TRT Tracker for Android

Protocol is the only TRT tracking app available on Android as of June 2026. Injection logging, bloodwork panel tracking, ester calculator, and injection site rotation — all on Android.

The Android TRT Tracking Gap

Before Protocol's Android launch in May 2026, TRT users on Android had no native tracking option. Every app built for testosterone protocol management — including the few that advertised TRT-specific features — was iOS only. Android TRT users tracked in spreadsheets or the Notes app, without access to built-in reconstitution math, bloodwork logging, or ester calculation.

Protocol changed this. The Android app includes the full TRT-specific feature set: injection logging with ester type, injection site rotation across bilateral IM zones (gluteal, deltoid, vastus lateralis), the TRT ester calculator (free testosterone content per labeled dose across 6 esters), bloodwork panel logging for the full TRT panel, and the PK half-life plotter for testosterone ester concentration modeling. All free. All on Android.

Is there a TRT tracking app for Android?
Protocol is the only full-featured TRT tracker available on Android as of June 2026. It logs testosterone injections (dose, ester, site), bloodwork (Total T, Free T, Estradiol, Hematocrit), includes the TRT ester calculator, and handles multi-compound tracking for TRT alongside peptides. Available free on Google Play.
Does Protocol's Android app include the ester calculator?
Yes. The TRT ester calculator is included in Protocol's Android app with full feature parity to iOS. Enter your labeled dose and ester type to get actual free testosterone content, half-life, and equivalent dosing across ester types. Covers Testosterone Cypionate, Enanthate, Propionate, Undecanoate, Sustanon blend, and oral Undecanoate.
