Best TRT Tracker Apps for Testosterone Replacement Therapy (2026)

TRT tracking has requirements that general medication apps weren't built for. You're managing injection schedules that range from twice weekly to biweekly, rotating between IM and SubQ sites, logging exact doses in milligrams, and building a record that's useful when your prescriber reviews your next set of labs. A basic pill reminder can't do this. Here are five apps that can, with an honest look at what each gets right and wrong.

Quick Reference: Top 3 TRT Tracker Picks

1. DoneDose -- Best for injection site rotation and multi-medication protocols. Visual body map tracks IM and SubQ sites separately, with color-coded resting periods.
2. Regimen -- Best for protocol-focused tracking. Manages TRT alongside ancillary medications like anastrozole and HCG with protocol-level organization.
3. TRT Tracker -- Best for simplicity. A straightforward iOS app designed specifically for testosterone injection logging without extra complexity.

Feature Comparison

Individual App Reviews

DoneDose

DoneDose handles TRT tracking with the same approach it brings to all injectable medications — the core feature is the visual body map for injection site rotation. You tap where you injected, the app records the site, and color-coded indicators show which areas are resting and which are available. For TRT specifically, this matters because you're injecting repeatedly for years or decades. Scar tissue buildup from poor rotation is a real long-term concern.

The app supports both SubQ and IM injections, which is increasingly relevant as more TRT protocols move toward subcutaneous administration. If your protocol also includes HCG, anastrozole, or other ancillary medications, DoneDose tracks everything in one place with independent schedules for each medication. Dose logging is precise — you record the actual milligrams per injection, building a clean record for your prescriber.

Honest weakness: No bloodwork integration. You can't input your testosterone, free T, estradiol, or hematocrit levels and correlate them with your injection history within the app. For most TRT patients, lab tracking happens separately — either in a spreadsheet, through your clinic's portal, or in conversation with your prescriber.

Regimen

Regimen approaches TRT from a protocol management perspective. Instead of just tracking individual injections, it lets you define your entire protocol — testosterone cypionate twice weekly, anastrozole on injection days, HCG midweek — and then tracks adherence against that structure. This protocol-first design is genuinely useful for TRT because the regimen is the thing. Your prescriber defined a specific protocol, and what you need to track is whether you're following it.

The app includes manual lab entry, which is a step beyond most competitors. You can log your testosterone levels after bloodwork and see that data alongside your injection history, though it's manual input rather than automatic integration. For a detailed feature-by-feature breakdown, our DoneDose vs Regimen comparison covers where these two apps diverge.

Honest weakness: Site rotation tracking is basic — it handles general area rotation but lacks the visual body map and site-specific history that DoneDose offers. If you're doing IM injections in the same two or three spots, Regimen won't flag the problem as clearly.

TRT Tracker

TRT Tracker does one thing and does it cleanly: track testosterone injections on iOS. The interface is minimal and TRT-specific — no medication list to scroll through, no features designed for other drug classes. You set up your testosterone protocol, log injections with the dose and site, and the app builds your history. For someone who wants the least possible friction between injecting and logging, this is a reasonable choice.

Setup is fast and the daily experience is low-friction. The app feels like it was made by someone on TRT who got tired of using generic apps that didn't fit.

Honest weakness: iOS only, and the simplicity that's an advantage for solo TRT users becomes a limitation if your regimen grows. No multi-medication support for ancillary drugs, and the site rotation features are basic. If you're on a complex protocol, you'll outgrow it.

PepTracker

PepTracker was designed for the peptide community but works for TRT tracking too, since testosterone injections share the same fundamental logging needs — dose, site, schedule. The app includes a reconstitution calculator, which isn't relevant for pre-filled testosterone cypionate but can be useful if you're also running peptides alongside TRT. Multi-medication support means your testosterone and any peptides or ancillaries can share a single tracker.

The community around PepTracker skews toward the self-optimization crowd, and the app's design reflects that with features oriented toward tracking multiple compounds simultaneously.

Honest weakness: Not TRT-specific. The interface and feature set are designed around peptide protocols, so TRT tracking can feel like a secondary use case. Site rotation tracking is present but limited compared to DoneDose.

Medisafe

Medisafe is the largest general medication tracker on the market and can technically handle TRT reminders. Its notification system is arguably the best of any medication app — persistent, customizable, and reliable across both iOS and Android. If reminder reliability is your top priority, Medisafe delivers. The app also supports caregiver sharing and has a polished interface that handles large medication lists well.

For basic TRT scheduling — remind me every Tuesday and Friday to inject — Medisafe works fine.

Honest weakness: No injection site rotation tracking at all. No distinction between SubQ and IM routes. No TRT-specific features. Medisafe treats your testosterone injection the same as a daily blood pressure pill, which means the things that matter most for long-term TRT management — rotation, precise dose logging, route tracking — are absent. It's a great pill tracker with an injection-shaped gap.

How We Evaluated

We assessed each app specifically through the lens of TRT management:

• Injection site rotation. TRT is a lifelong therapy. Proper site rotation prevents scar tissue, ensures consistent absorption, and matters more with each passing year. We weighted this feature heavily.
• SubQ and IM support. Modern TRT protocols use both injection routes. We evaluated whether each app can distinguish between them and maintain separate site rotation histories.
• Dose precision. TRT doses are measured in milligrams and often adjusted based on bloodwork. We looked for apps that log exact doses rather than just "taken/not taken."
• Protocol management. TRT rarely exists in isolation. HCG, anastrozole, and other ancillary medications are common. We evaluated multi-medication support and protocol-level tracking.
• Long-term usability. TRT is indefinite therapy. We considered whether each app builds a useful historical record and remains practical over months and years of daily use.
• Bloodwork correlation. We assessed whether injection history could be meaningfully connected to lab results, recognizing that no app in this category does this automatically.

Frequently Asked Questions

What is the best app for tracking TRT injections?

For injection site rotation and dose logging, DoneDose is the strongest option with its visual body map and support for both SubQ and IM injection tracking. Regimen is a solid alternative with protocol management features. TRT Tracker offers a simple, TRT-focused experience for iOS users.

Should I track both SubQ and IM testosterone injections differently?

Yes. SubQ and IM injections use different sites, different needle gauges, and different rotation patterns. Your tracker should distinguish between injection routes so your site rotation history is accurate for each method.

How often should I rotate TRT injection sites?

Every injection should go to a different site. For IM injections, rotate between the ventrogluteal, vastus lateralis, and deltoid muscles. For SubQ injections, rotate between areas of the abdomen, thigh, and upper arm. Never inject the same site twice in a row. A proper rotation pattern becomes second nature, but a tracker removes the guesswork — especially in the first few months.

Can I use a general medication tracker for TRT?

You can, but general trackers lack TRT-specific features like injection site rotation, SubQ vs. IM route tracking, and non-daily scheduling. Apps like Medisafe handle basic reminders well but weren't designed for the specifics of injectable hormone therapy.

Do any TRT tracker apps integrate with bloodwork results?

Most dedicated TRT tracker apps do not offer direct bloodwork integration as of 2026. Regimen includes some manual lab entry features. For full bloodwork tracking, most TRT users maintain a separate record and bring their injection log to lab review appointments.

Done Dose was built for injectable medications — and TRT is exactly the use case where that focus pays off. Visual site rotation with a body map, support for SubQ and IM protocols, precise dose logging, and room for your full protocol including ancillary medications. Your injection history becomes a record worth bringing to your next lab review. See how Done Dose handles TRT tracking.
