The complete picture of your child's health

Weight, height and head circumference against WHO percentile curves. Premature-baby corrected age built in.

Health Checks
State-specific check schedule from birth through school age, with overdue and upcoming status.

Illness Record

No account. No cloud. No surprises.
Your child's health data is some of the most sensitive 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 account or registration required
- Zero data sent to any server
- No ads — not now, not later

"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.
We don't charge for safety. Ever.
The medicine features are free — that's a commitment, not a business model. No account, no ads, no subscriptions.
