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, doses remaining, expiry, and runway

TOOLS BUILT IN
• Reconstitution calculator — the exact units to draw for any vial, solved once
• 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.

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.
