All major GLP-1 tracking apps were iOS only until Protocol launched on Android in May 2026. Protocol is the only full-featured GLP-1 tracker on Android with dose logging, titration scheduling, injection site rotation, and the compounded vial calculator.
Tracking a GLP-1 protocol involves weekly injections on a titration schedule that changes every 4 weeks, compounded vials that vary in concentration, injection site rotation across 4–6 zones, and weight/BMI tracking to quantify progress. A GLP-1 tracker needs to handle all of this — the injection log, the calculator for compounded concentrations, the rotation map, and the titration schedule in one view.
Protocol on Android does this. It's the first and currently the only native Android GLP-1 tracking app to exist. The reconstitution calculator handles any compounded semaglutide or tirzepatide concentration. Custom Draw mode lets you lock in a target syringe draw as your dose titrates week to week. The 3D injection site map tracks rotation history across every zone. Apple Health sync writes weight and BMI data to the Health app (Android equivalent via Google Fit sync coming in Q3 2026).
