Early access · The first phone for your agent

Virtual phone infrastructure for AI agents.

ERIUS PHONE gives AI agents real Android phones in the cloud — devices, not phone numbers — driven over one HTTP API and MCP. Every phone is isolated, keeps its apps and sign-ins, and runs in parallel with the rest.

Call Use apps Test Audit Automate

Agents work in browsers. People live in apps.

Erius Phone is a real Android phone in the cloud that your AI agent controls over an API. It can try your app the way a user would, or use mobile apps on a phone of its own.

What it is

Not a simulator. A phone.

Two gaps, one device. If you ship an Android app, there's no easy way to see how a real user — or a real AI agent acting as one — gets through it on a real phone. And if you build agents, they're stuck in browsers and APIs, outside the apps people actually use. Erius Phone is an Android device for AI agents — a full virtual Android phone with the real operating system, real apps, real Google Play Store, real browser — that your agent uses through the same surface a person does: the touchscreen, driven by our AI agent phone API.

Real Android

The full OS boots and runs. Apps behave the way they do on a handset — permissions, notifications, keyboards, back stack and all.

Every phone also carries a Samsung S25-class device profile (model, brand and manufacturer) instead of a generic emulator default. The system underneath is Android 13.

Real apps, real store

Install from Google Play, from an alternative store, or straight from your APK. The agent's apps stay installed on its phone between sessions.

Looks before it taps

No brittle selectors written in advance. The agent reads the accessibility tree and a screenshot each step, and decides what to do from what's on screen.

One API, every gesture

Tap, type, swipe, launch, install, read, screenshot — plain HTTP calls any agent framework can make.

Real microphone input, too: the agent can play audio into any app that uses the mic — voice assistants, recording apps, voice verification flows.

Video into the camera is in opt-in beta on new devices.

Any app

Any app on Google Play. No API required.

Most apps don't publish an API your agent could call. Erius Phone doesn't need one — the agent uses the touchscreen, exactly like you do: it taps, reads, and scrolls through whatever is on screen. If you built the app yourself, it can also audit it the way a real user experiences it, not just by reading your source code.

Install it, then use it

If it's on Google Play, the agent can install it and use it — no integration, no partnership, no SDK. Some apps refuse to run on virtual devices; we'll tell you plainly when one does.

The same touchscreen you use

No hooks into the app's internals. The agent sees the screen and acts on it, the way a person would.

Audit your own app honestly

Reading your source code tells you what the app should do. The agent tells you what actually happens when someone uses it.

How it works

From APK to report in four steps.

Flow shown is illustrative; the packaged report in step 4 is coming soon. Read the real API reference →

    During early access we provision your dedicated Android device by hand and hand you its API key — running in its own isolated environment.

This is the same kind of device your agent gets, live, not a video. Tap to press, drag to scroll, and use Back and Home to get around. You get the touchscreen your agent uses.

This is a real shared Android device — one demo session at a time, 90 seconds, resets after each turn.

Use cases

Two problems it solves.

Primary

App QA, done by something that actually uses the app

2/3flows passed · example

Clicking through every flow by hand on every release is slow, and scripted UI tests break the moment a screen changes — so the bugs that slip through are the ones real users find first. Instead, give your agent an APK and a list of things a user should be able to do. It installs the build on a real Android device, works through each flow by reading the screen, and tells you where it got stuck — with the screenshot to prove it.

  • Install straight from your APK, every build
  • Flows written as goals, not selector scripts
  • Screenshot and crash log at every step, through the API
  • Coming soon: goal-based QA runs with pass/fail reports
run #42 · example · coming soon
onboarding  PASS  7 steps   7 shots
search      PASS  5 steps   5 shots
checkout    FAIL  crash at step 6
            stack trace attached

The report shown previews the packaged format we're building. Today your own agent runs the test through the device API and collects the screenshots and crash log itself.

Also

Agent automation on real Android

A lot of what people do on a phone happens inside apps that have no website and no public API — and an agent working through a browser can't reach them. On its own phone, it can: anything a person can do on Android, your agent can now do too.

  • Real apps from Google Play
  • A browser that's a real mobile browser
  • State that persists between sessions

Sign-ins stay human. Account sign-ins and other sensitive steps are done once by a person, by design. The agent works inside the session you've set up — it doesn't handle your credentials. Some apps also restrict virtualized devices; we'll tell you plainly when one does.

Now with video

Your agent has a face
and a voice now.

Call it, or have it call you — a real one-to-one video or voice call, not just text and voice notes. Conference calls with several people are coming next.

  • Call it, or it calls you

    Real one-to-one video or voice over WhatsApp or Telegram.

  • A face, not just a voice

    On a video call your agent appears as an avatar and talks with you live.

  • Coming: conference calls

    Adding it to a call with partners or clients is next on the roadmap.

Give your agent a voice

One-to-one calls over WhatsApp and Telegram.

For your own agent

Give your agent a phone of its own.

You have a phone. Your AI assistant has been living in a chat window. Give it a real Android phone — its own home screen, its own apps, its own browser — and stop lending it yours.

  • Somewhere to put its apps

    It installs apps from Google Play, and they're still there tomorrow.

  • It scrolls. It types. It taps.

    Real apps and a real mobile browser, driven by your agent over a simple API.

  • You do the sign-ins, once

    Like setting up a phone for someone new: you log in to the accounts it needs, then it takes it from there. It never handles your passwords.

Competitor prices and features change, so check the vendor's own site before you decide. Product names belong to their owners, and ERIUS PHONE is not affiliated with them.

Built for isolation

Every phone is its own phone.

Your agent's device isn't shared, pooled, or reset into someone else's hands.

Container per device
Each customer's phone runs in its own isolated container. No shared filesystem, no shared app data.
Network isolation
Every device sits on its own isolated network. Phones can't see each other.
Full control via API
Everything the agent does goes through the API — every call is explicit and scoped to your device.
Real Android
A full virtualized Android system — not an emulator skin and not a screenshot simulator.
