TRT and protocol tracker apps compared (2026)

Magno, My TRT App, TRT Monitor, Himcules, TRT Tracker and Health3 side by side: what each logs, lab imports, privacy, platforms and price, checked against each app's own page.

Updated 2026-10-29 · Part of the Magno guides

TL;DR. If you want injections and bloodwork in one place on an iPhone, the apps that do both are Magno and My TRT App, with TRT Monitor as the web option. Himcules and TRT Tracker are strongest at logging doses and rotating sites. Health3 reads lab reports well but doesn't log a protocol. Pick by the one thing you need most: lab PDF import, a doctor report, privacy, or price.

Written by Lucas Paraizo, who makes Magno, so read it knowing that. Every fact about another app comes from its own App Store page or website, read on 29 October 2026. Prices are UK App Store prices and change, so check the listing before you pay.

What should a protocol tracker do?

• Log each dose as you typed it, with the date, time and site.
• Keep your bloods next to your doses, so a result can be read against what you were doing in the weeks before the draw.
• Read the lab report for you. Typing 30 markers by hand is the reason most people give up and go back to a spreadsheet.
• Keep the lab's own range with each result, in the lab's own units.
• Make a clean report for your doctor.
• Tell you plainly where your data lives, and let you export or delete it.
• Never tell you what to take. A tracker is a log, not a prescriber.

Magno

• Platforms: iPhone. Not on Android or the web.
• Logs: injections (compound, dose, site and vial), blood pressure and pulse, weight, how you feel, and lab results, all on one timeline.
• Labs: reads lab PDFs, scanned PDFs and photos on the phone, with on-device OCR. Knows UK, US and Brazilian lab naming and units. You check every row before it saves.
• Doctor report: a clean PDF of doses, blood pressure and every marker. See taking your log to a GP.
• Privacy: local-first. No ads, no analytics or tracking scripts. An account and sync are optional. Export everything or delete the account in the app.
• Price: free to start. Pro is £4.99 a month (first month free) or £99 once.
• Best for: people under a clinician who want doses, bloods, blood pressure and weight in one place, with the lab report read for them.
• Not for: anyone who wants an app to suggest a dose. Magno never does.

My TRT App

• Platforms: iPhone, Android and Apple Watch, according to its site; the UK listing also covers iPad.
• Logs: doses, vials and injection sites, with a body map that suggests the next site. Weight, body fat and BMI. Blood pressure isn't mentioned.
• Labs: typed in by hand on the free tier; photo and PDF scanning with AI on Pro.
• Privacy: its site says logs stay on your phone and no account is needed to start; the App Store listing mentions sign-in and data synced to Firestore. Worth reading the privacy policy if that matters to you.
• Price: free tier with one vial and one supplement. Pro is £9.99 a month or £99.99 a year on the UK store, with a 7-day trial for new iPhone subscribers.
• Best for: people who want reminders, vial tracking and site rotation on iPhone or Android.

TRT Monitor

• Platforms: a web app that runs in the browser on a phone, tablet or computer. No App Store app.
• Logs: doses and injection sites.
• Labs: typed in, with optional AI-assisted import from an uploaded document.
• Doctor report: a shareable link for a date range that your doctor can open without an account.
• Account: needed.
• Price: one month free with no card, then £5 a month, £12 a quarter or £36 a year. Your records stay viewable if you cancel.
• Best for: people who want to use a computer as well as a phone, or who use Android.

Himcules

• Platforms: iPhone.
• Logs: doses, schedules, reminders and vial supply, with 14 injection sites and rotation.
• Labs: none. It estimates levels from your doses instead of reading bloods.
• Doctor report: a PDF, and CSV export.
• Privacy: data is stored on the device and backed up to iCloud.
• Price: free; a premium tier is announced without prices.
• Best for: a simple, free dose log with site rotation.

TRT Tracker: Injections log

• Platforms: iPhone, iPad and Mac (Apple silicon).
• Logs: injections and other routes, with a body map and site rotation. Apple Health integration.
• Labs: typed in by hand, with charts. Import isn't mentioned.
• Privacy: the developer states no data is collected; iCloud sync is available.
• Price: free with in-app purchases; full access is listed from £3.99 a week, £4.99 to £5.99 a month or £19.99 to £24.99 a year in the UK.
• Best for: dose logging across Apple devices.

Health3

• Platforms: iPhone, with iPad and Mac compatibility; its site also mentions Android.
• Logs: bloodwork only. It doesn't log doses or injections.
• Labs: PDF or photo import, typed entry, and Apple Health clinical records in the UK. Ongoing automated scanning needs Premium.
• Export: a PDF of one test, one topic or the full history.
• Price: free with in-app purchases; Premium is £5.99 a week, £8.99 a month, £57.99 a year or £149 once in the UK.
• Best for: reading and charting lab results when you don't need a protocol log.

Which one should I pick?

• Injections and bloods in one place, on iPhone: Magno or My TRT App. Magno reads the lab report on the phone and adds blood pressure; My TRT App adds reminders and Android.
• You use a computer or Android: TRT Monitor.
• You only want a free dose log with site rotation: Himcules.
• You only care about lab results: Health3.
• Privacy first: look for on-device storage and no account. Magno and Himcules both keep data on the phone; check each listing's privacy label before you start.

Is a spreadsheet good enough?

For doses alone, yes. It falls down on bloods: every marker typed by hand, units mixed between labs, and nothing that lines a result up with the weeks of doses before it. If you stay on a spreadsheet, keep one row per draw, record the time of the draw, and copy the lab's range next to each value. There's more on that in reading your first blood test.

Try Magno
