Your scale is lying to you. Smart scales measure electrical impedance, which changes based on hydration, time of day, and what you ate. That's not body fat data — that's noise. Body Fat Scanner uses AI vision to estimate your body fat percentage from photos. No electrodes. No hydration games. Just a straightforward estimate based on what your body actually looks like. HOW IT WORKS Take a photo or upload from your camera roll Enter basic measurements (age, height, weight) Get your AI-powered body fat estimate in seconds Track progress over time with visual photo history Toggle Roast My Physique mode for brutally honest AI feedback WHY PHOTOS BEAT SCALES Even DEXA scans — the supposed gold standard — have meaningful individual variance. Your bathroom scale has no idea what's happening to your body composition. Photos capture what actually changes: how you look. This app tracks that.

Train Ultra is a private AI coach for endurance athletes: runners, trail and ultramarathon racers, and cyclists. It reads your training, remembers the context, and is always available to talk through what matters next. Bring in the workouts you already record. Train Ultra turns them into a continuous coaching relationship: a useful read after every session, an honest conversation about what it means, and a plan you can carry into the next workout. START WITH WHAT MATTERS TODAY Home opens on your day: today's workout and your coach's read of it, then anything your coach needs from you. See your week at a glance and where your goal, your training, and your body stand, and open any of them for more detail. EVERY WORKOUT GETS A REAL READ Your coach looks beyond pace and distance. Evaluations consider effort, structure, recent load, recovery, active goals, planned work, and the feedback you gave after the session. Tell the coach how it felt, report pain or a concern, and that context stays with your training. TALK IT THROUGH Ask why a workout felt hard, how this week compares with last year, whether to adjust tomorrow, or what your recovery signals mean. Share a photo, a PDF, or a race file and ask what it shows. Train Ultra can reach into your actual history instead of answering from a generic profile, and its memory makes the next conversation more useful than the first. PLAN BESIDE WHAT YOU ACTUALLY DID The training Calendar keeps planned workouts, completed activities, wellness, and race days on one timeline. Build a workout yourself or talk it through with your coach. Structured run and ride workouts can be sent to supported Garmin watches or downloaded as .fit and .zwo files. When the work is done, link plan and actual so the evaluation can judge the session against its purpose. MAPS AND RACE PREPARATION (BETA) See every run and ride on a map beside its charts. Train Ultra builds a Route Library from your activities, so the routes you repeat are easy to find. Add a race course to a goal to see its climbs, aid stations, and demands, and your coach compares them with your own training so you know what to practice. ONE COACH, ALL YOUR TRAINING SIGNALS • Activities from Garmin, COROS, or Apple Health • Sleep and recovery from Garmin, Oura, or Apple Health • Goals, race courses, and weekly training summaries • Photos, documents, and race files you share with your coach • Automatic activity titles and optional evaluation posting for linked Strava activities PRIVATE BY DESIGN Your training is used to coach you. Train Ultra does not sell your data or use it to train AI models. Provider access can be disconnected, and your account can be deleted, at any time. FREE AND PRO Start with a 14-day trial of the full coach. No credit card required. Free keeps connected workouts, automatic evaluations, wellness context, activity titles, activity maps, and your Route Library with route search, imports, and comparisons.
