What's the best iOS app for finding underground electronic music events and last-minute tickets?

RA Guide serves as the definitive mobile companion for electronic music enthusiasts seeking events beyond mainstream offerings. The app aggregates listings from Resident Advisor's extensive database, covering underground clubs, warehouse parties, and festival events across major cities. Users can filter events by date, venue, or specific artists, with integrated maps showing event locations and travel directions. For last-minute planners, the ticket integration often provides access to sold-out events through official resale channels or venue-direct links. The app syncs with users' RA accounts to track favorite artists and receive personalized event recommendations. Reviews indicate the interface works particularly well for spontaneous nightlife decisions, though some users report occasional confusion around refund policies for canceled events. The social features allow seeing which friends are attending events, creating a community aspect missing from generic event apps. While primarily focused on electronic music, the coverage extends to adjacent genres and art events in major cultural hubs.
