Ronnie sees everything.
Ronnie rates your V-taper, leanness, symmetry, and estimated body fat — plus a score for every major muscle group — then tracks the change week over week. He remembers your last scan, and he'll say so.
Stop guessing whether you're making progress. Ronnie will tell you — every week, whether you want to hear it or not.
Scores that mean something
V-taper, leanness, symmetry, a body-fat estimate, and a 0–100 score for each major muscle group — the metrics that actually describe how you look, not a single number on a scale.
Progress you can see
Every metric shows the change since your last scan. A cut, a bulk, or a brought-up muscle group shows up as a number, not a vibe.
A rank to chase
Your scores roll up into a physique tier from Lifter to Champion. The ladder turns months of slow progress into a goal you can actually feel yourself climbing.
How it works
Snap a front photo
One clear, front-facing photo in the app — no measuring tape, no calipers, no special hardware.
Get the verdict
Ronnie returns your physique scores, a body-fat estimate, and a per-muscle breakdown in seconds.
Re-scan weekly
Scan again each week and watch your numbers — and your rank — move as you train and eat.
What people use the scan for
A breakdown for every muscle
See which groups are leading and which to bring up, so your training targets your actual weak points instead of your favorites.
Weekly progress deltas
Every score shows the change since your last scan — visible proof your work is paying off, or a nudge when it isn't.
Private by design
No Face ID, no facial recognition, no biometric data. Your photo is used only to compute your scores and is never sold.
Pairs with your plan
The weak points Ronnie finds feed straight into your training, so every session has a reason behind it.
What Ronnie actually measures
A FERAL scan reads four things at the whole-body level: your V-taper (the shoulder-to-waist ratio that defines an athletic silhouette), your leanness (how much muscle definition and conditioning is visible), your symmetry (left-to-right and upper-to-lower-body balance), and an estimated body-fat percentage.
Then it goes deeper. Each major muscle group — chest, back, shoulders, arms, core, and legs — gets its own 0–100 development score. That's the part that changes how you train: instead of "do more," Ronnie tells you "your legs are lagging your upper body by twelve points." You can take exactly that into your next AI-generated workout.
Why a photo beats the scale
The scale can't tell muscle from fat from water. You can drop three pounds of water and feel like you're winning, or add three pounds of muscle and panic. A physique scan looks at what the scale can't: the actual conditioning and proportions you see in the mirror.
That's also why it pairs naturally with nutrition. Your weight is downstream of what you eat — so the scan tells you what your body looks like while FERAL's calorie tracker handles the inputs that move it.
How accurate is it, really?
Ronnie's scan is an AI estimate built to track trends over time — it's not a replacement for a DEXA scan or skinfold calipers, and we won't pretend otherwise. What it is excellent at is consistency: scan in similar lighting and the same pose each week and the week-over-week deltas become genuinely reliable signal.
Think of him like a coach with a scoreboard, not a doctor. The absolute number matters less than the direction it's moving — and the direction is where all the motivation lives.
Common questions
How accurate is the body-fat estimate?+
It's an AI estimate designed to track trends over time, not a lab measurement like a DEXA scan. Use the same lighting and pose each week and your week-over-week changes become very meaningful.
Do I need any special equipment?+
No — just your iPhone camera and a front-facing photo. No calipers, scales, or tape measures required.
What happens to my photos?+
Your photo is processed securely only to compute your scores. FERAL does not use facial recognition or store biometric data, and your photos are never sold. See our Privacy Policy for the details.
How often should I scan?+
Once a week is the sweet spot — frequent enough to see progress, spaced enough that real change shows up between scans.
What's a physique rank?+
Your scores roll up into a tier from Lifter to Champion, with sub-tiers in between. As your scores improve, your rank climbs — a simple way to feel long-term progress.
Can the scan tell me what to train?+
Yes — Ronnie's per-muscle scores highlight your weak points, and you can take that straight into a FERAL workout built to bring them up.
