• Guarantee Complete Data Sovereignty: Grounded in a strict Local-First architecture—all your personal records remain on your device, complemented by transparent, offline backup and restore.

A lightweight notification enhancement tool providing an intuitive floating experience for the Multitasking 'Bubbles' feature in Android 17 and lower versions (Android 11+), with no Root or Shizuku required.

• 🔔 System-Level Floating Bubbles: Freely subscribe to your most-used apps and enjoy persistent, interactive message bubbles that keep important conversations accessible.
• 📦 Smart Stacking & Expansion: Intelligently groups consecutive notifications from the same app; keeps things tidy in a compact preview and expands smoothly to display full context and actions.
• ⚡ Inherited Quick Actions: Extracts native notification actions (such as Mark as Read or Reply) to let you respond directly within the floating panel.
• 🚀 One-Tap App Jump: Tap any unread message card or bubble notification to navigate straight to the specific chat or page.
• 🎛️ Unified Notification Console: Browse, inspect, and manage all your unread messages in one centralized dashboard.

Location-based "Fog of World" Footprint Tracker & Trajectory Chronicler

Pixel World divides the globe into millions of micro-grids, silently chronicling your real-world journeys in the background and lifting the "fog of the unknown" as you move across streets, cities, and countries.

• 🗺️ Dual-Precision Tracking Engine:
  • 📍 Precise Mode (Zoom 18): Street-level resolution ideal for city walking tours, jogging, and outdoor hiking.
  • 🔋 Battery Saver Mode (Zoom 14): District-level low-power grid tracking, perfect for daily commutes, highway road trips, and high-speed rail.
• 🔋 Smart Activity Hibernation: Integrated with Google Activity Recognition. When you remain still, GPS location requests automatically sleep; the moment you begin moving, tracking wakes up seamlessly.
• 🏙️ Authentic Administrative Boundaries & Spherical Integrals: Fetches official administrative GeoJSON boundaries via OpenStreetMap Nominatim. Uses spherical polygon area line integrals rather than crude bounding boxes to calculate exact square kilometers explored.
• 🏆 Offline Achievement Engine: Automatically unlocks tier badges from Bronze to Onyx (Earth Walker, Globetrotter, Pathfinder Fever). A daily summary is pushed at 21:00 via WorkManager detailing your progress.
• 🗄️ Complete Data Sovereignty: Stored 100% locally with Room Database. Includes one-click JSON backup/restore and built-in diagnostic logging.
