Claude on Your Phone: Voice, Photos, and On-the-Go Work

Most people discover Claude on a laptop. The ones who get the most value out of it eventually realize it's just as useful — sometimes more useful — in their pocket.

Installing the Mobile App

Claude has a free app on iPhone and Android. Download, sign in with the same account, everything syncs — Projects, conversations, history. Full walkthrough in Lesson 04.

Workflow 1: Voice Capture

What it is. Tap the microphone icon and talk. Claude transcribes and responds. Not plain voice-to-text — Claude understands meaning, asks follow-ups, and produces structured output from a rambling spoken summary.

Why it matters. Most people speak 3–4× faster than they thumb-type. Driving, walking between meetings, moving between locations — voice turns dead time into captured thinking.

Field scenario: supervisor between jobs

A supervisor finishes one site at 2pm and has a 40-minute drive to the next. As he pulls out:

"We finished the Martinez job today. Took about 6 hours instead of the 5 we quoted, mostly because the attic access was tighter than the site survey showed. Crew performed well. Customer was happy. One thing to flag: there's a cracked fascia board on the south side we didn't touch — someone should tell the sales rep."

By the next site, Claude has a clean job completion note with the time overage flagged, a customer-satisfaction line, and the fascia issue broken out as a separate action item for sales. Copy into the job management system, move on.

Executive scenario: recap between meetings

She walks out of a 90-minute strategy session with 10 minutes before the next. Opens Claude in the elevator and speaks for two minutes summarizing key decisions and owners. By the next conference room, she has a clean follow-up email drafted and ready.

Workflow 2: Photo Analysis

What it is. Take a photo and send it to Claude. Claude can describe, extract text, interpret diagrams, or analyze what it sees — in plain language.

Why it matters. Photos are often faster than writing. Instead of typing out a description, take the picture.

Field scenario: damage documentation

A project manager arrives on-site and finds storm damage to rooftop equipment. She needs to send an RFI to the client documenting the pre-existing condition before her crew starts.

Three photos, then:

[attaches photos] "I'm an Empower PM. These are from a commercial rooftop job site, taken before we started work today. Draft a one-page RFI documenting pre-existing damage. Formal language, include a request for written direction before we proceed, leave a placeholder for the client's name and project number."

Formatted RFI within seconds. She fills the blanks, sends from her phone, and has a documented paper trail before her crew touches anything.

Other photo uses

• Photograph a whiteboard after planning — Claude transcribes to organized notes
• Snap a handwritten change order — Claude extracts to typed version
• Photo of a product label or spec sheet — Claude summarizes key specs

Workflow 3: Share Sheet (Forwarding Content Into Claude)

What it is. From any app — email, browser, PDF viewer, Messages — tap the share button and choose Claude. Whatever you were looking at drops into a new conversation.

Why it matters. No copy-paste. Stuff lands in your email or a document app, and you route it straight to Claude without switching back and forth.

Scenario: summarize an email on the go

Long vendor email. Ninety seconds before a meeting. Open the email, tap share, select Claude:

"Summarize in three bullets. Tell me if there's anything I need to respond to today."

Summary before you walk into the room.

Scenario: review a PDF proposal on the go

Proposal lands as a PDF. You're not at your desk. Open the PDF, share → Claude:

"What are the payment terms and total contract value? Anything unusual vs. a standard proposal?"

Two or three things you actually need, no scrolling through 40 pages.

Privacy on Mobile

Same rules as desktop. Claude sees what you share — the photo, the text, the document. It doesn't have access to your camera roll, contacts, or anything else unless you explicitly share it. Full detail in Lesson 14.

Tips

• Keep instructions short. On mobile you're usually in a hurry. One clear sentence of direction > a paragraph.
• Open your Project first. If you're in the field regularly, open your role Project so Claude already has your context.
• Voice first, refine second. Dictate the raw thing. Then ask: "That was a job recap — pull the action items as a numbered list."
• Test the share sheet once. First time you try sharing from another app to Claude, do it deliberately. Thirty seconds to learn; you'll use it constantly after.

Try This Now (3 min)

Right now, on your phone:

1. Take a photo of anything written — a receipt, a business card, a handwritten note.
2. Open Claude, attach the photo, ask: "What's on this and what should I do with it?"
3. Then open any email and use Share → Claude on it.

You've just used two workflows that catch most people off guard.
