A TRT injection log that takes two taps.
Any schedule, a suggested injection site, a vial supply countdown, and a one-page PDF for your next visit. No account. Nothing leaves your phone.
Any schedule you actually use
Pick any days of the week and up to six times a day, with one reminder per slot. Reminders can say only that a dose is due, and you can log or snooze from the notification.
Log an injection in 2 taps
Tap Log shot and the dose is prefilled from last time. Change it, pick a different site, or log a past day whenever you need to.
Injection site log
Track which sites you used and when. VialBook suggests the one used least recently so you can rotate. It is a suggestion, never a prescription.
Know when the vial is running low
Count doses left per medicine and get a quiet heads up before it runs out, so a refill never catches you off guard.
Take it to your appointment
Make a one-page PDF of what you logged and bring it to your visit. You choose which medicines are on it. It only shows your own entries.
VialBook is a tracking tool, not medical advice. It never suggests a dose. Talk to your doctor about your treatment.
Does VialBook work for TRT?
Yes. It tracks any medicine you take on a schedule, including TRT vials and pens, with any dose in mg, mcg, or syringe units.
Does it tell me what dose to take?
No. VialBook never suggests a dose or gives medical advice. It records what you tell it.
Can I keep it discreet?
Yes. Hide names replaces the medicine name with a neutral label in the app, on reminders, and on the Lock Screen.
Is my data uploaded anywhere?
No. There is no account and no server. Your log lives on your phone, and you can back it up to a file you keep.
