ArcX

Patented music matched to your live heart rate and mood. Powered by science.

ArcX is the only fitness app that matches music to your live heart rate and mood in real time. Not recommendations. Not a curated playlist. A patented performance system that evolves with every rep, every stride, every beat.

MUSICBOOST - PERFORMANCE MUSIC, POWERED BY SCIENCE

Your mood sets the tone. Your heart rate writes the rest.

Before your workout, tell MusicBoost how you're feeling, what you're doing and how hard you're going. Connect Spotify, link your wearable and press Play.

From there, MusicBoost reads your live heart rate and adapts your music in real time - turning it up as you push harder and dialling it back as you ease off. No manual adjustments. No skipping tracks. Just the right song, at the right moment, every time.

Research shows tempo-matched music delivers: +15% performance output -12% perceived fatigue +20% training endurance
