This is a great app. I never use the built in player anymore. My random playlists are mixed so well with the tempo matching feature. Thanks for making this!

This app makes me Run faster and farther. Awesome app

Does magic with the songs Great for long runs

I dont know whether its because Im using it in an iphone 4, but it keep crashing in the beginning of the songs...

I didn't believe it would work until I tried it and it works efficiently. Good app for jogging/running.

Keep u on your toes in how real about oneself3⃣

I'm using the "couch to 5k" training routine where you alternate walking & running, and trailmix is the PERFECT companion app. Whether I'm walking or running, my music is always at the right speed to accompany me and boost my energy. I love trailmix. Show more

This app is perfect for my treadmill workouts. Sometimes it takes a few seconds to adjust to the proper timing, but it is great to have music that keeps time with my steps instead of me having to find music that syncs with my workout! Show more

I love this app. Hearing my favorite songs speed up to match my workout speed or to slowdown for my cool down is such a motivation. I live having the beats sync with me and thus I tend to work out longer. This app is a must have. Show more

It just speeds up or slows down the song to your heart rate so it makes the songs so horrible. It is a terrible app. If I could not give a star, I would. Show more

BEST APP EVER. GET THIS APP WHILE YOU CAN!

Really helps keep up a steady pace. Love it!

This works well. Play any of your favorite music and it will speed up or slow down to your pace. Great for making movement and exercise more enjoyable.

This is the first time that i would rate an app for iPhone. It serves it purpose. You walk, you jog or run, the beat of the music will just follow you and make your cardio run easier because you don't need to follow the beat of the music, the tempo will just suit you whatever your speed. If i can rate this more than 5 star, i will do it. Thanks. Long time for me to find this kind of app for runner enthusiast like me. Show more

In the website, you learn how to set "cruise" at whatever pace you want, say like 180 BPM. You just touch the indicator and move it to the pace desired. To reset it to follow your current pace, touch the center of the dial. I'm looking forward to music instead of a metronome beating! Show more

This is by far the best running/pace app I've found thus far and well worth paying for. It will either find music to go with your pace or (my favorite) increase the beat of your music to set the pace you want to run. It's easier to use than other apps with similar goals and it works. That said, it has recently been crashing on me. It can go well for half an hour to an hour OR it can crash four or five times in that period. It stops moving from song to song and doesn't respond if you try to move to the next song manually. If you close and re-open the app, you just get a black screen with three small dots in the middle (it seems to be trying to load, but doesn't.). The. Only solution I've found is to totally shut down and restart my iPhone, which I don't want to have to do repeatedly on a run . Please fix this! I love this app and want it to work well. Show more

Works great. Been looking for an app that changes the beat to match my stride rate. This one both changes the beat automatically, and can be set to a target BPM. Listen to ALL your music again when you run!! Show more

I use this app every time I run. I didn't give it a 5 because it doesn't integrate with iRunner (or other fitness apps) very well.

I didn't like this app. If you really enjoy your music, hearing it at a different beats per minute (BPM) than it was originally recorded is irritating. I would prefer an app that allows you to set the BPM that you walk or run at and the app searches your library for songs that play at or within a few BPM's of that timing. It would sound better and help you keep a certain pace. This app slows down or speeds up with your pace but doesn't motivate you to stay at a set pace. Show more

I was a little skeptical at first, but this app works fantastically. When I moved from the treadmill to running outside, it was hard to not run too fast to unconsciously match the beat of my music. This app helps me run at my own pace and still feel in sync. Show more
