Indoor building nvigation
Navigate complex buildings with confidence. PDF floor plans, sensor fusion, and offline support — all from your phone's browser.
Choose any floor — Each rendered from high-resolution PDF plans.
GPS and inertial sensors work together to locate you on the floor plan. Altitude detection auto-selects your floor.
Pinch to zoom up to 40x, pan around the plan, and follow your position in real time with compass orientation.
High-resolution vector rendering of floor plans using PDF.js. Auto-crops borders and whitespace for clean display.
Adaptive blending of GPS and device motion sensors. Always-on inertial navigation with GPS correction based on signal accuracy.
Smooth touch-based zoom up to 40x magnification. Pan controls for both touch and mouse. Designed for detailed floor plan inspection.
Two modes: rotate the map to match your heading, or keep the map north-locked and rotate an arrow indicator instead.
Uses device altitude data to automatically detect which floor you're on and switch the displayed floor plan.
Install as a Progressive Web App. Service Worker caching means it works without network connectivity once loaded.
Wayfinder uses a sophisticated sensor fusion system designed for the challenging indoor environment of a hospital.
GPS correction strength adapts based on reported accuracy. Poor GPS signal? Wayfinder relies more on inertial tracking.
Hybrid dead reckoning using step detection, rotation rate, and lateral motion damping for accurate position tracking.
Visual position trail with quality color coding — blue for high confidence, yellow for moderate, orange for estimated positions.
Your position persists across sessions. Reopen the app and pick up where you left off without recalibrating.
Built for navigating new buildings with complete coverage across all floors.
Automatically detects and labels rooms and spaces within the building.
Automatically detects and labels exits and staircases within the building.
Find rooms, departments, and points of interest using PDF text extraction.
Automatic 3D rendering of the building layout.
Route planning with step-by-step navigation directions between locations.
Marked locations for clinics, lifts, toilets, and other key facilities.
