Honest comparison
Ray vs. Apple Watch
Apple Watch is a tiny computer you charge every night. Ray is a 7-gram health tracker that powers itself from light. Different products, different lives.
The short answer
If you want notifications, apps, calls, and a screen on your wrist — get an Apple Watch. If you want continuous health tracking that disappears on your wrist and never needs charging — get Ray.

Reasons to choose Ray
- More than 5× lighter. 7 grams vs Apple Watch's ~38. You forget you're wearing it.
- Never needs charging. No bedside puck. No "watch died, no run today."
- Designed for long ownership. Ray has a target useful life of 10+ years and no charging port.
- Half the price up front. $199 vs $399+ for a base Apple Watch.
- No notifications. Ray is a calm option for people who do not want another screen competing for attention.
- Looks like jewelry, not a computer. Slides under a shirt cuff or a watch.
Reasons to choose Apple Watch
- Apple Watch has more sensors (ECG, blood oxygen, fall detection).
- If you actually want notifications, calls, Apple Pay, music, or maps on your wrist — Ray cannot do that.
- Apple Watch has a screen. Ray does not.
- Tighter integration with iPhone for fitness rings and workout tracking.
The 5-year math
Ray costs $199 once. Apple Watch Series 11 currently begins at $399; optional services and any future replacement would add to that, but replacement timing depends on the owner.

Common questions
Can Ray replace my Apple Watch?
For health tracking, yes. For notifications, calls, apps, and a screen — no. They serve different purposes. Many of our buyers wear Ray on the opposite wrist from a watch, or wear it solo.
Does Ray do ECG like Apple Watch?
No, Ray does not do single-lead ECG. It tracks heart rate, HRV, and sleep stages continuously, which covers most cardiovascular wellness use cases.
Will Ray work with my iPhone?
Yes — there's a native iOS app. Ray syncs automatically when your phone is nearby.
Why is Ray so much lighter?
No screen, no battery for screen, no haptic motors, no speaker. Ray does one thing — track health — and the absence of everything else is what makes it feel like nothing on your wrist.
When does Ray ship?
Batch 2 is reserving now and ships in September 2026. Refundable any time before shipping.
Stop charging. Start wearing.
Ray is what Apple Watch could never be: a health tracker so light and so self-sufficient you forget it's there.
