What Health Coordinators Are Saying
Trusted by lecturers and students across Sri Lankan universities
"Finally a BMI tool built for school use — the student ID field and one-click PDF report save so much time during our annual health screenings."
"I use this for sports clearance checks every term. The colour-coded gauge makes it easy to explain results to students and parents at a glance."
