Made for thumbs

Every app was built for a thumb. Your agent has none, so thumbs lends it a real iPhone.

What a real iPhone gives your agent

It installs real apps from the App Store.

A simulator can’t run App Store apps. A real iPhone runs every one of them.

It sees every button, numbered.

One look returns the screen and everything tappable on it, in 0.3–0.9 s.

It reads SMS codes on its own number.

Your own iPhone comes with a Spanish eSIM for verification codes.

It stays yours alone.

One iPhone per customer. Your sessions never meet another agent’s.

Questions

Which agents can use thumbs?

Any agent that speaks MCP over HTTP with sign-in. We test with Claude Code: run claude mcp add --transport http thumbs https://mcp.usethumbs.com/mcp, then /mcp to sign in with Google. In the Claude app, add the same URL as a custom connector.

Is it a real iPhone?

Yes. It sits on a desk in Spain, plugged into a Mac. Your agent drives it through Apple’s own testing framework, so it taps and types the way a person does. The replay at the top of this page was recorded on the iOS Simulator.

What does my agent get back?

A screenshot and a numbered list of everything it can tap, with labels and positions. It can tap by number or by point, type, swipe, scroll, open apps and links, press the home button and answer system alerts.

Can it use my accounts?

On your own iPhone, yes: sign in once and the phone keeps the session. On early access the phone is shared between testers, so don’t sign in to anything personal there.

Where are the phones?

In Spain, in the EU, on Spanish networks and the Spanish App Store.

What doesn’t work yet?

Banking and Apple Pay apps, which need a passcode the phones don’t have, and anything that asks for Face ID.

Is this allowed by the apps?

thumbs is for your own accounts and your own apps. We don’t hide that an agent is driving and we don’t help anyone get around an app’s rules. No spam and no fake accounts.

How fast is it?

Measured on an iPhone 17 Pro: a screenshot comes back in about 63 ms, a full look at the screen with its element list in 0.3–0.9 s, and a tap takes 0.4–0.8 s depending on the app.

Hand it the phone

Sign in with Google. If you’re on the list, your agent gets its URL at once. If not, you’re in line and we’ll write to you.
