TrailMix Pro – Run with Music

Resonant Technologies, LLC
TrailMix works almost magically to detect your pace while walking or running and instantly adjusts the music tempo to stay in sync. The result is a music app that “runs” along with you, speeding up or slowing down songs, while maintaining superb audio fidelity without producing the “chipmunk” effect.

“TrailMix is an awesome app to match songs to your tempo.” -iGeeksBlog

◢◤ MIX IT UP ◥◣
The Magic Shuffle feature picks the right song for your current pace 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 pace, 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. Tap along to the tempo to manually set the BPM, or try a handpicked workout playlist that’s ready to use with TrailMix. (Requires iOS 13.0 or later.)

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

You may also choose to set the pace manually and lock in a song at a preset speed. Or play all the tracks in a playlist at a particular tempo for a more consistent workout. This “cruise” functionality is perfect for runners who want to lock in an even pace, such as 180 beats per minute.

▪ Play any song, and its beats mirror your feet, with support for various music sources.

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 pace 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). Music not included.
