Comments on Ped(z) - Pediatric Calculator for Android

★★★★★ Abhishek Das · Oct 7, 2025
I don't usually rate apps, but I am rating this with 5 stars because it is VERY EXCELLENT AND USEFUL! Thanks a lot to the developer!
★★★★★ Romny Pascual Nóbriga Castro · Dec 24, 2021
I use this app almost every day in my residency, it is very accurate, you can compare it with the charts, and it's as good as if you do it manually, but it's faster, it has a lot of tools that will help you with your everyday work if you are a pediatrician
★★★★★ Mariana Herig · Apr 19, 2017
Amazing app!! I'd like to know if there's a possibility of using only the Fenton score for Neonates. I use it tens of times every day, and it bothers me a bit that I often forget to switch between scores! Thank you
★★★★★ Vito Cambodiawan · May 12, 2020
This app saves me in my medical rotation and ER. Everything that you could ask for pediatric data, this app has it. Furthermore, it is free!!! God bless you Mr. Developer
