Product Builder · LiveLimmatBuddy
LimmatBuddy started as an idea to make swimming in Zürich safer and easier. I shaped the product, UX and technical implementation and took it from concept to production across web, iOS and Android. It combines live river conditions, safety information, maps and routing and reaches up to 400 daily users on sunny summer days. The next release is still in development.
Total usage
What the numbers mean
- Total installs
Cumulative installations through the date shown. These can include repeat installs and are not a count of unique people or current users.
Apple metric definitions- Installed audience
People with the app installed on at least one Android device used in the previous 30 days, as of the date shown. They did not necessarily open the app.
Google Play metric definitions- Active Users
People who used the app in a single day. “Up to” describes an observed daily peak, not an average. Sunny-day figures describe usage on those days.
These metrics measure different things and are not added together.

Story
Why and how I built it
The app focuses on the practical information needed before entering the water: current conditions, route context and clear preparation steps in one mobile experience.
An interactive map, route planning, alerts and warnings extend LimmatBuddy beyond river data and help people make safer, better-timed decisions for their day on the Limmat.
