, research backed and GDPR compliant. Devs, get accurate sleep insights without wearables using just an iPhone, backed by science and seamlessly integrated with HealthKit.
Hey ProductHunt! I'm Aleks, founder of Sahha. We're excited to launch our Sleep API that brings back and enhances sleep tracking capabilities for iOS developers.
When iOS 18 rolled out, it unexpectedly removed critical sleep timing estimates that countless developers depended on for their health and wellness apps. The result? A huge segment of iOS users lost access to the sleep-related insights they’d come to rely on, including Sahha Sleep Scores and biomarkers, which largely leveraged Apple’s Sleep Estimates via HealthKit.
Our Solution: We built the Sahha Sleep API for iOS—a scientifically validated, phone-only method that generates accurate sleep biomarkers and scores without requiring wearables that uses (drum roll) largely HealthKit data! Essentially, we’ve replaced (and even improved upon) Apple’s removed features by tapping into HealthKit phone sensor data. In late December (just before Christmas), we deployed our fix, ensuring that over 80% of our customer iOS user base—who rely solely on their phones—continued receiving reliable sleep scores & biomarkers without any extra effort on their part, woohoo!
You can try it out on our demo app ('Sahha' on the iOS App Store - linked on this product) or get started building with Sahha by visiting our docs.sahha.ai

P.S massive shoutout to the tech, product and especially the data/science team for pulling through on this so quickly, you know who you are!
Passive, phone-only sleep tracking is a huge advantage for users who don’t rely on wearables. Excited to see how this evolves!
Congratulations on reintroducing sleep tracking with such a strong focus on user privacy and research. How do you ensure the accuracy of the sleep data collected passively, and what metrics can users expect for their sleep insights?
I’ve always thought that wearing a wearable device to track sleep quality isn’t very convenient, but this product can scientifically monitor sleep quality without the need of any wearable device, which is really amazing.
This looks really exciting, @aleksdahlberg ! Congrats on the launch!
Congrats on launching Sahha Sleep API. Love how you turned a challenge into an opportunity by building something even more powerful. Wishing you success!
