π In One Sentence
PhoneClaw is a free, open-source (Apache-2.0) iOS app that runs Gemma 4 and MiniCPM-V AI models fully on-device to act as a local phone agent, handling calendar, reminders, contacts, clipboard, health data, and camera input without sending that data to a cloud server.
π¬ In Plain Terms
Instead of sending a request to a cloud AI service, PhoneClaw runs the AI model directly on your iPhone. It can then look at your calendar, take notes, read your camera feed, or manage reminders, with the processing happening on the device rather than a remote server.

What Is PhoneClaw?
PhoneClaw is an iOS app that turns an iPhone into a local AI agent runtime. Its GitHub repository describes it as software that "turns phones into local AI agent runtimes with on-device models, native mobile Skills, LiveLand, and optional Mac Gateway inference."
- Core function: run an AI agent directly on an iPhone, using on-device models to read and act on calendar, reminders, contacts, clipboard, health data, and live camera input
- Inference: Gemma models run via Google's LiteRT-LM format (
.litertlmfiles); voice-related models use the ONNX format - Distribution: an iOS app, distributed primarily via Apple TestFlight, with the source available to build manually
- Developer: an individual open-source maintainer (GitHub user
kellyvv), not a company - Licensing: Apache-2.0, a permissive open-source license
Which Models Does PhoneClaw Run On-Device?
PhoneClaw ships with three on-device model options, each suited to a different hardware tier and task, per its own GitHub README.
Gemma 4 E2B
- Best For / Hardware:
- Lightweight: chat, translation, single-turn queries. Runs on iPhones with an A16 chip or newer.
Gemma 4 E4B
- Best For / Hardware:
- Full-featured: multi-turn tool conversations and complex agent flows. Recommended for iPhone 15 Pro and newer.
MiniCPM-V 4.6
- Best For / Hardware:
- Multimodal: image Q&A and real-time camera understanding in LIVE Mode. An A17 Pro chip or newer is recommended.
One documented limitation: on sideloaded (non-Xcode, non-TestFlight) installations, the memory cap imposed by sideload signing means the E4B model can only run on CPU β GPU acceleration fails in that configuration. PhoneClaw's own README recommends the E2B model for sideloaded installs and a proper Xcode or TestFlight build for the best performance with E4B.
What Can You Do With PhoneClaw?
Beyond running models on-device, PhoneClaw wraps them in several agent-oriented features, quoted below from its own GitHub README.
- LiveLand β launch PhoneClaw from the Dynamic Island, home screen widgets, lock screen widgets, Shortcuts, or Control Center; the on-device model "listens, understands your request, runs the task, and shows the result right there"
- LIVE Mode β a real-time voice interaction mode with natural conversation flow and barge-in interruption, plus live camera input so the model can recognize objects and scenes in real time
- Native mobile Skills β a file-driven system using Markdown definitions to extend what the agent can do
- Mac Gateway β pairs with a Mac on the same local network to route requests to Mac-side Ollama, Codex CLI, or Antigravity CLI models for tasks too large for on-device inference
- Device integrations β calendar, reminders, contacts, clipboard, and health data, each requiring explicit user authorization per Apple's permission system
- Resumable model downloads β large model files can be downloaded directly on-device, with the download resumable if interrupted
- Bilingual UI β English and Chinese interface language support
Get PhoneClaw (TestFlight or Manual Build)
PhoneClaw is distributed primarily through Apple TestFlight, with the source code also available to build manually for developers comfortable with Xcode.
TestFlight (recommended)
- Steps:
- Join via the official TestFlight link and install through the TestFlight app.
Manual build
- Steps:
git clone https://github.com/kellyvv/phoneclaw.git, thencd phoneclaw,pod install, andopen PhoneClaw.xcworkspacein Xcode; sign with your own Apple ID and deploy to a connected device.
Model download (manual build only)
- Steps:
- Install the Hugging Face CLI (
brew install hf), then runhf download litert-community/gemma-4-E2B-it-litert-lm gemma-4-E2B-it.litertlm --local-dir ./Models(or the equivalent for other models) before building.
Requirements: iOS 17.0 or later to run the app; macOS with Xcode 16 or later, plus CocoaPods, if building manually. A real physical device and an Apple Developer account (free or paid) are needed for manual builds, since PhoneClaw is not available on general App Store. There is no Android version.

Cost
- Detail:
- Free. There is no paid tier or subscription for PhoneClaw itself.
License
- Detail:
- Apache-2.0, a permissive open-source license, per the repository.
On-device models
- Detail:
- Gemma 4 E2B, Gemma 4 E4B (via LiteRT-LM), and MiniCPM-V 4.6 (multimodal).
GitHub activity
- Detail:
- 1,244 stars, 168 forks, last code push August 6, 2026, per the GitHub API.
Verify current requirements and the TestFlight link directly on the GitHub repository before installing β a TestFlight beta can reach its tester-slot limit or be replaced with a new link, and a small, individually maintained project can change its setup steps between releases.
PhoneClaw vs. Other AI Agent Tools
PhoneClaw sits in the broader category of autonomous AI agents β tools that let a model take actions rather than just answer questions β though it is unusual in targeting a phone's own native functions specifically. Here is how it compares to other agent tools in the Local LLM Software Directory.
- Msty Go β a cross-platform local AI chat and agent app; unlike PhoneClaw, it is not focused on controlling a phone's native calendar/reminders/camera functions specifically. See the Msty Go review.
- Open Interpreter β an open-source agent framework that lets a model execute code and control a computer via natural language, aimed at desktops rather than phones. See the Open Interpreter review.
- Agent Zero β a general-purpose, self-hosted autonomous agent framework for computer tasks, not phone-specific device integrations. See the Agent Zero review.
- Leon AI β an open-source personal assistant framework you self-host on a server, rather than an on-device iPhone app. See the Leon AI review.
Who Should Use PhoneClaw?
Whether PhoneClaw fits depends on whether you own a compatible iPhone, want an agent that acts on native phone functions, and are comfortable with a small, individually maintained open-source project.
Common Mistakes When Evaluating PhoneClaw
Most confusion around PhoneClaw comes from underestimating its hardware requirements or misunderstanding its distribution method.
