Dpi Changer for WearOS

Customize your Wear OS smartwatch display density like never before!

DPI Switcher for Wear OS gives you total control over your watch screen scaling. Whether you want to fit more content onto your round display, enlarge text for better readability, or set custom DPI scaling for specific apps, DPI Switcher makes it fast, effortless, and safe.

♿ ACCESSIBILITY SERVICE API USAGE
DPI Switcher uses the Android AccessibilityService API to enable its Per-App DPI Switching feature:
• Purpose: The AccessibilityService API is used solely to detect when an installed application opens or closes on your smartwatch. This allows DPI Switcher to automatically apply your custom per-app screen density (DPI) override when you launch an app, and automatically restore your global default density when you exit the app.
• Data Privacy: DPI Switcher does NOT use the AccessibilityService API to collect, store, or share any personal or sensitive user data. No screen content, typing, keystrokes, or personal information is ever monitored or transmitted.

⚡ KEY FEATURES
• Global Display Scaling: Change the system-wide DPI of your Wear OS watch with a single tap.
• Per-App DPI Switching: Assign custom screen density levels for individual apps (e.g., compact view for Maps, enlarged view for Messaging).
• Multi-Engine Architecture: Works seamlessly using Shizuku API, Local Wireless ADB, Root (su), or Secure Settings (Legacy).
• Standalone Smartwatch App: Runs 100% on your watch—no phone companion app required!
• Safety Recovery Countdown: Integrated 10-second auto-revert timer prevents accidental unreadable display settings.
• Boot Recovery Protection: Automatically resets unconfirmed DPI changes on system restart for bulletproof safety.
• First-Boot Guided Onboarding: Step-by-step wizard checks permissions and guides setup in seconds.
