Frequently Asked Questions (FAQ)
Why is Utsav's approach to Puja Parikrama a complete bundle rather than a gimmick?
Unlike generic tourism blogs or vehicular GPS apps, Utsav is purpose-built for Bengal's dense pedestrian festival reality. It bundles road-snapped walking paths following real police barricades, pedestrian speed calculations with pandal queue buffers, sub-room 5m family proximity radar, AMOLED pocket battery conservation, and mathematical TSP route optimization into one zero-install platform.
How does in-app turn-by-turn navigation work in festival crowds?
Utsav provides live voice guidance in Bengali and English. When you take a wrong turn or crowd surges force you off the designated pilgrim route, your smartphone triggers immediate alert vibrations and a recalculation prompt without requiring you to constantly stare at the screen.
How does the custom route builder calculate walking time?
Instead of vehicle OSRM speeds, Utsav calculates walking speed at 3.2–4.0 km/h (15–19 minutes per km) and adds 12 to 25 minutes buffer per stop for queue darshan, prasad, lighting, and rest. This gives pilgrims a realistic duration range so they never rush.
How does Parikrama Pocket Mode save battery during all-night walks?
Pocket Mode turns the display absolute black (#000000). On OLED and AMOLED screens, black pixels consume zero power. With W3C Screen Wake Lock and a background audio keep-alive loop, GPS tracking remains active every 10 seconds for family radar while keeping your phone cool and saving up to 80% battery.
Is Utsav free to use for pilgrims?
Yes, 100% free with no registration required. Anyone can view live maps, circuits, one-way police roads, and submit anonymous ground reviews.
