COSI is an Ambient Comfort Intelligence system that learns your physiological preferences and automatically adjusts your environment — temperature, lighting, and sound — to keep you in your comfort zone.
By combining data from your body (skin temperature, stress levels, heart rate variability) with your environment (room temperature, humidity, light intensity, sound levels), COSI calculates your real-time comfort score and takes action before you even notice you're uncomfortable.
To get started you just need the COSI app — no hardware purchase required.
For full functionality, you'll want:
You can also connect existing smart home devices you already own, including Govee lights and Google Nest thermostats, and Apple Watch or Fitbit for physiological data.
COSI combines your physiological signals — skin temperature, EDA stress level, and HRV — with environmental readings — room temperature, humidity, light intensity, and sound level — to calculate a real-time comfort score from 0 to 100.
The higher the score, the more aligned your environment is with your body's current needs. Over time, COSI learns your personal preferences and becomes more accurate at predicting your comfort baseline.
A score of 70+ is generally considered comfortable. Below 40 typically triggers automatic adjustments (if you have automations enabled).
Yes. Your physiological data never leaves your personal Firebase database. It is never sold, shared with advertisers, or used to train AI models without your explicit consent.
We do not use any third-party analytics or advertising trackers. We do not run Google Analytics, Facebook Pixel, or any ad network on COSI. See our Privacy Policy for full details on what we collect and how it's used.
COSI Free gives you the comfort score, basic environment monitoring, and 7 days of history. No credit card required.
COSI Pro ($9.99/month or $99/year) adds:
You can cancel anytime from Profile → Subscription → Cancel Plan. Your Pro access continues until the end of your current billing period. No partial-month refunds are issued, but you won't be charged again after cancellation.
Yes. You can use COSI with just the app and connected smart home devices. The Band provides the physiological data layer that makes comfort scoring most accurate, but all environmental monitoring and automation features work independently.
You can also connect an Apple Watch or Fitbit to provide physiological data without the COSI Band.
Go to Devices → Add Device → Govee. You'll need your Govee API key:
Go to Profile → Account Settings → Delete Account. You'll be asked to confirm with your password. This permanently deletes all your data — comfort history, device connections, settings, and your account — within 30 days.
This action cannot be undone. If you're having issues with COSI, please contact us at hello@somacomfort.com before deleting — we'd love to help.
Our team is happy to help. Reach out and we'll get back to you within one business day.
