hapjam shows you live music happening right now, near you. Not arena tours — the everyday live music at the bars, breweries, patios, wineries, and restaurants around you. See who's on stage tonight, who's playing right now, how far it is, and when the music starts — all in one place, updated in real time. WHY HAPJAM • Live, not stale — real venue schedules updated continuously, so you never show up to a canceled show or last week's flyer. • Built around tonight — the feed leads with what's on now and coming up today near you, not a giant calendar to dig through. • Discover, don't search — find venues and performers you've never heard of, playing five minutes away. • Free for fans, always. WHAT YOU CAN DO • See what's playing live right now and tonight near you, sorted by distance. • Browse by area, or filter venues by vibe — on the water, breweries, outdoor, no cover. • Open any venue or performer for their full schedule, set times, and directions. • Follow your favorite bands and venues and get a heads-up when they're playing near you. • Ask for a vibe — "acoustic on a patio, no cover" — and get real picks from what's actually on tonight. FOR VENUES & PERFORMERS Own a venue or play out? Get listed free, claim your page, and put your live schedule in front of people the moment they're deciding where to go tonight.

Verdict

On ads, in-app purchases, device support and iOS requirement there is nothing between them.
