WHY YOU'LL LOVE IT • Zero tapping — the BPM just appears, and keeps updating live. • Real-time accuracy — watch the number lock in within seconds. • Made for how you work — DJs, producers, drummers, dancers, fitness instructors, and curious listeners. FEATURES • Automatic BPM detection — read the live tempo of any music or instrument, hands-free. • Shazam built in — grab the song title and artist while you read its BPM. • Apple Watch app — see the tempo right on your wrist. • Detection history — every reading saved with timestamp, track info, and BPM. Perfect for sets, rehearsals, and crate-digging. • Fullscreen mode — huge, high-contrast numbers you can read across the room. • Variation graph — see how steady the tempo holds, beat for beat.

Verdict

The call

The clearest difference is price: BPM Detector at Free against Synth Modes's $3.99. BPM Detector also leads on update cadence (every 3 days vs every 4 weeks) and rating (4.3 vs 4.0). Synth Modes's advantage is in-app purchases (none vs 13) and ads (none vs shown). On review sentiment and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

BPM Detector holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: BPM Detector has 266 ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 64% of Synth Modes's written reviews are positive against 61% of BPM Detector's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Synth Modes ships an update every 4 weeks, BPM Detector every 3 days. Both last shipped on October 24, 2026.
