Weight-based dose calculator for Paracetamol and Ibuprofen. Countdown timers so you know exactly when the next safe dose is. Built for the moment that matters — 2am, scared, exhausted.
"It's 2am. Your toddler has a fever. How much Panadol can you give them? And when was the last dose?"This is the moment Caru was built for.
Every parent has been there. A hot little forehead, a crying child, a cupboard of medicine — and a completely blank mind about what's safe to give, how much, and whether it's too soon since the last dose.
The old approach was a Google rabbit hole, a back-of-the-box squint in the dark, and a lot of second-guessing. Caru calculates the exact dose from your child's actual weight, then starts a countdown to when the next safe dose is.
No more guessing. No more underdosing. No more overdosing because you lost track of the time.
Weight-based dose calculation for Paracetamol and Ibuprofen — with safety timers that protect against accidental overdose.
Every dose calculated from your child's actual weight. Not a generic age bracket — because 7 kg and 12 kg are not the same child.
Not just "4 hours" — the actual safe time. "Safe at 12:11 am." The progress bar shows exactly where you are in the dosing window.
Log temperatures across the illness and track the trend over time — useful for spotting fever patterns and informing your GP.
Tracks doses today and alerts you before approaching the safe daily maximum.
Beyond medicine safety, Caru builds a complete health record — growth tracking, immunisations, milestones, and more. Offline. On your phone.
Your child's health data is some of the most sensitive data in your life. You shouldn't have to create an account and trust a startup's servers with it just to know how much Panadol to give at 2am.
Caru is fully local. Everything lives on your phone. No backend, no database in the cloud, no company that could be sold or breached and take your data with it.
Not a US app with an Australian flag bolted on. Designed from the ground up for Australian and New Zealand families.
All 8 AU states + NT + NZ. Immunisation and health checks specific to your state. NZ includes Well Child Tamariki Ora.
Australia is multicultural. Caru is available in 20 languages — because healthcare safety should work in the language you think in.
Corrected age calculation built in. Growth charts and milestones adjust automatically for premature babies.
"I built Caru because I needed it. I was standing in my son's room at 2am, phone torch on, squinting at the back of a Nurofen bottle trying to do weight-based maths in my head. There had to be something better."
Caru was created by Michael, a Melbourne-based app developer and father, under LEME Digital — responsible for some of Australia's most widely used mobile apps. After going through the same 2am medicine moment that every parent dreads, and finding nothing on the market that properly solved it for Australian families, Caru was built. Free. Local-first. No shortcuts on safety.
