You can intuit your macros. You can't intuit your physique.
AI physique analysis that scores six muscle groups and names your weakest link. For lifters who actually want to know if their body is changing — not another mirror, not another guess.
two free check-ins. scored across 6 muscle groups. your weakest link, named.
/// AI PHYSIQUE VERDICT
six muscle groups scored. weakest link named. body fat % and FFMI in every result. quantified perception drift — not vibes.
/// TRACKS CHANGE OVER TIME
your mirror lies to you. tracks real progress across check-ins. surfaces what you can't see. builds a log nobody else can fake.
/// BUILT BY A LIFTER
not a wellness company. not a self-help app. built by Matthew Fierro — someone who trains, not someone who talks about training.
FROM PHOTO TO
PHYSIQUE VERDICT.
Two free check-ins give you a baseline and one follow-up. Use a quick scan or the full 3-angle protocol for either one.
- 01
CAPTURE
Take a quick single-angle photo or run the guided front, side, and rear protocol.
- 02
ANALYZE
On-device vision measures pose and photo conditions. A downscaled copy is sent to Anthropic for analysis.
- 03
COMPARE
Review six muscle-group scores, your weakest link, and feedback you can compare against future check-ins.
TWO FREE. THEN PRO.
No payment is required for your first two check-ins. Choose a plan in the app only if the verdict earns another scan.
Prices and trial availability may vary by storefront. Specimen is informational physique analysis, not medical advice. Pro unlocks unlimited check-ins after your two free scans.
