Not every tool has a mobile app. And not everything works the same on your phone as on your computer. This matters, because you will want to use some of these tools on the go. Here is the current state as of March 2026.

Tools With Native Mobile Apps (iOS and Android)

Claude: Full-featured mobile app on iOS and Android. Voice mode, camera integration (photograph a document and ask questions about it), and conversations sync across all devices. Mobile-exclusive features include Siri Shortcuts (iOS) and home screen widgets (Android). However: Cowork runs on desktop only (Mac and Windows). Inline visualizations (charts, infographics) are desktop only for now. Projects are easier to set up and manage on desktop. As of March 2026, Cowork can also control your computer directly -- opening files, navigating your browser, and running tools autonomously (currently in research preview). Use mobile for quick questions, voice interaction, and camera-based tasks. Use desktop for deep work, long documents, and Cowork.

ChatGPT: Full-featured mobile app on iOS and Android. Excellent voice mode (genuinely conversational). Camera integration. All models available. Custom GPTs work on mobile. Similar to Claude: mobile is great for quick tasks and voice, desktop is better for long sessions and complex work.

Google Gemini: Full-featured mobile app on iOS and Android. Voice mode (Gemini Live) allows natural back-and-forth conversation. Camera integration for visual identification. Deep integration with Google apps on mobile. On Android, Gemini can replace Google Assistant as your default assistant, making it accessible from any screen.

Perplexity: Mobile app available. Good for quick research on the go. Also has the Comet browser (Mac and Windows).

CapCut: Excellent mobile app (this is where it started, as a TikTok companion). Desktop app available too. Some AI features are available on mobile before desktop. For quick social media edits, mobile is genuinely good.

Suno: Mobile app available. You can generate songs on your phone, which is surprisingly satisfying.

Runway and Kling AI: Both have mobile apps. Video generation works on mobile but previewing and managing clips is easier on a larger screen.

ElevenLabs: Mobile app available for text-to-speech and voice generation.

Otter.ai: Mobile app available and useful for recording in-person conversations or meetings on the go.

Manus: Mobile app available for monitoring and managing autonomous tasks.

Web Only (No Native Mobile App)

NotebookLM: Web only. No mobile app. Works in a mobile browser but the experience is better on desktop, especially for uploading and managing sources.

Gamma: Web only. You can view presentations on mobile but creating and editing is a desktop experience.

Midjourney: Web app and Discord. No native mobile app, but the web interface works in mobile browsers and Discord has a mobile app.

Bolt.new and Lovable: Web only. Building apps on a phone screen is not practical. These are desktop tools.

Ideogram: Web only, though it works in mobile browsers for quick image generation.

MyAIDrive: Web based. Also available as a Custom GPT within ChatGPT.

The Practical Takeaway

Install the Claude, ChatGPT, and Gemini mobile apps. They are genuinely useful on your phone for voice conversations, quick questions, photographing things for analysis, and continuing work you started on your computer. Install Perplexity if you use it for research. Everything else you can access through your browser when you need it.
