Evimetra
Most people judge their skincare results by how they feel on a given morning. That is an unreliable metric: lighting shifts, hydration levels fluctuate, and subjective perception drifts. A measurement made under different conditions than the previous one tells you nothing about the product or routine — it tells you about the conditions.
Evimetra is a skin tracking app designed to remove that variable. It sets a personal baseline from your first photo capture, then guides you back to exactly the same distance, angle, light, and framing every week. The comparison is only valid when the conditions are consistent, and the app enforces that consistency automatically.
How the 0–100 wellness index works
After each capture, Evimetra returns a 0–100 wellness index calculated from the re-captured area. The score reflects quantified change over time — not a snapshot impression, not a filter. Because each session is taken under identical conditions, week-on-week differences in the index correspond to actual differences in what the camera sees, not to differences in ambient light or phone distance.
The app covers four areas: Face & skin, Hair & scalp, Nails, and Smile. An AI mentor provides personalized advice based on the data collected across those areas.
What consistent conditions actually change about your data
Consider a typical scenario: someone photographs their forehead hydration under bright bathroom light on Monday, then under a window on Saturday. The two images are incomparable. Evimetra's guided capture eliminates this by locking the framing parameters before the shot is accepted. The result is a longitudinal dataset — a series of measurements that can be compared because they were collected the same way.
This matters for evaluating whether a serum, supplement, or routine is producing a real effect rather than a placebo impression. Marketing claims cannot be tested against feelings; they can be tested against indexed, time-stamped measurements.
Privacy and data handling

Frequently asked questions
What is a skin tracking app?
A skin tracking app captures photos of your skin at regular intervals under controlled conditions and measures change over time using a numerical index. Evimetra uses a 0–100 wellness index calculated from weekly re-captures taken under identical distance, angle, light, and framing.
How does Evimetra ensure each photo comparison is valid?
Evimetra guides you to re-capture the same area every week under identical conditions — same distance, angle, light, and framing. It enforces these parameters before accepting a shot, so week-on-week differences in the wellness index reflect actual skin change, not variation in capture conditions.

Evimetra covers four areas: Face & skin, Hair & scalp, Nails, and Smile.
