Frequently Asked Questions
How does BeatMix detect BPM and audio metadata?
BeatMix uses the Soundcharts API to look up audio features for each track in your playlist. It identifies songs by their ISRC code or Apple Music catalog ID, then retrieves detailed metadata including BPM/tempo, energy, danceability, valence, acousticness, instrumentalness, liveness, speechiness, loudness, musical key, genre, and release year.
Can I sort my Apple Music playlist by BPM on iPhone?
Yes! Apple Music on iOS doesn't have a built-in BPM sort, but BeatMix solves this. It syncs your playlists, detects BPM for every track, and lets you filter songs with a dual-thumb BPM range slider or sort them into smart preset mixes based on tempo, energy, and more.
Do I need an Apple Music subscription?
Yes, an active Apple Music subscription is required for in-app playback. You can still sync playlists and view audio metadata without a subscription, but playing tracks requires Apple Music.
What are Preset Mixes?
Preset Mixes are smart filters that automatically group your songs based on audio features. Categories include Workout (Warm-Up, Moderate, Intense, Cool Down), Mood (Happy, Chill, Hype, Focus, Party, Romantic, Melancholy), Activity (Driving, Dinner, Sleep, Study, Morning, Commute, Cooking), and Style (Live, Acoustic, Instrumental, Lo-Fi, Electronic, Orchestral, A Cappella, Raw).
Can I create my own custom mixes?
Yes. You can create custom mix presets with your own filter ranges for BPM, energy, danceability, valence, acousticness, instrumentalness, liveness, speechiness, loudness, genre, and release year. You can also create per-playlist custom groups with unique rules.
How does Heart Rate Play work with Apple Watch?
Heart Rate Play reads your real-time heart rate from your Apple Watch via HealthKit and maps it to one of five zones: Rest, Light, Moderate, Hard, and Peak. Each zone has tailored BPM, energy, and danceability ranges. BeatMix automatically selects and queues songs that match your current zone, with gapless transitions as your heart rate changes. Optional voice announcements speak the zone name when you cross thresholds.
Is BeatMix free?
BeatMix offers a free tier with 100 BPM matches and 3 Heart Rate Play sessions — enough to try all the features. BeatMix Pro unlocks unlimited BPM matches, unlimited HR Play, and the ability to save custom mix presets. Available as a monthly or yearly subscription.
Does BeatMix work with Spotify?
BeatMix currently works exclusively with Apple Music via Apple's MusicKit framework. Spotify support is not available at this time.
Is my music data private?
Yes. BeatMix does not collect any personal information. Your playlist data stays on your device. The only external data transmission is song identifiers sent to look up publicly available audio metadata. No personal or user-specific data is ever transmitted. See our Privacy Policy for full details.
