The NotebookLM app is now the Gemini Notebook mobile app, and it lets you ask questions about your sources, listen to Audio Overviews offline, review with flashcards and quizzes, and view infographics and slide decks on your phone. As of October 2026 it runs on Android 10 and up, with an iPhone and iPad version too, but Google calls it an early version with limited features compared with the web.
The catch: it's rolling out, and it's a lighter version
Two things trip people up. First, Google says the app is rolling out gradually, so it may not be available in your country, territory or language yet. If you can't find it in your store, that's the likely reason rather than anything you've done.
Second, it isn't the full product. Google's own tip is to use the desktop version for the full Gemini Notebook experience. Here's what the help page lists as missing or limited in the app, as of October 2026:
- Sources are limited to PDF, website, YouTube, audio and copied text. Google says more input types will come over time.
- Chat configurations and chat analytics aren't supported.
- You can't generate notes, mind maps, reports or data tables yet.
- The featured notebooks tab isn't in the app, though featured notebooks opened from a link show up on your home page.
- Audio Overviews download for offline listening inside the app only, not as a file on your phone.
- Light and dark mode follow your device settings.
- Syncing between devices can be delayed. Google's fix is to quit the app and open it again.
If you rely on mind maps or reports, keep doing those on the web. My guide to the Studio tools on the web covers the full set.

The share sheet is the best reason to install it
This is the feature I'd use most. While you're reading a website, a PDF or watching a YouTube video on your phone, tap the share icon and pick Gemini Notebook. It goes straight into an existing notebook as a new source. That turns the app into a capture tool: you collect on the go and do the heavier work later.
You can also search the web from the prompt box on the home screen or inside a notebook. The app shows the most relevant results with a short note on how each one relates to your query, and you pick which ones to import.
Audio Overviews on the go
Audio Overviews are where the mobile app makes the most sense. Open the Studio panel, tap the pencil icon next to Audio Overviews, and you can choose the language, change the length, pick which sources to include and add a prompt. While it plays you can skip, pause and change speed, and it keeps playing when you switch apps or turn the screen off.
Tap Download and it appears in the Downloaded section on the main page of the app, or swipe left on an Audio Overview in Studio to download or delete it. Just remember the download lives inside the app. You can't save it as an audio file to share elsewhere. There's also an Interactive Mode, in beta and English only, where you can join the conversation with the AI hosts.
Flashcards, infographics and slide decks
Flashcards and quizzes are built for revising on the move. You set the language, the number of cards and the difficulty, then mark each card as Got it or Missed it, and retake either the whole deck or just the ones you missed. Infographics can be saved to your phone as a PNG, and you can change the orientation, sources and language.
Slide decks come with a quota catch. You can revise a deck by adding instructions to individual slides, then generating a new deck. Google's tip is to batch your revisions, because there are quota limits on how many slide decks you can revise. Adding or removing slides isn't supported during a revision yet. For the wider plan and usage limits, see whether NotebookLM is free, which goes through what each tier allows.

Getting started on your phone
- Search for Gemini Notebook in the Play Store or App Store and install the official app.
- Tap Create New, or open an existing notebook from Recent, Shared, Title or Downloaded.
- Add sources as a PDF, website, YouTube link, audio file or copied text, or use the share icon from another app.
- Open the Chat panel to see a summary of your sources and ask questions about them.
- Open the Studio panel to make Audio Overviews, flashcards, quizzes, infographics or slide decks. Generating can take a couple of minutes.
Google also reminds you that chat answers and everything Studio makes are AI-generated, so they can contain mistakes or audio glitches. Check anything important against the original source.
My verdict
I'd install it if you already use Gemini Notebook on your laptop and want to listen to Audio Overviews on a walk, revise with flashcards or grab articles and videos into a notebook as you find them. It's a good companion. I'd skip it as your only way in, because the missing mind maps, reports and notes are the parts most people build their notebooks around. Set up the notebook on the web, then let the app carry it around with you.
