Tour Map is a shared map and database of halls, clubs, theatres and cultural centres for live production. Everything you need to know about the venue you're heading to, in one place — and offline too, when there's barely any signal backstage. WHAT IT DOES • Interactive map — every venue together, with filters and search • Halls and tech — power, rigging, projection, dimensions, capacity and drapes, neatly split into Lights / Sound / Other • Fixtures from GDTF — pick installed fixtures by searching the GDTF library; plus lighting consoles • 3D venue files — upload Soundvision, d&b ArrayCalc, EASE or measurements right to the hall • Ratings and visits — rate your visit so others know what to expect; records are versioned • Access and load-in — step-free access, lift, stairs, stage hands, stage and hall heights • Contacts — build a clear directory of technicians, production and operators • Photos and PDFs — gallery and technical attachments (tech rider, plans, light plots) • Restaurants nearby — where to grab a bite, with ratings and opening hours • Sharing by link + QR — anyone can open a hall's page, even without an account OFFLINE Download the offline package and the app works without a signal — place data plus a vector map. Photos are optional. FOR CULTURAL CENTRES Take over your venue, get the verified badge and your own public page with logo and colours. Free.

Verdict
The clearest difference is in-app purchases: Venue Tech Map at none against AV Flash Sync's 1. Venue Tech Map also leads on update cadence (every 4 days vs every 19 months). AV Flash Sync's advantage is iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.
