Walking or running to iPhone music

Filed under: Computer tips, Gadgets, Sport — chriscroft @ 12:34 pm

I finally got something I’ve wanted for years – music at the right speed on my iPhone.

1 – Download Mixmeister (free) onto your PC and use it to scan all your music and put a BPM number onto every track on iTunes. Very simple little bit of software, obvious how it works.
Until now I’ve been using this to make playlists on my ipod, so for example I have a walking playlist of music that is from 115 to 125 BPM.
For running it’s about 90bpm, so you’d want a playlist of maybe 85-95bpm songs since you won’t have enough songs that are at exactly 90, or whatever your exact ideal cadence is.
If you were keen you could sort them into order with maybe a gradually increasing cadence, or a rush at the end.
But a much better solution is……
2 – Buy Cadence Run DJ for £1.50 and tell it to use all your music. Worked immediately.

So now I can slide a slider in the Cadence app to any speed I want and it will select music from my collection that is at that speed. If I want to speed up or slow down slightly I just slide the slider. Brilliant!



  1. What the world needs now is an iPod Touch Nano that will run this stuff but not be so bulky to carry as an iPhone.

    • yes, agreed – a subset of the genius function

  2. Yes, you are right. i was thinking of an iPod Nano running Apps, but what they should do is subsume the right Apps into iTunes. I have always thought the Genius function was slightly under-powered (if I have give a song one star, that’s because I don’t like it, Genius!). So one enhancement is a Genius function that doesn’t play stuff I have told iTunes I don’t like; another, as you suggest, is a tweak that allows you to ask it for songs that are alike in rhythmy stylee.

  3. Mmm. I downloaded Cadence Run DJ. It crashes if I try to scan my whole library. If I scan playlist-by-playlist, it seems to lose track of songs it already scanned earlier. (But there is no way to keep track of a list of the songs that have been scanned). When it crashes, it keeps on playing and it’s hard work to shut it up. The idea is a good one, but not good enough to engage my patience beyond the twenty minutes I’ve already given it.

    It’s hard to understand what a good interface iTunes is until you try out the efforts of amateurs. (Have you tried Air Cassette?)

    • I only have about a gig of music on my iPhone and it worked fine, so maybe a decent library is too much for it?

    • not heard of air cassette

      • Air cassette is a pretty little app that makes your iPhone look exactly like a Walkman playing a cassette. Nice for when you want to listen to 1970s music. The aesthetics are great, but I never mastered “MixTapes” which are the equivalent of playlists. And it is oblivious to iTune playlists. It was all a bit clunky, and I don’t use it.
