Looking for an app to track your TRT? Here's an honest comparison of what's available in 2026.
If you're on testosterone replacement therapy, you've probably tried tracking your injections in a notes app or spreadsheet. It works for a while, then falls apart. You miss entries. You can't see patterns. You show up to your blood test with no useful data.
TRT-specific apps solve this. But which one should you use?
I've tested the main options and compared them on what actually matters: logging doses, tracking symptoms, recording bloodwork, and seeing trends over time.
Quick comparison
| App | Platform | Price | Best for |
|---|---|---|---|
| TRT Monitor | Web (any device) | Free | Doctor-sharing, blood test tracking |
| OptiPin | iOS only | Free + IAP | Peptides, calculators, inventory |
| TRT Plus | Android only | $12.99 | Enhanced athletes, cycle planning |
| TRT Tracker | iOS only | Free + IAP | Simple injection logging |
TRT Monitor (web)
Price: Free, no in-app purchases
Platform: Web app, works on any device
Best for: Tracking injections, symptoms, and bloodwork in one place
TRT Monitor is a web-based tracker built specifically for men on TRT. You log your doses, rate daily symptoms (energy, mood, libido, sleep), and record blood test results with reference ranges.
The standout feature is shareable reports. You can generate a PDF or link to share with your doctor, showing your injection history, symptom trends, and lab results. No more scribbling notes before an appointment.
What it does well:
- Blood test logging with visual trends
- Symptom correlation (see how you feel vs. when you inject)
- Shareable reports for clinic visits
- Saturation curve calculator
- Works in any browser, no app store needed
What it lacks:
- No native iOS/Android app
- No peptide support
- No injection site rotation tracking (yet)
Who should use it: Anyone who wants a free, private tracker with strong blood test features and the ability to share data with their doctor.
OptiPin (iOS)
Price: Free with in-app purchases
Platform: iOS only
Best for: Peptide users, people who want calculators and inventory tracking
OptiPin is the most feature-rich TRT app on the App Store. It tracks TRT, peptides, and GLP-1 medications with a visual injection site map, dosage calculators, and inventory management.
The app stores everything on your device (no account needed), which appeals to privacy-conscious users. It also integrates with Apple Health.
What it does well:
- Injection site rotation with body map
- Peptide dose calculators
- Inventory tracking with low-stock alerts
- Estimated hormone concentration curves
- 100+ medication database
What it lacks:
- iOS only (no Android or web)
- No doctor-sharing features
- In-app purchases for full access
- Newer app with smaller user base
Who should use it: iOS users who also track peptides or GLP-1 medications and want calculators built in.
TRT Plus (Android)
Price: $12.99 (one-time)
Platform: Android only
Best for: Enhanced athletes running cycles
TRT Plus targets users who go beyond standard TRT. The app includes cycle planning, compound stacking, and features aimed at bodybuilders and "enhanced athletes."
It's a paid app with no free tier. If you're on straightforward TRT from a clinic, this is more than you need.
What it does well:
- Cycle planning and stacking
- Designed for multiple compounds
- One-time purchase, no subscriptions
What it lacks:
- Android only
- No free version to try
- Overkill for basic TRT users
- Smaller development team
Who should use it: Android users running more complex protocols who want dedicated cycle planning.
TRT Tracker: Injections log (iOS)
Price: Free with in-app purchases
Platform: iOS only
Best for: People who just want simple injection logging
TRT Tracker is a straightforward iOS app for logging doses. It does one thing and does it simply. No bells and whistles.
What it does well:
- Clean, simple interface
- Quick dose logging
- Basic reminders
What it lacks:
- Limited symptom tracking
- No blood test features
- No doctor-sharing
- iOS only
Who should use it: iOS users who want the simplest possible injection log.
Spreadsheets (DIY)
Some people still track TRT in Google Sheets or Excel. It works, technically.
Pros:
- Free
- Fully customisable
- Works offline
Cons:
- No reminders
- Charts require manual setup
- Hard to share with doctors
- Easy to forget entries
- No mobile-friendly data entry
If you've tried a spreadsheet and kept up with it for 6+ months, you have more discipline than most. For everyone else, a dedicated app saves time.
Which TRT tracker should you use?
Choose TRT Monitor if:
- You want something free with no catches
- You track blood tests and want to see trends
- You want to share reports with your doctor
- You use both phone and desktop
Choose OptiPin if:
- You have an iPhone
- You also use peptides or GLP-1 meds
- You want calculators and inventory tracking
- Privacy (no account) matters to you
Choose TRT Plus if:
- You're on Android
- You run complex cycles beyond basic TRT
- You're willing to pay $12.99
Choose a simple app (TRT Tracker) if:
- You only need injection logging
- You don't care about symptoms or bloodwork
- You prefer minimal apps
What about Apple Health and Google Fit?
Generic health apps can log medications, but they're not built for TRT. You can't track injection sites, correlate symptoms with doses, or visualise hormone levels against reference ranges.
Use a TRT-specific tracker for your therapy, then sync to Apple Health if you want an overall health picture.
Final thoughts
The best TRT tracker is the one you'll actually use. Fancy features mean nothing if you stop logging after two weeks.
If you want a free, no-nonsense option that works anywhere and helps you share data with your doctor, TRT Monitor is worth trying.
If you're deep into peptides and want calculators, OptiPin is solid on iOS.
If you're running cycles that go beyond TRT, TRT Plus exists for that.
Pick one. Use it consistently. Your future self (and your doctor) will thank you.
