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.

RoundDanceQ
Read full descriptionHide full description
RoundDanceQ is a music and video player built specifically for round dance practice. "That move, one more time" — the Q button brings that exact moment back with a single tap, and it will change the way you practice. ■ Q Button & Remember Q — the heart of the app While playing a video, just tap the Q button to remember that exact point. Next time, simply tap the flower marker on the timeline to jump straight back to that spot and start a loop. Never miss the moment you want to see "just one more time" — repeat it as many times as you need. ■ Sections & Loop Practice Section marks visualize the structure of a song. Combine section-based looping with A/B loops to focus on the parts you find difficult. Pre-roll (starting playback before the count) and beep cues help your body learn exactly where the loop begins. ■ PDF Cue Sheets & AI Analysis Practice while viewing your PDF cue sheet. With the AI analysis feature (requires your own AI service API key), the app can automatically read a PDF cue sheet and fill in section information for you. ■ BGM Mode Play your practice songs continuously by folder. Use shuffle, repeat-all, and the cue/original filter to recreate the atmosphere of a lesson hall. ■ Library Management Cued and original versions of the same song are automatically grouped together. Manage links to your NAS or streaming service, and export your library as a two-column PDF. ■ Apple Watch, Lock Screen & Pocket-Size Remote Control Jump between sections and control playback right from your Apple Watch — or from a tiny Bluetooth remote small enough to fit in your pocket (works great with keyboard-mode controllers like the 8BitDo Micro), so you can control the app hands-free while you dance. Full playback control, including the seek bar, is also available from the Lock Screen and CarPlay. ■ Backup & Sharing Create a complete ZIP backup including your songs, videos, PDFs, and metadata. Sharing via AirDrop is also supported. ■ Cuer Mode (Pro) A "cue karaoke" that shows and records the current cue in sync with playback — practice calling cues in your own voice. The current cue also appears on your Apple Watch and Lock Screen. ■ RoundDanceQ Pro (one-time purchase) Unlocks Cuer mode and AI features (cue sheet analysis, note generation). Pay once, use forever — not a subscription. * Existing users keep Pro features free — thank you for your support! * AI features require your own AI service API key (Cuer mode works without one).
