GLP-1 management is more than a number on the scale
For users on semaglutide or tirzepatide, progress involves dose escalation schedules, side effect patterns, injection site rotation, and metabolic markers. A dedicated tracker keeps all of that visible in one place rather than scattered across notes and spreadsheets.
Dose escalation requires a structured log
GLP-1 protocols typically involve weekly dose increases over several months. Tracking the current dose, the next scheduled change, and how the body responded at each level helps users and their care teams make informed decisions at every step.
Side effect patterns are worth surfacing
Nausea, fatigue, and GI symptoms often cluster around injection timing or dose changes. Structured logging over time makes it easier to identify triggers, adjust timing, and present clear data at a clinical visit without relying on memory.
Where PenDose fits
PenDose is built specifically for GLP-1 users who want a focused, private tracking tool rather than a general wellness or diet app. Dose scheduling, site rotation, HealthKit-linked metabolic trends, and physician-ready summaries are the core of the product.
