The story

A question I hear at the counter every day

The problem

"How many mL do I give?"

Kids' doses depend on weight, and bottles come in different strengths. Parents ask at the pharmacy or in a group chat, then two hours later forget the time or mix up two medicines.

The fix

A pharmacist in your pocket

ZA Dose calculates the dose in mL for the exact bottle, checks the child's health file before showing it, and reminds you on time even when the phone is silent.

In a few minutes
