Vials that keep count
The strength on the label, the water you added and the day you mixed it. What is left and the use-by date update as you log.
A logbook that shows its arithmetic
Every unit, accounted for.
Vialmetry keeps the vials you mix, the units you draw and the sites you use in one private record on your phone, and shows the working behind every number so you can check it yourself.

See it in a minute
A one-minute tour, with sample data.
Captions are shown in the film. Sample data only; the app never recommends a dose.
Sites
Rotate with a map, not a memory.
Thirty sites across the front and back of a female or male figure. Each ring fills as a site rests, against the rest period you choose, and a dashed ring marks the one that has rested longest.

The schedule you already follow
Enter your plan once. Today shows what is due, and reminders can say nothing at all on the lock screen.

A summary for your clinician
A printable page and spreadsheets for any period, shared only where you send them.
ON YOUR PHONE
Private by design
No account needed, and no ads or tracking in the app. An optional private cloud copy that only moves when you say so, and a Face ID or fingerprint lock.
Nothing hidden
Three lines of arithmetic, always on screen.
Vialmetry converts the numbers you enter. It never suggests an amount, a compound or a schedule, and every formula and source is published.
Read how the math works →concentration = strength ÷ water
volume = units ÷ 100 u/mL
amount = volume × concentration
