Vialmetry is a private logbook for the vials you already have. Record what is in each vial, convert your own numbers into syringe units, log each injection and rotate your sites. Your log stays on your device, works offline and needs no account. Every input and unit stays visible, so you can check the working by hand, and Vialmetry never suggests what or how much to take.

A front and back body map shows which sites have rested, optional reminders are scheduled by your phone, and you can export a printable summary for your healthcare provider. The app itself has no ads, no analytics and no tracking.

Vialmetry is for personal tracking only; it is not a medical device and does not recommend doses.
