Roundup

Best HRT tracker apps, honestly compared

We make one of these. If menopause HRT is the only thing you track, this page will tell you to use a different app — because that is the true answer, and a roundup that always crowns its own product is worth nothing to you.

Short version

If menopause or perimenopause HRT is the only thing you track, Shotlee is the more complete tool and it is free — we would rather point you there than oversell ours. For testosterone therapy alone, TRT Monitor has lab features we do not match. Peptide Plug is the right pick when hormone therapy sits alongside other protocols, or when reconstitution and cost arithmetic is the part that actually takes effort.

The three, and who each is actually for

Reviewed September 9, 2026 from each product's own published pages.

Shotlee — best overall for menopause HRT

The most complete dedicated HRT tracker of the group, and free. If hormone therapy is the only thing you track, start here.

  • Estrogen and progestogen across patch, gel, spray, oral, vaginal, ring, injection and implant
  • Structured symptom scales for flushes, sleep, mood and daily function
  • Bleeding-pattern tracking, which matters in perimenopause
  • Supply tracker with refill dates; labs when ordered
  • Native iOS and Android plus web

Price: Free for core tracking

Peptide Plug — best for multiple protocols

Ours. It earns its place when hormone therapy is one protocol among several, or when injectable and cost arithmetic is the hard part — not when menopause HRT is all you track.

  • Estradiol, progesterone, testosterone, hCG, GLP-1 and peptides on one timeline
  • Reconstitution, dose-split and syringe-unit math
  • Cost per dose, per month and vial run-out
  • Free Testosterone Calculator using the Vermeulen equation
  • 86-compound half-life table with published evidence levels
  • No bleeding-pattern tracking; no vaginal, ring or implant routes

Price: Free for one active cycle; Pro $4.99/mo or $49.99/yr

We make one of these apps. The recommendations above still send most single-purpose HRT users elsewhere, because that is the honest answer.

Common questions

What is the best HRT tracker app?
For menopause and perimenopause HRT specifically, Shotlee is the most complete and it is free — broader route coverage, structured symptom scales and bleeding-pattern tracking. For testosterone therapy, TRT Monitor is purpose-built with AI lab import. Peptide Plug, which we make, is best when hormone therapy is one protocol among several.
Is there a free HRT tracker?
Yes. Shotlee states its core HRT tracking is free. Peptide Plug's free tier covers one active cycle plus all public calculators. TRT Monitor offers a free first month before subscription.
Which app tracks estradiol patches, gel and injections together?
Shotlee covers the widest range of routes including vaginal products, rings and implants. Peptide Plug covers patch, gel, spray, oral and injection, and adds reconstitution and cost math for injectables.
Which tracks bleeding patterns?
Shotlee. Peptide Plug does not, which is a genuine gap worth knowing before choosing if you are perimenopausal.
Do any of them estimate hormone levels?
All three show estimated level curves. Peptide Plug publishes the underlying half-life figures with an evidence tag for each of 86 compounds, including estradiol valerate, estradiol cypionate and oral and vaginal progesterone. None of these are blood measurements.
Can one app cover both TRT and menopause HRT?
Peptide Plug covers both on one timeline, along with GLP-1 and peptides. Shotlee focuses on estrogen and progestogen; TRT Monitor focuses on testosterone therapy.
