Match the conditions
On-device guidance checks framing, distance, light, and focus as you shoot.
Private beta for iPhone
Make every hair photo comparable.

Why Baseline
A fair comparison starts with the same photo.

Capture your front hairline and both temples through one simple routine.
Compare like with like
Review matching angles over time instead of digging through your camera roll.
Private by design
Your hair photos stay on your iPhone.
No account. No cloud photo analysis. No customer-image model training.
