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. FEATURES AI body fat estimation from photos Progress tracking with visual history Roast My Physique mode: choose clinical or roast-style feedback Private and secure — your photos, your data 3 free scans to try it SUBSCRIPTION Try it free with 3 scans.

Your ADHD brain runs hot — moods swing, rejection stings, focus comes and goes. Lull helps you see WHY in seconds a day, without your feelings ever leaving your phone. HOW IT WORKS • Check in with one tap — pick a mood, then tap what shaped your day: slept badly, took meds, rejection stung, overwhelmed, couldn't focus, hyperfocus, moved your body, saw people. • Lull finds the patterns for you: "on the days you slept badly, your mood runs 2 points lower — sleep is your biggest lever." • See the shape of your week, your triggers, and what actually lifts you. BUILT FOR ADHD BRAINS • A two-minute habit, not another chore. • The insight IS the reward — the dopamine of finally seeing your own patterns. • No lectures, no coaching upsell. RADICALLY PRIVATE • 100% on-device. Your entries never leave your phone. No account, no cloud, no ads, no trackers in your journal. HONEST PRICING • Journaling and mood tracking are included for everyone, always. Lull+ unlocks your deeper patterns, with a 7-day trial and no fake discounts — cancel anytime in one tap. Lull is a private self-understanding tool — not medical care, diagnosis, or treatment.
