7 Best TRT Tracker Apps in 2026 — Tested & Compared

The 7 Best TRT Tracker Apps in 2026

You're here because you want to find the right app. We tested every TRT tracking app we could find. Here's what each one actually does well, where it falls short, and who it's best for.

1. Regimen

Regimen was built for people running multi-compound protocols. TRT + HCG + AI + peptides + GLP-1. It's the only app on this list that handles a full protocol in one place, with a library of 600+ compounds to pull from.

If you're just tracking testosterone, the app is free with full features (one compound included). The premium tier unlocks unlimited compounds for stacking.

The in-app tools include a reconstitution calculator, a half-life visualizer with PK curves, injection site tracking with rotation suggestions, and correlation charts that overlay dose changes against health metrics from Apple Health or Health Connect. You also get qualitative tracking (sleep quality, energy, cravings), blood pressure logging, and a visual photo tracker.

What it does best: Handles the full stack. TRT + ancillaries + peptides + GLP-1, all in one app with PK curves and health correlation. If your protocol grows (and most do), you don't need to switch apps.

Where it falls short: Smaller review base than some competitors. No home screen widgets yet.

Best for: Anyone running more than just testosterone. If your protocol includes HCG, anastrozole, peptides, or GLP-1 compounds, this is the only app that tracks everything without workarounds.

2. OptiPin

OptiPin supports 100+ medications and offers level projections for testosterone, DHT, and GLP-1 compounds. It's privacy-focused (no accounts required) and supports custom protocols.

The 75 reviews make it the most-reviewed dedicated tracker on this list, and the 4.47 rating suggests most users are happy. The medication database is broad, covering more compounds than most competitors.

What it does best: Large medication database (100+), level projections for multiple hormones, privacy-first approach.

Where it falls short: iOS only. Requires iOS 18.1 or later, which cuts out anyone on older devices. The user experience is clunky and unintuitive, with a steep learning curve to figure out basic tasks. The lifetime pricing ($74.99-99.99) is steep for a tracker app.

Best for: iOS users who want broad medication support with level estimates and don't mind paying for a polished experience.

3. TRT Plus

TRT Plus goes deeper on pharmacokinetics than any other app here. It models ester release curves, supports 80+ compounds in advanced mode, and even offers bloodwork OCR scanning that can pull values from lab result photos.

The one-time purchase model is refreshing in a world of subscriptions. Pay once, use forever.

The built-in knowledge base and lab ordering affiliate (partnered with a lab service) add utility, though the affiliate relationship is worth noting since it means the app has a financial incentive to push lab ordering.

What it does best: Deepest pharmacokinetic modeling available. Bloodwork integration via OCR. One-time purchase.

Where it falls short: Multiple reviews mention the UI is "very unintuitive." The learning curve is steep. The app tries to do a lot, and the interface struggles to keep it all accessible. Android ratings (3.6) suggest platform-specific issues.

Best for: Data-driven users who want detailed pharmacokinetic modeling and don't mind a steeper learning curve.

4. Himcules

Himcules is a clean, focused, completely free TRT tracker built by a solo developer. If you only inject testosterone and want the simplest possible experience, this is hard to beat.

The scheduling is smart. Set your protocol (E3.5D, EOD, weekly, whatever) and it handles the calendar math. It tracks six injection sites with rotation reminders, and the ester release plotting (pharmacokinetic curves) is a genuinely useful touch. You can see estimated testosterone levels between injections, which helps visualize why E3.5D protocols feel smoother than weekly ones.

Home screen and lock screen widgets are a nice daily convenience that no other app on this list offers. Privacy is handled well too: no cloud, no accounts, everything stays on your device.

What it does best: Clean design, great widgets, PK curves, and it's completely free. Zero catch.

Where it falls short: TRT only. Can't track HCG, anastrozole, peptides, or anything else. iOS only. Only 3 reviews so far.

