on{X}

Your phone is smart. Now make it smarter.
on{X} by Microsoft Corporation transforms your Android device into an automated command center, letting you program it to react to real-world triggers—time, location, battery level, network state, and more. This is not a simple launcher or a wallpaper pack. This is a rules-based automation engine that executes predefined actions without manual input.

Core automation capabilities
The app operates on a simple trigger-action logic. You define conditions (e.g., "Wi-Fi connected to 'Home' network") and assign actions (e.g., "Set ringtone volume to 30%"). The engine runs in the background, constantly monitoring sensor and system data. Supported triggers include:

• Time-based: Sunrise, sunset, specific hours, or recurring intervals
• Location-based: Geofence entry/exit using GPS or network triangulation
• Device state: Battery level thresholds, charging status, screen on/off, docked/undocked
• Connectivity: Wi-Fi SSID match, Bluetooth device pairing, cellular network type change
• Sensor events: Proximity, accelerometer movement, light level changes

Actions cover nearly every system setting and app control:

• Audio: Ringtone, media, alarm, and notification volume levels; silent/vibrate/normal modes
• Display: Brightness level, auto-brightness toggle, screen timeout duration
• Connectivity: Wi-Fi on/off, Bluetooth on/off, mobile data toggle, airplane mode
• Messaging: Send SMS, compose email, post to social media via intent
• App control: Launch an app, kill a process, open a specific URL
• User interface: Show a notification, speak text aloud via TTS, lock the screen

Rule management interface
You create, edit, enable, and disable rules from a clean list view. Each rule displays its trigger summary and action list. Long-press to duplicate, share, or delete. A built-in debug mode logs every rule firing event, showing timestamps and trigger data for troubleshooting.

Scripting for power users
Beyond simple condition-action pairs, on{X} offers a JavaScript-based scripting engine. You can write custom scripts that access device APIs directly—reading sensor values, performing calculations, and chaining multiple actions with conditional logic. This opens possibilities like:

• Logging GPS coordinates every 10 minutes to a file
• Sending an email alert when battery drops below 20% and you leave a geofence
• Automatically switching to 2G network when screen is off to save power

Key advantages

• No root required – Works on stock Android 10 and above
• Background persistence – Rules survive app restarts and device reboots
• Low battery footprint – Engine uses minimal resources when idle
• Export/import rules – Share your automation setups via .json files
• Community library – Access user-submitted scripts and rule templates

Quick-start examples

• Set ringer to silent when you enter work geofence (8 AM–5 PM only)
• Turn off Wi-Fi and lower brightness when battery hits 15%
• Launch Spotify and set media volume to 70% when you connect car Bluetooth
• Send a "I'm on my way" SMS when you leave home after 6 PM
• Speak the current time aloud when you pick up the phone between 2 AM and 6 AM

Heads up: you'll need wifi for most features. Some cool stuff is extra.
