TRT Tracker: Shots & Labs

TRTLog keeps the record for prescribed testosterone replacement: when your next injection is due, where you logged the last one, the dose you entered, and the lab results your clinic orders, charted against the ranges printed on your own reports. It works offline and needs no account.

WHAT IT DOES

Injection schedule
A countdown to your next injection, with Log injection right under it. Set the schedule your prescriber gave you: every few days, or on chosen weekdays such as Monday and Thursday. The countdown runs from the injection you actually logged.

Injection sites
A map of the glutes, outer thighs and deltoids, left and right, plus the abdomen on either side. Each site shows the days since you last logged it, and the site logged longest ago is highlighted for reference. Amber marks a site logged inside the window you set. Nothing is blocked, and sites you do not use can be turned off.

Logging an injection
The form fills in the least recently logged site and your current dose. Check both, change either, pick intramuscular or subcutaneous, and save. If you enter the concentration from your vial, TRTLog calculates the volume in mL from the dose and concentration you entered, and shows the calculation.

Dose history
Each dose change your prescriber makes, with the date it started. The app never changes a dose on its own.

Lab results
Type in each blood test: total and free testosterone, SHBG, estradiol, hematocrit, hemoglobin, PSA, LH, FSH, lipids, liver enzymes, or any other marker by name. Enter the reference range from your report, and note how many hours after an injection the blood was drawn. Each marker gets a chart over time with your range as a band and your dose changes marked.

Units
Testosterone in ng/dL or nmol/L, estradiol in pg/mL or pmol/L. Values are kept as you typed them. A chart shows another unit only when you choose it, and prints the conversion it used.

Symptom diary
Rate energy, mood, libido, sleep, acne and water retention from 0 to 4, day by day, and see each one over twelve weeks beside your dose changes.

Supply
Vials on hand in mL, with a refill reminder based on the vial amount and schedule you record.

Summary for your doctor
A PDF of the last 3, 6 or 12 months: injections with site and dose, dose changes, lab results with the ranges you entered, symptom averages and other medications.

Reminders
Injection day, the evening before a booked blood draw, and refill. Reminders say only "Scheduled reminder" and never name a medication.

Other medications
Anything else your prescriber added, recorded as written with its dose and schedule.

Backup and restore
One file with every record, to keep or move to another phone. Restoring adds what is missing and removes nothing.

WHAT YOU GET

The standard plan covers the schedule, the site map, logging, injection history, dose history, reminders, supply, backup and up to three lab panels. Pro adds more lab panels, new symptom diary entries and the doctor summary PDF. Anything you have already entered stays readable on every plan. There are no ads.

YOUR DATA

TRTLog stores your records on your phone and does not upload them to any server. There is no account and no sign-in. You can export a PDF or a backup file yourself. Crash reports and usage statistics are sent, and neither carries your health records.

WHAT IT IS NOT

TRTLog records what you enter. It does not suggest a dose, a schedule or a change, it does not interpret lab results, and it is not intended to diagnose, treat, cure or prevent any condition. Follow your prescriber.

The app is in 10 languages. The doctor summary is in English.
