AFTR: GLP-1 Muscle Tracker

AFTR is the first app built specifically for people on GLP-1 medications (Ozempic®, Wegovy®, Zepbound®, Mounjaro®) — to help you keep your muscle while you lose the weight. When you lose weight on a GLP-1, a meaningful share of that loss can be muscle, not just fat. AFTR helps you protect it by making three things simple — hitting your protein, staying consistent with resistance training, and tracking how it's going — then showing whether you're on track with your daily Muscle Retention Score. PROTEIN, MADE EFFORTLESS • Snap a photo of your meal and AFTR estimates the protein for you • One-tap quick-adds for the high-protein foods you eat on repeat • A protein-first daily target tuned to your goals — because on a GLP-1, the hard part is eating enough YOUR MUSCLE RETENTION SCORE • A single 0–100 indicator of how well you're protecting muscle, from your protein, training, and rate of loss • See at a glance whether you're on track TRACK THE WHOLE JOURNEY • Log your weight and watch the trend over time • Check in on your "food noise" and watch it quiet down week over week • Note side effects like nausea and fatigue and spot patterns • Backfill any past day so your history stays complete STAY CONSISTENT WITH TRAINING • Simple resistance-training check-ins that help preserve muscle • A weekly view that keeps you honest SHARE YOUR WEEKLY WIN • Every week, AFTR builds a shareable card of your progress AFTR+ Your Muscle Retention Score, your weekly move, and your shareable Weekly Win are always free.
