"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.
The medicine features are free — that's a commitment, not a business model. No account, no ads, no subscriptions.
