Stop guessing which track to play next. KeyBridge is the key reference tool built for DJs who want their sets to sound more polished - without memorizing music theory. Here's what the smoothest DJ sets have in common: the tracks share compatible keys. When the next track flows musically from the last one, every transition feels right. When it doesn't, something feels off - even if you can't explain why. KeyBridge gives you the rule in one tap. --- HOW IT WORKS --- Pick the key of your current track. KeyBridge instantly shows you three ways to go next: COUNTERCLOCKWISE (-1) - Bring it down. One step down the wheel. RELATIVE - Switch the mood. Same root, flip between major and minor. CLOCKWISE (+1) - Lift the crowd. One step up the wheel. Tap any suggestion to jump there. Chain transitions. Plan your whole set in minutes. --- WHY DJs LOVE IT --- - Works 100% offline - no signal, no lag on stage - Zero learning curve - tap and go, even mid-set - Full 24-key wheel (12 major + 12 minor) - Built for speed - 15-second auto-return keeps you focused - Haptic feedback - feel the response in your palm - Designed to disappear in the booth - dark interface keeps your eyes adjusted and the atmosphere intact - Retro DJ-hardware aesthetic that looks right next to your gear - iPhone and iPad - use it in the booth, the bedroom, or the bus --- WHO IT'S FOR --- Beginners: Finally understand why some transitions work and others don't. Build your first key-matched set with confidence. Intermediate DJs: Stop relying on memory during live sets. Read the crowd, not your notes. Producers & Remixers: Find compatible keys for mashups, bootlegs, and edits in seconds. --- FREE AND PRO --- KeyBridge is free to download. Free includes the full 24-key wheel, the three core moves (Counterclockwise, Relative, Clockwise), the Spectrum Drive theme and Keep Screen Awake. KeyBridge Pro is a one-time purchase that adds the advanced moves (Diagonal -1 / +1, +5 Lift, +7 Shift), all three colour themes and every auto-return option. No subscription. --- THE PROMISE --- Follow KeyBridge's suggestions for one set. You'll hear the difference immediately. Your transitions will feel tighter, your energy arcs will land, and the dancefloor will stay with you longer. This isn't a theory app. It's a live-performance companion. --- Built by a working DJ for working DJs. No ads. No subscriptions. No data collection. Ever.
