Google Antigravity IDE on iPhone — What Works Today
Short answer: the Antigravity IDE itself doesn't run on iPhone — it's desktop software for Windows, macOS, and Linux. What works today is connecting your iPhone to the Antigravity session on your computer through a companion app. With ZeroG, that gets you live agent chat, a streaming terminal, and the ability to approve and redirect your agent from iOS — but not the full desktop editor, and not without your computer running.
The state of things in August 2026
Google hasn't shipped a mobile version of Antigravity, and nothing suggests one is imminent — the product is built around a full desktop editor with an AI agent working in your local project. So "Antigravity on iPhone" in 2026 means one thing in practice: a companion app that connects to the desktop IDE and puts the parts that matter on your phone. ZeroG is that companion — an iPhone app paired with an extension running inside Antigravity on your computer. It is not a standalone coding tool; without the desktop IDE running, there's nothing for it to connect to.
What works today
- Agent chat, live. Talk to your Antigravity agent in natural language from the phone. Your messages are injected into Antigravity's chat on the desktop, and replies stream back token by token.
- Streaming terminal. stdout, stderr, and exit codes from your computer stream to the phone line by line — build logs, test runs, and errors as they happen.
- Running commands. Terminal commands you type on the phone execute on your computer, with output streamed back.
- Approvals and steering. When the agent pauses with a question, you answer from the phone; you can also redirect it or tell it to stop. More on remote approvals here.
- Status at a glance. Mission Control shows your agent, recent commands, and connection state in one dashboard screen.
- Anywhere connectivity. Wi-Fi or cellular, through an encrypted relay — no tunnel or VPN to configure. Your code and AI model stay on your own machine.
- Reliability plumbing. Auto-reconnect, missed-message recovery, and offline buffering for spotty connections.
What doesn't work (yet, or by design)
- The full editor UI. You interact through chat and terminal — there's no file-tree browsing or side-by-side diff editing on the phone. For reviewing a large change line by line, you'll still want the desktop.
- Cold starts. Your computer must be on with Antigravity open. A companion reaches a live session; it can't wake a machine that's off or asleep.
- iPad-specific layout. ZeroG is an iPhone app; it runs on iPad in iPhone compatibility mode rather than a tailored tablet layout.
- Android. Not yet — Android support is planned.
What you need
- An iPhone on iOS 15.1 or later with the free ZeroG app
- A computer running the Google Antigravity IDE (Windows or macOS for the ZeroG extension)
- The ZeroG extension installed in Antigravity — Extensions panel → search ZeroG → Install
Pairing the phone to the desktop takes about a minute; the setup guide covers every step. ZeroG is free with ads on one paired device; Pro ($19.99/month) removes ads and adds unlimited devices.
Is it worth using?
If your Antigravity agent runs tasks longer than a coffee break, yes — the phone turns dead waiting time into quick check-ins, and stalled approval prompts get answered in seconds instead of hours. If you mainly do short, interactive sessions at your desk, you won't need it often. The honest framing: ZeroG doesn't put the IDE on your phone, it puts your agent on your phone — and for long-running agentic work, that's the part you actually need while you're away.
ZeroG is the mobile companion for the Google Antigravity IDE — available now on the App Store.

Can I run the Google Antigravity IDE on an iPhone?
Not directly — Antigravity is a desktop IDE for Windows, macOS, and Linux, and there's no iOS version. What you can do today is connect your iPhone to the Antigravity session running on your computer with a companion app like ZeroG, which streams the agent's chat and terminal to your phone and sends your input back.
What actually works from an iPhone today?
Chatting with your Antigravity agent with live streaming replies, watching terminal output (stdout, stderr, exit codes) in real time, running terminal commands on your computer, answering the agent's questions and approving or redirecting its work, and checking session status — over Wi-Fi or cellular.
What doesn't work from an iPhone?
You don't get Antigravity's full desktop editor UI on the phone — no file-tree browsing or side-by-side diff editing — and you can't start Antigravity remotely on a computer that's off or asleep. The desktop IDE must already be running.
What do I need to use Antigravity from an iPhone?
Three things: an iPhone on iOS 15.1 or later with the free ZeroG app, a computer running the Antigravity IDE, and the ZeroG extension installed in Antigravity. Pairing them takes about a minute.
Is there an Android version?
Not yet — ZeroG is iPhone-only today, with Android support planned.
