Claude runs on more than the website. There are mobile apps for iOS and Android, and a desktop app for Mac and Windows. They all sign in to the same account and reach the same models, so your conversations, Projects, and history follow you between them. This guide covers what each one is actually good for — and the one thing none of them do.
The short version
- The mobile apps are for quick questions, snapping a photo of something, and continuing a conversation you started at your desk.
- The desktop app is for focused work: it can connect to tools on your computer and gets out of your browser's way.
- The web app (claude.ai) is the fallback that works on any device with a browser.
- None of them work offline. Claude is cloud-only. No signal, no Claude.
What the phone apps are good at
The iOS and Android apps do most of what the website does, reshaped for a small screen and a camera.
Snapping photos of the real world
Claude can read images, so the phone camera becomes its most useful mobile feature. Point it at a handwritten note, a nutrition label, an appliance's model number, a math worksheet, or a menu in another language, and ask about what it sees. This is genuinely handy in a way the desktop can't match.
Continuing your work anywhere
Because everything syncs to your account, a conversation you began on your laptop is waiting on your phone at the bus stop. Projects — Claude's persistent folders of context and instructions — show up too. The apps also handle file and image uploads, web search, and Artifacts (live rendered documents and small apps shown side-by-side), though a phone screen is a cramped place to read an Artifact.
Share-sheet capture
On both platforms you can share a webpage, screenshot, or file into Claude from another app. It's the fastest way to say "explain this" without copy-pasting.
What the desktop app adds
The Mac and Windows app looks like the website in a window, but it earns its place through connections. Via MCP (the Model Context Protocol), the desktop app can link Claude to tools and data on your machine and in other services — the sort of setup that's awkward inside a browser tab. It's also where computer use and heavier local workflows feel most at home, and it stays a keyboard shortcut away instead of competing with your fifty other tabs.
If you mostly chat, the desktop app and the website feel nearly identical. If you want Claude wired into your actual tools, the desktop app is the one to install.
Which surface for which job
| Surface | Best for | Weak spot |
|---|---|---|
| Mobile (iOS/Android) | Camera, quick questions, on-the-go follow-ups | Small screen for Artifacts and long docs |
| Desktop app (Mac/Windows) | Tool connections (MCP), focused sessions, computer use | Another app to install and keep updated |
| Web (claude.ai) | Any device, nothing to install | Lives among your browser tabs |
The offline reality: there isn't one
This is the honest limit worth repeating. Every Claude app is a thin client that sends your request to Anthropic's servers and shows you the reply. There is no on-device model, no offline mode, no "lite" version that runs on the plane. If your connection drops mid-answer, the answer stops. If you need something that works with no internet, or that never leaves your device for privacy reasons, a Claude app is the wrong choice — a local model on your own hardware is what you want. See local-vs-cloud for that trade-off.
Voice on mobile: manage expectations
People coming from ChatGPT or Gemini often expect to hold up their phone and have a flowing spoken conversation. As of July 2026, Claude does not offer an always-on, hands-free voice mode like ChatGPT's Advanced Voice or Gemini Live. Voice support is limited and nascent — fine for the occasional dictation, not for a walk-and-talk assistant. If real-time voice is the whole point for you, Claude isn't the tool today. Check the current state in the app and at claude.ai, since this area moves.
When a Claude app is the wrong tool
- You need it to work offline — it can't; use a local model.
- You want a spoken back-and-forth — Claude's voice is thin; ChatGPT or Gemini fit better today.
- You want it on your phone's assistant button or Siri — Claude is a standalone app, not an OS-level assistant or a smart-home hub.
- You want it to generate images — Claude reads images but has no native image generator; it can only build visuals through code.
For everything else — thinking, writing, reading documents, coding, analyzing a photo — the apps are a solid, consistent front door to the same Claude you get on the web.
