Your TRT log, your bloodwork and your training. Finally in one place.

Vayl keeps what you take next to 284 lab markers, every set you log, what you eat, how you sleep and how you feel. On the web terminal your markers share one timeline with the half-life curves of what you take, your calories and macros and your cardio.

Log with no signal. It syncs when you're back.
Export your records from the iPhone as CSV or JSON.
One list a day: morning, afternoon, night.
The iPhone records it. The web terminal reads it back.
It never tells you what to take.

First month free if eligible. Cancel any time in iPhone Settings.
