DosePilot turns your vial numbers into exact syringe units. Enter your vial strength, water added, and prescribed dose. Get your draw in units, with every step of the math shown.
DosePilot is an educational math tool, not medical advice. It only converts the values you enter.

Calculator
Powder and pre-mixed modes cover vials and pens. The mg/mcg toggle converts your entry, never reinterprets it, so 250 mcg stays 250 mcg. Every result shows its work: concentration, draw volume, syringe units.

Beyond the math
Every calculation saved with date, vial, and units. Full history, searchable.
Gentle nudges on your schedule. Never miss a dose day.
Weight trend, dose streak, and milestone share cards.
