DJ BPM Assistant

DJ BPM Assistant is the precision toolkit built for the booth — BPM calculation, harmonic mixing, and genre transition guidance, all in one place. Works fully offline, no account required.

——— BPM CALCULATOR ——— Enter any BPM and instantly see every loop ratio: half-time, three-quarter, three-halves, and double time. Know exactly what tempo you're bridging to before you activate the loop — no mental math mid-mix. Adjust BPM with tap-to-increment controls or type it directly.

——— MIX PLANNER ——— Enter both decks' tempos and get the exact pitch shift percentage you need, plus a loop bridge grid showing where each ratio lands relative to your target BPM. Tap tempo mode lets you figure out BPM by ear, straight from the music.

——— GENRE TRANSITIONS ——— Curated mixing advice for 15+ genres — House, Drum & Bass, Techno, Hip-Hop, Afrobeats, and more. Pick your outgoing and incoming genre and get specific, actionable tips on tempo math, energy management, and phrasing — written for that exact genre pair, not generic advice.

——— CAMELOT WHEEL ——— Harmonic mixing made visual. Select your current key and instantly see which tracks blend cleanly — same position, one step clockwise, one step counter-clockwise, or relative major/minor. Safe moves and creative jumps are clearly distinguished.

——— BUILT FOR THE BOOTH ——— · True OLED black UI keeps battery drain minimal while screen-on mode keeps your display active · Built-in countdown timer and stopwatch — no need to leave the app · Fully offline — no internet, no account, no login

——— PRO UNLOCK ——— DJ BPM Assistant is free to download — the BPM calculator is fully usable at no cost. A single one-time purchase unlocks everything: Mix Planner, Genre Transitions, the Camelot Wheel, and all loop ratios. Pay once, use forever. No subscription, no recurring charges.
