Once your phone is [connected](/app/installation#first-run), mapping an app takes one click. ## 1. Pick an app With your phone plugged in, the app lists what's installed on it. Pick the one you want to map, yours or a competitor's. ## 2. Tell it what to explore Add a short brief so the AI knows where to focus, for example: > map this app, sign-up, the main thing it does, and settings Then click **Map**. You don't have to be specific, leave it blank and Roveflow explores broadly. ## 3. Watch the Atlas build Roveflow opens the app on your phone and finds its own way through it, screen by screen, the way a real user would. The **Atlas** builds live in the app as it goes, screens fill in, journeys connect up, and a short video records each flow. ## 4. Open & share the result When the run finishes you have a complete [Atlas](/concepts/the-atlas): every screen as a tile, wired into the real user journeys, with a walkthrough video per flow. Open it full-screen, click through it, or hand the shareable page to your designers to rebuild, or out-design. See how the finished map is laid out and how to read it.
