Euler turns a walk into a composition. Each direction you can walk leads toward a different musical style, and the paths between them are transitions. As you move, Euler blends those styles live with Magenta RealTime 2, a generative music model from Google DeepMind. Stand still and the music settles. WALKS • Around You: a walk laid out wherever you start. Walk about 80 meters in any direction and the music turns into folk guitar, a jazz trio, kalimba or strings, depending on which way you go. Circle around and they blend. MAKE YOUR OWN Tap the map to place stops around you, or switch to Draw and trace your route with a finger. Give each stop a sound from sixteen styles: folk guitar, kalimba, choir, synthwave, bluegrass and more. Then walk it, or preview it without moving. Your walks stay on your phone. Tap Share to send one as a link. Friends with Euler open it straight in the app. A link carries the walk's shape, not where you made it, unless you choose to pin it to a place. HOW IT WORKS Your position, speed and heading go to Euler's music server, which steers the model and streams the music back. GPS jitter is filtered and snapped to the walk's paths so the music doesn't flap while you stand still. Walking faster makes the styles change faster. If you lose the connection, Euler keeps playing pre-rendered loops of the same styles until you're back online. GOOD TO KNOW • Keep Euler open while you walk. The screen stays on, and the music stops when the phone locks. • Live music streams over the internet and uses mobile data. Wi-Fi or an unlimited plan is best. • The server can take up to a minute to start. Loops play in the meantime. • Watch where you're going. Euler never asks you to go anywhere in particular. Your location is used only while the app is open, only to steer the music, and is not stored. No account, no ads, no analytics.
