glp1.app Peptide Tracker and Calculator

Log your peptide doses and work out reconstitution volumes on iPhone

glp1.app is a freemium iPhone app for people who need to keep an accurate record of peptide doses. It does two things well: a dose log with dates, amounts and injection sites, and a reconstitution calculator that turns a vial strength plus the amount of bacteriostatic water you added into the number of units to draw on a standard insulin syringe. That calculation is where most mistakes happen, and doing it on paper is easy to get wrong. The app is free to use with a paid tier for longer history and export. It is a tracking and arithmetic tool, not medical advice, and it is not a regulator-cleared medical device - dosing decisions stay between you and your prescriber.
