The wellness industry sold us hardware — bands, rings, watches. But the most powerful sensor for everyday recovery is already in your hand. EyeZenith is camera-first: your phone is the scanner.
Why camera-first wins
- No purchase — nothing new to buy or justify.
- No charging — your phone is always ready.
- No friction — the camera is always with you, so the habit survives a busy day.
What a camera can read
A front-camera test scores eye fatigue in about 30 seconds. And with camera-PPG — a finger over the rear camera with the torch on — your phone can even estimate HRV, the same recovery signal people buy expensive bands for.
Wearables as a bonus, not a requirement
If you already wear an Apple Watch, your HRV flows in automatically. If you do not, the camera covers it. Either way, you are never blocked from checking in.
The best wearable is the one you already own — and never forget to wear.
Lower friction, higher consistency
Recovery tracking only helps if you actually do it. Camera-first removes the barriers, and consistency is where the real benefit lives.
