Physician-designed for parents
Tylenol or ibuprofen — by your child's weight. Safe every time.
Two children at the same age can weigh 30 pounds different. The label doesn't know that. Your pharmacy's printout doesn't know that. But your child's body does. Concentrated infant drops were removed from the market after thousands of parents accidentally overdosed. That's the real stakes.
Enter your child's info, pick your medication, and get a precise weight-based dose in seconds.
Review every input, then log every dose — For the whole episode.
Perfect Dose uses the same weight-based methodology that pediatric emergency physicians use — not the age-based shortcut that leads to confusion. It takes 15 seconds. It removes the guesswork entirely.
Every feature designed for real parents in real situations — not clinical workflows.
Enter weight, get the right dose. Simple and fast — no profile setup required, no accounts, no clutter.
Covers every formulation found in every US pharmacy — so you always know exactly how much to give, whatever you have on hand.
Every recommendation reflects real clinical standards — not a marketing approximation. Developed by a board-certified emergency physician and parent.
Clean, focused interface when you need it most — at 2am with a feverish child. Nothing gets between you and the answer.
Use it straight from your browser. No downloads, no updates, no permissions. Just open the link and go.
Weight-based dosing adjusts with growth — so the dose stays accurate, whether your child weighs 15 lbs or 45 lbs.
"Perfect Dose was born between midnight fevers and middle-of-the-night pharmacy runs. As an emergency physician and father of three, I saw firsthand how hard it is for even the most attentive parents to get medication dosing right. Labels are confusing. Dosing spoons get lost. Every child is different."
