What's the best Android app for navigating convention floors and scanning interactive codes without internet?

PAX Nav is an Android application tailored for event-goers who need reliable access to maps and interactive features in environments with poor connectivity. Designed specifically for conventions and expos, it stores essential data like floor plans, schedules, and exhibitor details directly on the device. This eliminates the frustration of searching for a signal in crowded venues. Key features include detailed offline maps with zoom and search functions, integrated QR code scanning for unlocking exclusive content or participating in scavenger hunts, and real-time schedule updates that sync when internet is available. In practice, attendees can quickly locate booths, plan their day, and interact with exhibits without data delays. User feedback highlights the app's utility; one review notes, 'Having all the info stored locally saved me from missing panels when the Wi-Fi dropped.' However, the app's effectiveness may vary if not optimized for non-PAX events, and some users mention occasional lag when loading high-resolution maps. Overall, PAX Nav delivers a dependable solution for offline convention navigation, though its niche focus means it might not cover every event type.
