The Overview
SILO listens while you live — through the night, through the workout, through the ordinary Tuesday. Sleep, heart rate, movement and recovery, distilled into one score you can act on each morning. No screen on your wrist. No charging every night. Just a ring.
Capabilities
Precision sensors, seated in titanium, reading the signals that matter — day and night.
Continuous optical heart-rate tracking, from resting baseline to peak effort.
Stages, duration and quality — wake to a clear picture of how you actually rested.
Steps, distance and energy burned, counted quietly in the background.
SpO₂ insights that add depth to your sleep and recovery picture.
Trend-level blood pressure insights to help you understand your patterns over time.
Skin-temperature variation tracking — an early signal your routine is shifting.
Every metric, synced to a clean dashboard on your phone. Your data, decoded.
Four grams of titanium. Water resistant. Days of battery. You’ll forget it’s on.
The SILO App
The ring gathers. The app explains. Open your phone to a single daily readiness score and every trend beneath it.
Your readiness score condenses sleep, heart rate and recovery into a single number — so you know whether today is for pushing or restoring.
Weekly and monthly views reveal the direction of your health, not just yesterday’s data points.
The ring holds days of data and syncs over Bluetooth whenever your phone is near. iOS and Android.
In the Wild
The Philosophy
Understand sleep, rest and daily patterns. Know when your body has restored — and when it’s still asking for more.
Track movement, heart rate and activity with precision, and see how today’s effort shapes tomorrow’s capacity.
Monitor wellness trends over months, not moments. Small signals, observed early, compound into a longer story.

Questions
Precision optical and temperature sensors on the inner band read signals from your finger — where they’re strongest — around the clock. The ring processes this data and syncs it to the SILO app, which turns it into scores, trends and daily insights.
Yes. The SILO app for iOS and Android is your dashboard for everything the ring measures. Syncing happens automatically over Bluetooth, and the ring stores several days of data on its own if your phone isn’t nearby.
Heart rate, sleep stages and quality, steps, calories and distance, blood oxygen insights, blood pressure insights, skin temperature variation, and a daily readiness score built from all of the above.
SILO is water resistant to IP68 — showers, washing up and swimming are all fine. We’d suggest removing it for diving or extended time in hot water like saunas.
Smart ring sizing differs slightly from jewellery sizing, so if you’re unsure, choose the “sizing kit first” option. We’ll send a free plastic sizing kit before your ring ships, and unworn size exchanges are always free.
UK orders arrive in 2–4 working days with free tracked delivery. International delivery times and costs are shown at checkout.
No. SILO is a wellness device designed for lifestyle insight, not diagnosis. Its measurements shouldn’t replace professional medical advice, and if you have concerns about your health you should always speak to a doctor.
