TrailMix is a unique combination of three powerful tools: a running cadence tracker, a step-synchronized music player, and a metronome. It’s an all-in-one app that includes tools to check your running cadence, change the tempo of any song in your library to match your stride, and play a beat to help guide you to the perfect cadence. The Pro version includes the flagship Magic Shuffle feature that finds songs near your cadence, the Average Cadence metric, and the option to choose either 180 or 240 as the speed limit.

• While you’re walking, jogging, or running, the cadence tracker detects the speed you are moving at, in steps per minute.
• TrailMix is the music lover’s choice: the original step-synchronized music player, it can increase or decrease the tempo of any song without distortion, and it works with your existing music library.
• The metronome is state-of-the-art, with physically modeled drums, a subtle reverb effect, and evolving musical chords.

• A cadence monitor displays your current steps per minute.
• Easily increase or decrease the tempo of music or a metronome to help pace your run.
• Synchronize your music to match your cadence.
• Works at any speed: walk, run, sprint, or stroll.
• Play songs from your existing music library.
• Superb audio quality and no “chipmunk” effect.
• Switch between automatic and manual cadence.
• Beautifully crafted, incredibly intuitive interface.
• Built-in pedometer & timer functions.
• Health app integration for steps and workouts.
• Integrates with the Apple Music streaming service.

• Magic Shuffle finds songs close to your cadence.
• TrailMix Pro also includes three customizable tuning modes for Magic Shuffle.
• The stats screen displays “Average Cadence” information.
• Your choice of either 180 or 240 as the speed limit.

The Magic Shuffle feature picks the right song for your current cadence whenever you go to the next track. Customize Magic Shuffle to match your workout style with three unique tuning modes. The best match option picks the song closest to your stride rate, variety mode adds a bit of randomness, and tempo boost aims for tracks slightly below your cadence and speeds them up.

For downloaded songs that you have purchased or imported, the app features automatic beat detection that works on-device. TrailMix works with all the music on your device, in any musical genre, not just traditional workout songs. Our advanced recognition engine “listens” to the music to sync the perfect tempo. Accurate and efficient, it detects the beat of any song within seconds.

For Apple Music subscribers, we also offer a simple yet powerful experience that works well with streaming. Just tap along to the tempo to manually set the BPM. (Requires iOS 13.0 or later.)

TrailMix can detect your steps and make the song faster or slower to match your cadence, returning to the song’s actual speed in an instant when you stop moving.

TrailMix also lets you set the playback tempo and lock in a song, or even an entire playlist, at a particular speed. This “cruise” functionality is perfect for runners who want to lock in a consistent stride rate, such as 180 beats per minute.

▪ Play any song, and its beats mirror your feet.

According to scientific research, “synchronizing movements with music enables athletes to perform more efficiently, resulting in greater endurance.” (Karageorghis & Priest, 2008, The Sport Journal). Automatic cadence detection works anywhere, from the trail to the treadmill.

▪ Moving to the rhythm makes your body more efficient. Fatigue slower, become faster, go further.


AUDIO COMPATIBILITY: Works with all standard audio files (MP3, ALAC, AIFF, WAV, and AAC). TrailMix does not include full-length songs.

Juste parfait! Exactement ce que je cherchais

Cette app mérite d’être plus connue! Elle ajuste le rythme de tes chansons à ton rythme de course. Plus besoin de chercher des musiques qui ont le même beat que toi et que tu aimes! Simple d’utilisation et juste parfait pour garder l’énergie et le rythme avec les musiques que tu adores! Version payante pour accès illimité à vos playlists et 1 seul paiement à vie! Ça vaut le coup.
Prochain step peut être rendre accessible notre biblio Spotify directement.
