What’s the bottom line on the Claude app?
Claude is available on five platforms: the web app at claude.ai, the iOS app (iPhone and iPad), the Android app, the Claude Desktop app for Mac and Windows, and Claude Code for developers working in the terminal. Every platform syncs conversations through your Anthropic account. The free tier works on all platforms with daily message limits, while Claude Pro ($20/month) unlocks 5x more usage, and Claude Max ($100-$200/month) removes practical limits. If you only use one platform, start with the web app. If you code, add Claude Desktop for MCP integration and local file access. If you want Claude in your pocket, grab the mobile app for voice mode on the go.
What are the key takeaways?

- Free on every platform — the free tier gives you access to Claude Sonnet with daily message limits across all apps
- Desktop unlocks MCP — Claude Desktop is the only GUI app that supports the Model Context Protocol for connecting to local tools, files, and databases
- Voice mode is free — as of early 2026, voice conversations are available to all users on iOS and Android with five voice options

What can you do in the Claude web app at claude.ai?
The Claude web app is where most people first meet Anthropic’s AI assistant. It runs in any modern browser — Chrome, Firefox, Safari, Edge — with no download required. As of March 2026, Claude has roughly 18.9 million monthly active users worldwide, and the web app handles the lion’s share of that traffic.
What You Get in the Web App
The web interface gives you access to the full Claude model lineup. Free users get Claude Sonnet (the balanced model), while Pro subscribers can switch between Sonnet, Haiku (fast and lightweight), and Opus (the most capable model). The interface supports text conversations, image analysis (upload screenshots, photos, or diagrams), file uploads (PDFs, CSVs, code files up to 30MB), Artifacts (interactive code previews, documents, and visual outputs), and Projects for organizing related conversations with persistent context.
One standout feature is web search, which lets Claude pull real-time information from the internet during conversations. This is available on all plans, though Pro and Max users get priority access. You can also create and share Artifacts — self-contained pieces of content like code, documents, or interactive visualizations that Claude generates alongside its responses.
When to Use the Web App
The web app is ideal for long research sessions, document analysis, and any task where you want a full-screen workspace. It is the best choice when you need to upload large files, work with Artifacts, or manage Projects. If you are trying Claude for the first time, start here — no app installation, no credit card, just go to claude.ai and sign up.
What can you do in the Claude iOS app?
The Claude iOS app is available for iPhone and iPad through the Apple App Store. It launched in May 2024 and has steadily gained features to reach near-parity with the web experience. The app holds a 4.6-star rating with over 152,000 reviews on the App Store.
Key iOS Features
Voice mode is the headline mobile feature. You can speak to Claude and hear responses in one of five voice options: Buttery, Airy, Mellow, Glassy, and Rounded. Voice mode launched as a Pro-only feature in May 2025 and became free for all users in early 2026. It supports seamless switching between voice and text within the same conversation.
Beyond voice, the iOS app supports camera integration (snap a photo and ask Claude about it), file sharing from other iOS apps via the share sheet, Siri Shortcuts for launching Claude actions with voice commands, Reminders integration, and Artifacts viewing. You can also use health data analytics on iOS, letting Claude analyze Apple Health data with your permission.
