The 5 Best TRT Tracker Apps in 2026
Last verified: July 8, 2026
Why a TRT tracker matters
Testosterone replacement therapy is not a medication you take once and forget. Depending on protocol, you inject once or twice a week, monitor labs like total testosterone, free testosterone, hematocrit, estradiol (E2) and SHBG, rotate injection sites between thigh, deltoid, and ventrogluteal -- and adjust dose until your provider is satisfied.
A calendar reminder tells you when to pin. It does not tell you which site you used last week, how your testosterone level fluctuates between injections, or whether your Wednesday fatigue lines up with the trough before your next dose.
How we evaluated
We compared every TRT tracker we could find against its own App Store or Google Play listing, official site, and privacy policy. The following criteria decide whether a tracking app is actually useful:
Multi-compound depth. Anyone tracking seriously ends up running more than one compound. Can the app handle multiple compounds at once?
Pattern detection. Does the app surface relationships between dose, sleep, energy, and labs over time? Or is it just a logbook?
Daily check-in depth. How many markers can you capture per check-in? Photos, injection sites, custom markers?
Calculator coverage. Are reconstitution, intranasal, and oil-based dosing calculators built in?
Health data integration. Does the app sync with Apple Health or Google Health Connect?
Design and UX. A tracker is opened daily. Bad design becomes obvious after a week.
Freemium scope. How far do you get without paying? Real free tier or a demo?
Privacy. No data sales, full export, account deletion. Minimum bar for any health tracker.
The 5 best TRT & testosterone tracker apps in 2026
We compared every TRT tracker we could find against its own App Store or Google Play listing, official site, and privacy policy. From specialized injection trackers to multi-compound platforms to apps with built-in pharmacokinetic modeling: here is what each app actually does. All ratings reflect the global App Store on the last verification date.

1. Regimen
Platforms: iOS + Android 路 Price: Free + $4.99/mo 路 Rating: 4.9 stars (230+ reviews, global)
Regimen focuses on what is actually happening in your body, not just what published pharmacokinetics say should be happening. The half-life visualization is ester-specific for Cypionate, Enanthate, and Propionate, so you can see where you land in the trough and why certain days feel different.
Lab tracking covers the markers that actually matter on TRT: Total testosterone, Free testosterone, E2, SHBG and Hematocrit. The Signals engine correlates dose changes against real outcomes -- energy, sleep, body composition, lab trends -- over weeks and months.
Apple Health and Google Health Connect sync on both platforms. When your protocol grows (HCG, anastrozole, peptides), the Premium tier covers it with a library of 200+ compounds and brands.
What it does best: Ester-specific half-life visualization. Lab tracking for Total T, Free T, E2, SHBG, HCT. Signals engine that correlates dose against real outcomes.
Where it falls short: Newer app with a smaller review base than pure logbook tools.
Best for: TRT patients who want to know what is actually happening in their body, not just what should be happening on paper.
2. MyTRT
Platforms: iOS + Android 路 Price: Free tier + $9.99/mo 路 Source: App Store
MyTRT is a TRT-focused companion for iOS and Android. Log injections, lab values, and protocol changes across 40+ biomarkers (total T, free T, E2, SHBG, HCT). It models testosterone against your protocol, correlates lab movements against dose changes, and handles multi-compound protocols including HCG and anastrozole.
What it does best: 40+ biomarkers. Level modeling. Correlation. HCG and anastrozole support. iOS and Android.
Where it falls short: Very new (a handful of App Store ratings so far). Lab scanning runs through the cloud. $9.99/mo is above the category norm.
Best for: TRT users who want to track labs and injection history for free.
3. OptiPin
Platforms: iOS 路 Price: Freemium 路 Source: App Store 路 optipin.app
OptiPin combines TRT and peptide tracking in one iOS app. Bloodwork-calibrated level modeling for T, DHT, and E2 sits on top of a 100+ site rotation map. A sensible choice for users running a testosterone protocol and a peptide stack at the same time on iPhone.
What it does best: TRT + peptides on iOS. Bloodwork-calibrated T/DHT/E2 modeling. Detailed site rotation map. Local-first privacy stance.
Where it falls short: iOS only (no Android or web). Doctor export is CSV, not a formatted PDF report. Automatic site-rotation suggestions not built yet.
Best for: iOS users who want to track TRT and peptides together.
4. TRT Tracker: Injections log
Platforms: iOS 路 Price: Free + in-app purchases 路 Rating: 4.4 stars (22 reviews, global) 路 Source: App Store
TRT Tracker is a simple iOS tool for logging injections, doses, and symptoms -- without unnecessary complexity.
What it does best: Fast injection log. Simple symptom capture.
Where it falls short: No lab analysis. No half-life visualization. iOS only.
Best for: TRT users who want a straightforward injection log.
5. TRT Monitor
Platforms: Web 路 Price: Free trial, from 拢3/mo 路 Source: official site
TRT Monitor is a web-based option -- no app download required. Strengths: clean lab tracking and exportable PDF reports for your provider.
What it does best: Provider export, lab data overview (Total T, Free T, estradiol, SHBG), device-independent. Correlation insights across the timeline.
Where it falls short: No half-life visualization. No Apple Health integration.
Best for: TRT patients who need structured reports for their provider.
