As previewed earlier this month, Google today released the NotebookLM app for Android and iOS ahead of I/O 2025. This native experience starts on a homepage of your notebooks with filters at the top for Recent, Shared, Title, and Downloaded. The app features a light and dark mode based on your device’s system theme with no manual toggle. Each colorful card features the notebook name, emoji, number of sources, and date, as well as a play button for Audio Overviews. There’s background playback and offline support for the podcast-style experience (the fullscreen player has a nice glow), while you can ”Join” the AI hosts (in beta) to ask follow-up questions. You get a “Create new” button at the bottom of the list to add PDFs, websites, YouTube videos, and text. Notably, the NotebookLM app will appear in the Android and iOS share sheet to quickly add sources.  When you open a notebook, there’s a bottom bar for the list of Sources, Chat Q&A, and Studio. It’s similar to the current mobile website, with the native client letting users ditch the Progressive Web App. Out of the gate, there are phone and (straightforward) tablet interfaces. It does not really take advantage of Material 3. The NotebookLM app for Android and iOS is available for download today, with Google finally addressing the top feature request from users.
