About this app

METRA is the high-precision BPM tapper built by musicians, for musicians.

We know that in the studio or on stage, "close enough" isn't good enough. That’s why we built METRA: a professional-grade tempo tracker that prioritizes rhythmic stability and statistical accuracy over everything else.

Wrapped in a sleek glassmorphism aesthetic, METRA provides more than just a number. Our custom engine analyzes every tap, providing a real-time Accuracy HUD (Standard Deviation & % Accuracy) so you can catch the exact pocket of any groove with confidence.

PRO-LEVEL FEATURES:
• Studio-Grade Engine: Rolling average analysis for high-precision stability.
• Metronome: follow your tapping session with sound, haptics and visual cues.
• Accuracy HUD: Real-time visual feedback on your rhythmic consistency (± ms).
• Intelligent Inactivity Detection: Measurement auto-finalizes after 2 seconds.
• Modern Aesthetic: Dark-mode glassmorphism with smooth reactive animations.
• Persistent History: The latest 20 measurements are stored locally for quick reference.
• Global Reach: Fully localized into 12 languages.

Whether you're dialing in a delay, checking a drummer's pocket, or mapping out a film score, METRA is the professional tool you can trust.
