Case Study
Vidunderlig — Baby Development Tracker
The Challenge
What Needed Solving
The client needed a parenting application that tracks baby developmental leaps based on validated child development research, delivers personalised guidance content, and sends timely notifications when a new developmental phase is approaching. Content had to feel warm, expert-backed, and not alarmist — a balance that proved critical for user retention.
Our Approach
What We Built
We built a React Native application with an age-calibrated milestone tracking engine, personalized push notification sequences tied to the baby's birth date, activity logging with developmental context, and a content delivery system for expert-written guidance articles. The app design prioritised emotional warmth alongside clinical accuracy.
