Reconstitution and draw volume.
Enter a vial's contents and your target amount. Vialtally returns the deterministic reconstitution volume and draw volume — pure unit conversion, with published test vectors behind it.

Peptide calculator and tracker for iPhone
Every number,
measured exactly.
Vialtally applies deterministic arithmetic to the values you enter — reconstitution, draw volume, unit conversion, and vial-remaining math — then logs it. It never suggests an amount or a schedule; every figure it shows comes from what you typed in.

A calculator and a tracker. Nothing else.
Vialtally reflects the numbers you give it. It never recommends one.
Vials, schedules, and history.
Log a dose, a vial change, or an injection site. Vialtally keeps a running vial-remaining total and a schedule built only from your own entries and last logged dose.
Not medical advice.
Vialtally is a calculator, log, tracker, and reminder. It does not provide medical advice or recommend an amount or schedule. Check with a healthcare professional before making medical decisions.
