Oh My Android

[Oh My Android app icon: a surprised Android robot]

Oh My Android

Test your Android app in dark mode, big fonts, RTL and TalkBack: one click each, no adb commands.
A free, native ADB GUI for Mac that docks next to the Android Emulator. Works with real phones too.

[Latest release] [Homebrew cask] [macOS 26 or later, Apple silicon] [Featured in Android Weekly #747] [MIT license] [GitHub stars]

[Demo: the Oh My Android panel beside the Android Emulator switches dark mode, font size and language to Arabic RTL, then simulates an incoming SMS and call]
_{Dark mode, font size, Arabic RTL, incoming SMS and call. Each is one click.}

Install

brew install --cask ateymoori/tap/oh-my-android

_{Or the signed, notarized zip from Releases · macOS 26 Tahoe+ · Apple silicon · uses the Android SDK you already have (details) · ⭐ star to help more Android devs find it}

• 🎛️ Nearly 50 test actions, always visible. Dark mode, font and display size, language and locale incl. RTL and pseudo-locales, TalkBack, bold text, layout bounds, show taps, animations off, network speed, GPS, incoming call and SMS. Each icon shows the device's real state.
• 📐 Layout Inspector in dp, for any app. Hover a view to see its size and the gaps around it in dp, for Compose and Views alike. Drop your Figma export on top to compare design and build. ⇧⌘A numbers the TalkBack stops and flags missing labels and touch targets under 48 dp.
• 🗄️ Your debug build, without adb. Read SharedPreferences and SQLite, clear data, open deep links, drag an APK to install, reset permissions.
• 🪶 Native and light. SwiftUI, event-driven, no Electron, no telemetry. Free and open source (MIT).

Why not just Android Studio? Studio's Device UI shortcuts already give one-click dark mode, font size, app language and TalkBack (API 33+). Use them when Studio is open. Oh My Android adds one always-visible panel for emulators and phones that works with Studio closed, toggles the shortcuts don't have (bold text, pseudo-locales, layout bounds, show taps, animations), and dp measurements on any app, where Studio's Layout Inspector needs a debuggable one. Compared with Studio, scrcpy and mobile-mcp: docs/COMPARISON.md.

🤖 Using Claude Code, Codex or Cursor? The app ships an MCP server (18 tools) so your agent can screenshot the emulator in dp, tap, and switch dark mode or RTL. Set it up →

Features

Destructive actions (Clear data, Uninstall, Reset permissions) ask before they run.

Updates and requirements

Besides Homebrew, you can download the zip from the latest release, unzip it, and move Oh My Android.app to Applications. The app is signed and notarized by Apple.

Updates: when a new version is out, a dot shows on the menu bar icon. Click Update to … in the menu, read what's new, and install in one click. The app never updates without asking. It checks once a day; turn it off in Settings → Updates. brew upgrade --cask oh-my-android works too.

Requirements: macOS 26 Tahoe or later, Apple silicon, and the Android SDK from Android Studio (or brew install --cask android-commandlinetools). The app finds the SDK by itself. If yours is in an unusual folder, pick it in Settings → Android SDK.

No more adb commands

Every icon replaces a command you would otherwise type or search for:

Layout Inspector

Freeze the screen and measure it like in Figma. Works with Jetpack Compose and classic Views.

[Layout Inspector: hover views to see their size in dp and the distances between them]

• Hover any element to see its size in dp. Click one, hover another, and see the distance between them (gaps between siblings, paddings inside a parent).
• 8 dp grid, color picker (hex, ⇧⌘C to copy), and an estimated text size in sp.
• Design overlay: drop a Figma PNG export on the window, choose 1× / 2× / 3× or Fit width, set the opacity or use Difference blend, and nudge it with the arrow keys. Compare design and build pixel by pixel.

Accessibility audit

Press ⇧⌘A in the Layout Inspector. Every screen-reader stop gets a number in approximate TalkBack order, with what TalkBack announces and a list of problems: unlabeled buttons, images without a content description, and touch targets smaller than 48 × 48 dp.

Data Inspector

Browse the SharedPreferences (key, type, value) and SQLite databases (tables, first 500 rows) of any debuggable app, with search. It uses adb shell run-as, the same access Android Studio uses, so release builds stay closed. It is read-only: nothing on the device changes.

