We took a music player, combined it with a state-of-the-art beat analyzer, dynamic gait detector, and high fidelity audio time stretcher, then hid all the advanced technology under the hood. The result is magical: a simple, easy-to-use music player that can change the beat of any song to match your footsteps automatically.
Awesome idea. Exceptional execution. And a great user interface. Completely worth the price and highly recommended. (iTunes review)
How it Works
- You pick a song to start off with, and in seconds, TrailMix will have determined its exact tempo
- The pace of your footsteps is automatically detected using the accelerometer sensor built into your device
- TrailMix remixes the song to match your current pace by making the tempo faster or slower as necessary

Amazingly Fun to Use
TrailMix is for everyone, not just workout enthusiasts, because it makes even a casual walk into a delightful experience. Step in sync with the music and brighten your day as you:
- walk to school or work
- stroll to a nearby store or restaurant
- explore a park or beach
Upgrade Your Workout
Of course if you do work out, then TrailMix will take your workout to a whole new level. You’ll experience a rush as you move with the music that lets you break through the mental barrier and perform at your physical peak. According to scientific research, “synchronizing movements with music enables athletes to perform more efficiently, resulting in greater endurance.”

Although TrailMix includes an automatic pace detector that works in your pocket or armband, it’s also possible to set the pace manually. This allows you to work out at a single consistent pace with your mobile device placed anywhere on your person.
It Just Works
Our remarkably sensitive pace detector works with the device in either a pocket or armband, regardless of whether you’re running, strolling, or using an elliptical machine or treadmill. And if you speed up or slow down, TrailMix will instantly change the tempo of your music without changing the pitch, making it sound like your songs were originally produced at whatever your current pace happens to be.
TrailMix works without any setup or desktop application thanks to the built-in tempo analyzer that finds the BPM of virtually any song within seconds. We custom-designed our algorithm exclusively for TrailMix for ultra-fast yet incredibly reliable analysis that blows away the competition.

TrailMix was featured in the Seattle Times blog on January 16, 2013 with an article by Mónica Guzmán.
Brothers James and Tom Potter, originally from Issaquah, have created an app called TrailMix that makes the songs on your iPhone or iPod match the tempo of your run or jog. Select a playlist through the app and it will automatically find tracks that match the speed of your steps. Play individual tracks and it will speed up or slow down the songs according to your rhythm.
