Chapters: Photo Weight Journal

Your weight journey is more than numbers on a scale — it's a story with chapters. Built by a founder who lost 100 lbs on tirzepatide, Chapters is the photo-first weight journal designed for the GLP-1 era. Whether you're on Ozempic, Zepbound, Mounjaro, Wegovy, or tapering off — Chapters turns your weigh-ins into a visual narrative you actually want to revisit. KEY FEATURES • GLP-1 Mode A journey mode built for people on GLP-1 medications. Log your weekly dose, track side effects (nausea, food noise, fatigue, sulfur burps, more), and see your story alongside your shots. • Dose Tracker Record every injection — drug, dose, date, and notes. Shot days pin to your timeline. A calendar overlay shows your full dose history at a glance. • Taper Companion Planning to come off GLP-1? Set your taper schedule, log daily hunger and weight stability, and watch the "Day X off GLP-1" counter on your home screen and widget. • Plateau Detector Fourteen days with no movement? A soft, medical-claim-free suggestion nudges you to talk to your provider. No nagging, no shame. • Muscle Preservation Alert Losing too fast can mean losing muscle. Chapters flags rapid loss and reminds you to prioritize protein and resistance training. • Photo Timeline Every weigh-in connects to photos from that day. Scroll back and see what life actually looked like — not just what the scale said. • Photo Memories Chapters suggests photos from your library that match your weigh-in dates. No manual searching. • Interactive Charts Pinch to zoom, drag to scroll, tap any point for details. See 7-day rolling averages, weekly trends, and projected weights based on your current pace. • Apple Health Integration Read weight, heart rate, and body composition from Health. Your Health data stays in Health — we never write back. • Import From Anywhere Apple Health, MyFitnessPal, Happy Scale, Fitbit, Withings, Garmin, CSV, JSON. Bring your history with you. • Home & Lock Screen Widgets Latest weight, weekly progress, and a dedicated "Day X since last shot" widget for tapering users. • Share Cards Generate beautiful, branding-optional share cards for your progress milestones. Wellness, journal, and GLP-1 themes included. • Reflections & Tags Add notes to any chapter. Capture how you felt, what you ate, or what you learned. Pre-built tag categories for mood, meals, training, and GLP-1 symptoms. BUILT FOR PRIVACY Chapters is designed with privacy as a core principle: • All data stays on your device • No accounts, no tracking, no analytics SDKs • No crash reporting SDKs, no third-party frameworks • Photos are referenced, never copied • We literally cannot access your data MEDICAL DISCLAIMER Chapters is a journaling and tracking tool only — it does not provide medical advice, diagnosis, or treatment.
