About Mewni

Mewni is a transit app built for San Francisco riders who actually need to get somewhere. It shows near-live vehicle positions for every Muni route, real-time arrival predictions at Muni stops and BART stations system-wide, and lets you build Journeys — named groups of route and stop combinations, so you can check several options at once instead of juggling tabs.

Why a cat?

Because staring at a loading spinner while you wait for a bus is no fun. Every vehicle on the map is a small pixel-art cat, walking its route in real time. It doesn't get in the way of the navigation — it's just a little more delightful than a plain dot.

The real cats

The app's cats are drawn, but they're modeled after real ones.