Best for: Guys on a simple testosterone-only protocol who want a polished, free, private tracker on iOS.

5. TRT Monitor

TRT Monitor takes a different approach: it's a web app, not a native mobile app. Open it in any browser on any device. No downloads, no app store, no platform restrictions.

The standout feature is shareable doctor reports. You can generate a formatted summary of your protocol, doses, and symptom trends, then share it directly with your provider. AI-powered blood test import parses your lab results and adds them to your timeline.

What it does best: Free, works on any device, shareable reports for doctor visits.

Where it falls short: No native app means no push notifications for dose reminders, no health platform integration (Apple Health, Health Connect), and generally less polish than native apps. The browser-based approach trades convenience for accessibility.

Best for: Anyone who wants a free, platform-agnostic tracker with an emphasis on provider communication.

6. TRT Tracker: Injections Log

TRT Tracker offers a body map for injection sites, biomarker tracking, and symptom correlation tools. It's TRT-specific, which means the interface is tailored to hormone therapy rather than being a general medication tracker.

What it does best: TRT-specific biomarker tracking and a visual body map for injection site rotation.

Where it falls short: Several reviews mention performance issues, including phone overheating during use and notifications that don't fire reliably. iOS only. Multi-compound support (HCG, AI) is unclear from the listing.

Best for: iOS users who want TRT-specific biomarker tracking and visual injection site mapping, assuming the performance issues get resolved.

7. TRT Pro

TRT Pro is a calculator and optimizer that models your testosterone levels based on baseline labs and your protocol. Input your pre-TRT bloodwork, your current dose and frequency, and it projects where your levels should land.

What it does best: Pharmacokinetic modeling from baseline lab values. Gives you a projected outcome before changing your protocol.

Where it falls short: The Android version hasn't been updated since August 2023, which is a red flag for ongoing support. At $19.99-24.99 for limited features and very few reviews, it's the most expensive option per feature on this list. The app appears to be in minimal maintenance mode.

Best for: Users who specifically want PK modeling from baseline labs. But given the lack of updates, proceed with caution.

How to Pick the Right App for Your Protocol

Your protocol determines your app. Here's the straightforward breakdown.

The honest answer is that there's no single "best" app. There's the best app for your specific situation. A guy on TRT-only has different needs than someone running testosterone, HCG, anastrozole, BPC-157, and semaglutide. The right tool is the one that matches your protocol today and can grow with it tomorrow.

What TRT Users Actually Need From a Tracker — Insights From Regimen Data

TRT protocols vary more than most people realize, and Regimen's data reflects that diversity. Some users track testosterone and nothing else. Others pair TRT with hCG for fertility preservation, or add an AI for estrogen management. And a growing number are expanding into other categories — peptides for recovery, or GLP-1 medications for weight management alongside their TRT. The point is that a good TRT tracker needs to work for all of these scenarios, from the simplest single-compound protocol to complex multi-compound stacks. Whatever your protocol looks like, the tracker should match it — not force you into someone else's setup.

Among Regimen users, 42% self-identify as beginners on their first protocol. These users need an app that is simple enough to set up on day one but powerful enough to grow with them if their protocol evolves. The most commonly reported challenges — managing compound schedules (52%) and timing doses correctly (43%) — are universal pain points whether you are tracking one compound or five. Your doctor prescribes the protocol. Your tracker should help you follow it consistently.

The way TRT is dosed varies widely. Regimen supports every common schedule: daily subcutaneous microdosing, specific-day protocols (like Monday/Wednesday/Friday), traditional weekly injections, twice-weekly, and custom intervals. No single dosing pattern dominates among our users, which is exactly why flexibility matters. Whatever frequency your provider has prescribed, the tracker should support it without workarounds.

Regimen handles all of this natively — whether you are tracking testosterone alone or alongside other compounds, with flexible scheduling and a setup flow designed so that a first-time TRT user can be fully configured in minutes.