AI agents (MCP)

Oh My Android includes an MCP server, so your AI coding agent can see and drive the emulator: screenshot, read the UI tree in dp, tap and type, switch to dark mode or RTL, read logcat and the app's database. The agent can build a screen, run it, look at the result, and fix it by itself.

[AI Agents settings: Off, Read only or Full control, and the setup command for each agent]

[Add Oh My Android MCP server to Cursor] [Install Oh My Android MCP server in VS Code]

The buttons use the Homebrew path /opt/homebrew/bin/ohmyandroid-mcp. With the zip install, use the menu bar setup below.

Set up in one step: menu bar icon → AI Agents → Set Up…, choose your agent, click Copy (or Add to Cursor / Add to VS Code). Or by hand:

claude mcp add --scope user oh-my-android -- ohmyandroid-mcp   # Claude Codecodex mcp add oh-my-android -- ohmyandroid-mcp                 # Codex CLIgemini mcp add --scope user oh-my-android ohmyandroid-mcp      # Gemini CLI

{ "mcpServers": { "oh-my-android": { "command": "/Applications/Oh My Android.app/Contents/MacOS/ohmyandroid-mcp" } } }

The JSON works in Cursor, Claude Desktop, Windsurf, Gemini CLI and other agents (VS Code uses "servers"). Homebrew puts ohmyandroid-mcp on your PATH. With the zip install, use the full path above.

Other ways to add it:

• Claude Code plugin: /plugin marketplace add ateymoori/oh-my-android, then /plugin install oh-my-android@oh-my-android
• Claude Desktop extension: open oh-my-android-<version>.mcpb from the latest release
• MCP Registry: listed as io.github.ateymoori/oh-my-android

You stay in control: menu bar icon → AI Agents → Off, Read only or Full control. The server checks it on every call, so a change applies at once. Tools that can lose data are marked destructive, so your agent asks you first.

Ready-made prompts: accessibility_review, ui_matrix (dark mode, large fonts, RTL, pseudo-locales) and debug_crash.

Try asking your agent:

• "Take a screenshot of the emulator and check this screen in dark mode."
• "Open the app, go to Settings, and check it in dark mode, font scale 2 and Arabic. Fix what breaks."
• "The app crashes when I tap Save. Reproduce it, read the crash, and fix it."
• "Audit the login screen for TalkBack and fix the problems in the code."

Built for models: every position is in dp, like your layout code. Output is compact text: a UI tree is about 10× smaller than the raw uiautomator XML, and all 18 tool definitions take about 3k tokens. The server supports MCP 2026-07-28 and the earlier versions (2024-11-05 to 2025-11-25) over stdio, has no dependencies, and needs no network.

Privacy and security

• 🔒 No analytics, no telemetry, no account. The only network request of its own is the update check: once a day it reads a small feed from this repo's GitHub releases. It sends nothing about you or your devices. Turn it off in Settings → Updates.
• Updates (Sparkle) install only when you choose, and only if they are signed with this project's EdDSA key and the same Developer ID.
• Talks only to the adb of your own Android SDK. Text you type is shell-quoted before it reaches the device.
• Database copies from the Data Inspector are deleted when you reload and when the app quits.
• The MCP server runs only when your AI agent starts it, and only with the access you allow. What it reads (screen, UI, logs, app data) goes to your agent, and from there to the agent's model provider.
• Signed with a Developer ID, hardened runtime, notarized by Apple.

Found a vulnerability? See SECURITY.md.

Troubleshooting

• adb not found: pick your SDK in Settings → Android SDK, or set ANDROID_HOME.
• The agent says there is no device: start an emulator or connect a phone, then ask the agent to run list_devices.
• Agent cannot start ohmyandroid-mcp (zip install): only Homebrew puts it on your PATH. Use the full path /Applications/Oh My Android.app/Contents/MacOS/ohmyandroid-mcp.
• Homebrew says the tap is not trusted: Homebrew 6 and later ask you to trust third-party taps. The full brew install --cask ateymoori/tap/oh-my-android trusts only this cask. For short names, run brew trust --cask ateymoori/tap/oh-my-android first.
• The agent gets "Access is Off": menu bar icon → AI Agents → Read only or Full control.
