Spacesuit is an independent remote companion for Google Antigravity running on a Mac. Its official description brings projects and conversations to an iPhone or iPad so instructions, progress and responses can be inspected away from the computer. This first look uses the App Store listing, not a remote-development or security test.
The audience is someone who already uses Antigravity on a compatible Mac and wants a mobile control surface. The important boundary is where the work happens. A phone can relay an instruction while the Mac remains the execution environment, with the same files, tools and responsibilities. Remote convenience does not turn a real workspace into a disposable sandbox.
Based on official store information. We have not tested this app hands-on.
What it does
The described controls include browsing Mac projects, opening existing conversations and starting a new conversation in a selected workspace. Prompts can be sent from the mobile device, a follow-up queued while Antigravity is busy, and supported tasks stopped or continued. Those are workflow capabilities, not proof that every Antigravity version or action is supported identically.
Model selection uses the models available on the Mac. Supported reasoning, code and tool activity can be inspected, while Live Activities expose running-task information on the Lock Screen and Dynamic Island. A status surface can help awareness without replacing a full review of changed files or command results. We have not tested which activity details appear in every case.
The connection uses a companion Mac app and the user's private iCloud account. Antigravity credentials stay on the Mac according to the developer. Both devices must use the same Apple account, and the Mac must remain awake with Spacesuit and Antigravity running. Internet access is required for remote iCloud communication. This is not described as a standalone mobile coding engine.
Before you install
Begin with a harmless project and a bounded task. Confirm the selected workspace before sending instructions, then inspect the result on the Mac. We have not tested synchronisation, stop behavior, task recovery or command scope. A mobile response should not be treated as proof that every intended file changed correctly or that an operation was reversed.
A queued follow-up needs a clear relationship with the task already running. A new instruction can be sensible when written and become inappropriate after an unexpected result. Review what actually happened before allowing a sequence to continue. The listing does not establish a universal approval or rollback system for all underlying tool actions.
Account and device access deserve deliberate review. Private iCloud is a stated transport arrangement, not an independent security audit. A Lock Screen status can reveal project information to someone nearby, while the Mac's own credentials and permissions determine what work can be reached. Keep sensitive material out of an initial demonstration and inspect the actual privacy controls.
Price and access
The retained US App Store offer lists a free download. Some features require Spacesuit Unlimited, offered as an annual subscription or a one-time lifetime purchase. The description mentions theme colors, title fonts and app icons among Unlimited customisation features, but does not establish the full free-tier boundary or exact regional prices.
Confirm the current purchase screen and compatibility requirements before upgrading. The annual plan renews automatically unless cancelled, while the lifetime option is a different access arrangement. Antigravity access, its available models and any underlying service costs are separate from installing the remote companion. Spacesuit is not affiliated with or endorsed by Google.
Our take
Spacesuit's strongest proposition is continuity with an existing Mac session. Opening a conversation and inspecting progress can be useful when the next action is small and clearly scoped. The value is not that a phone replaces a development environment, but that it offers a deliberate route into the environment already running elsewhere.
We have not tested reliability, accessibility, privacy, security or compatibility. Our take is to validate one complete remote exchange with a safe sample, then compare the displayed result with the actual workspace. Choose it when the connection requirements and action boundaries are understandable, not simply because remote control is available.
Stopping a task is particularly worth evaluating before relying on it. A stop request and a confirmed stopped process are different states, and work already performed may remain. The listing describes supported controls without proving how every underlying action behaves at interruption. Keep a suitable independent version history for valuable projects.
The same caution applies to model selection. Choosing from available models is an interface capability, not a guarantee that the models have identical behavior or terms. The remote app should make the current context clearer rather than encourage treating every response as interchangeable.
For independent professionals, the practical appeal may be checking a known task while away from the desk. That is a narrower and more defensible use than assuming a mobile screen makes every consequential development decision comfortable. The original Mac workspace remains the place where the resulting work should be reviewed and validated.
