About this app

aXis turns your phone camera into a body-composition lab. Take a photo and AI estimates your body-fat percentage and 40+ body measurements — then syncs them straight to your Hevy profile. Built for lifters and physique athletes who care about the details.

AI BODY FAT SCANNER
Get your body-fat percentage from a single photo — no calipers, no DEXA appointment. aXis uses computer vision and your height as a reference to estimate composition, with a confidence score on every scan.

40+ BODY MEASUREMENTS
Track neck, chest, waist, hips, biceps, forearms, thighs and more — automatically estimated from your scan, so your body measurements stay current without a tape measure.

TWO-WAY HEVY SYNC
aXis is the only body scanner that syncs both ways with Hevy. It pulls your full workout history in, and posts your AI body measurements back to your Hevy profile. Your training and your physique data live in one place.

SYMMETRY LAB
Track left vs. right for biceps, thighs and forearms and close imbalances before they hold your aesthetics back. Trend graphs cover body-fat %, every circumference measurement, and your workout volume over time.

AI NUTRITION & CALORIE SCANNER
Snap a photo of your meal and AI estimates the calories and macros. See your daily calorie target and progress right on your dashboard.

AI COACH
Ask anything about your training, nutrition, and body composition. The AI Coach grounds its answers in your own Hevy workouts and aXis measurements.

PRIVACY FIRST
Your body-scan photos stay on your device and are never backed up to the cloud. You explicitly approve AI processing before any feature runs.

aXis Pro unlocks unlimited AI body scans, the AI Coach, and full analytics. Free to download and try.
