Everything a fitness watch does — from your finger
The finger delivers a cleaner biometric signal than the wrist, so Titan II measures more accurately while staying invisible on your hand and out of your day.
Deeper sleep insights
Track sleep stages, latency and efficiency to understand exactly how well you rest — and how to rest better.
24/7 heart rate
Continuous heart rate and resting HR trends captured from your finger, where signal quality is highest.
Heart rate variability
HRV is one of the best readiness signals your body gives — Titan II watches it all night.
Daily recovery score
Wake up to a single readiness score that tells you when to push and when to hold back.
All-day activity
Steps, calories, active minutes and workouts — automatically detected without lifting a finger.
Blood oxygen (SpO2)
Overnight SpO2 monitoring helps you spot breathing disturbances and altitude effects.
Skin temperature
Nightly temperature trends reveal early signs of illness, stress and cycle changes.
Stress & mindfulness
See how your body responds to stress and use guided breathing to bring it back down.
Feather-light comfort
Aerospace-grade titanium weighs just 4 grams — light enough to forget you're wearing it.
Up to 7-day battery
A full week of tracking on a single charge, then back to 100% in under 90 minutes.
Water resistant to 100m
Shower, swim and sweat freely — Titan II is sealed and built to keep going.
Silent smart alarm
A gentle vibration wakes you at the lightest point of your sleep cycle, not the whole room.
A lab of sensors, hidden in titanium
We packed a research-grade sensor array into a band thinner than a wedding ring. Every reading is processed on-device and encrypted before it ever reaches your phone.
- Medical-grade infrared and red LED sensors
- 3-axis accelerometer for motion & sleep detection
- Negative-temperature-coefficient skin sensor
- Bluetooth 5.2 low-energy sync to iOS & Android
Your body, translated into a plan
Raw data is only useful if you know what to do with it. The Titan app turns your sleep, recovery and activity into simple, personalized guidance you can act on each morning — with no subscription required.

Frequently asked questions
What are the AI Coach and Protection Plan add-ons?
Both are optional monthly add-ons at $4.99/month each, billed separately after your order. AI Coach turns your ring's data into daily, personalized guidance — sleep, recovery, readiness, stress, and activity coaching that adapts as your trends change. The Protection Plan gives you one free replacement ring per year that covers theft, loss, and damage — no questions asked. Cracked it, lost it, or had it stolen? We ship a new ring in your size and finish. Add either or both, and cancel anytime from your account.
How long does the battery last?
Up to 7 days on a single charge, with a full 90-minute charge from empty. The magnetic charging dock takes up minimal space on your nightstand.
Which sizes are available and how do I find mine?
Titan II comes in US sizes 7 through 13. Grab the $20 sizing kit to try a few fits at home — you get $20 back as credit toward your ring, so it effectively pays for itself.
Is it waterproof?
Yes. Titan II is water resistant to 100 m (10 ATM), so you can wear it in the shower, pool, and ocean without worry.
Does it work with my phone?
Titan II pairs over Bluetooth 5.2 with the free companion app on iOS and Android.
What does shipping and returns look like?
Shipping is free on every order. If it is not the right fit, return it within 30 days for a full refund, and every ring is backed by a 2-year warranty.
