BPM Finder: Song Key & Tempo

Find the BPM and the musical key of a song in seconds. Hold your phone near the speaker and tap Listen, or open an audio file from your phone. BPM Finder works out the tempo and the key on your phone, offline, with no ads. WHAT YOU GET • Tempo in BPM, shown to one decimal place • Key and Camelot code (for example F minor · 4A), plus the relative major or minor • Half-time and double-time readings when a song can be counted more than one way • Tap tempo: tap along with the beat to count BPM by hand • Camelot wheel: tap any key to see which keys mix well with it, for DJ harmonic mixing • History of your results, saved automatically on your phone LISTEN OR OPEN A FILE • Live: the app listens through the microphone for about 20 seconds. The first reading appears after about 8 seconds and keeps refining. • Files: MP3, M4A, WAV, FLAC, OGG and the sound of videos. Long DJ mixes are analysed from a 2-minute window in the middle, and the app tells you which part it used. HONEST RESULTS Tempo and key are estimates. Music can be felt at half or double time, and many songs fit both a key and its relative major or minor. When BPM Finder isn't sure, it says so and shows the other likely readings instead of one flat answer. Trust your ears when they disagree. PRIVATE BY DESIGN • Sound is analysed on your phone and deleted right after. Nothing is uploaded. • No account, no ads, no tracking. • The microphone is used only while you tap Listen. FREE AND PRO • Free: 3 song analyses to try it (live or file). Tap tempo and the Camelot wheel are always free. • Pro: unlimited song analyses, your full history and CSV export.
