SiC Tap Tempo is a free, browser-based BPM calculator that finds any song's tempo by tapping — on any key or mouse click on desktop, or with a simple screen tap on mobile. It instantly calculates both the immediate BPM between your last two taps and a running average BPM across your whole session, giving you a fast reading and a stable, accurate one at the same time. Beyond tap tempo detection, it includes a built-in metronome supporting real musical time signatures — from 2/4, 3/4, and 4/4 to compound and odd meters like 5/8, 6/8, 7/8, 9/8, and 11/8 — with an editable BPM field and a looping click that follows the real note-value relationship between quarter notes and eighth notes. No sign-up, no installation, no cost: it runs entirely in the browser as a single self-contained tool for musicians, producers, and songwriters who need to find a song's tempo instantly.
