Caliper is the precise, private way to track your GLP-1, peptide, and compound protocol — every dose, every level, every trend in one place. Log a dose in one tap. Watch what's active in your body build and clear on a clean levels curve. Keep an honest, fully editable record — with gentle reminders so you never lose the thread. WHY CALIPER • See what's active in your body — a curve models each compound across the week from its half-life, so you can watch it build and clear at a glance • One-tap logging — dose, time, and injection-site rotation come ready from your protocol; adjust anything, or backfill a past dose • Reminders that respect you — dose nudges and a weekly check-in, never nagging, never shame TRACK WHAT MATTERS • Doses & schedules — pens, vials, oral, and multi-ingredient blends • Weight & BMI — trends that read clearly at a glance • Side effects — log symptoms and severity over time • Progress photos — private, stored on your device, never uploaded • Injection sites — rotation history and a site heatmap • Supplies — vials, pens and tablets on hand, with expiry and use-by dates TOOLS BUILT IN • History — a full ledger, calendar, and per-compound detail • Insights — patterns and trends from your own data • Provider export — share a clean summary as a PDF • Journey Card — mark a milestone and share it, only if you want PRIVATE BY DESIGN Your data lives on your device. Progress photos never leave it. Sign in to securely back up your record and move to a new phone — nothing more, nothing sold. CALM, FAST, YOURS A precise, uncluttered interface with full Light and Dark mode. No ads. No feed. No noise. A paid subscription is required to access Caliper's tracking features. Caliper organizes and describes the data you enter. It does not provide medical advice and does not recommend a dose, schedule, or outcome. Always follow the guidance of your healthcare provider.

Caliper turns a quick front-and-side scan into body composition estimates, measurements, private shape comparisons, and progress trends—giving you a clearer view of how your body is changing than weight alone can provide. Whether your goal is to lose fat, preserve or build muscle, or improve your overall body composition, Caliper helps you see whether your progress is moving in the direction you want. FAST ENOUGH TO USE REGULARLY Complete your front-and-side scan in seconds and get your results right after you submit. No appointments. No specialized equipment. No waiting months between expensive assessments. Because Caliper is easy to use from home, you can scan regularly and follow the direction and pace of change—not just rely on an occasional snapshot. NOT A GENERIC AI PHOTO GUESS Caliper does not send your images to a general-purpose AI model and ask it to guess. It uses guided scans and purpose-built machine learning models trained with thousands of real body measurements and DEXA body-composition scans. That gives you a more rigorous and consistent way to track body composition and progress over time. SEE WHAT’S WORKING Compare scans, visualize changes in body shape, follow your trends, and see personalized projections based on your own progress. Clear guidance helps you understand what changed, what it may mean, and what to focus on next. Ask follow-up questions to explore your results, trends, and progress in more detail. PRIVATE BY DESIGN Your scan photos are used to take your measurements, then deleted. Caliper keeps your silhouette and results—not the photos themselves. This lets you compare body shape and visualize progress without keeping a gallery of revealing scan photos. Caliper is intended for general wellness and fitness purposes only. Results are estimates and are not medical measurements, diagnoses, or medical advice. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
