A New iPhone/iPod Running App: PaceDJ

San Diego, CA, June 30, 2011 – Pacing Technologies, LLC today, June 30, 2011, launched PaceDJ, a music application for iPhone and iPod Touch, which helps runners, walkers, and cyclists attain breakthrough fitness results by creating music mixes that help users synchronize their feet with the music they love.
PaceDJ works by determining the tempo of each song that is saved on a user’s iPhone or iPod Touch, based on its beats per minute (BPM). The app then allows the user to set his or her target exercise pace, either in steps or rotations per minute. Next, the app creates customized pacing playlists drawn from the user’s iPhone or iPod Touch music library. The clincher is that these mixes are comprised of songs with BPMs that closely match the user’s target exercise pace. Ultimately, the user naturally synchronizes his or her steps with the song’s tempo. This can help runners, walkers, and cyclists maintain an optimum pace, while also being a powerful source of motivation.
We have 5 codes to download the app for free. Just comment this article on why you think this app could be a good idea – the first five commenters will receive a free download code (remember to add your email. It won’t be published on the website and it will ONLY be used for this contest). Comments are moderated and won’t appear immediately, but once approved, the timestamp on the comment will clearly indicate when the comment was submitted.
When users first set up PaceDJ, the app instructs them to select their activity type (whether running, walking, or cycling). The app then uses the activity type to estimate the user’s correct BPM. Next, the app delivers an initial music mix, drawn from the music on their iPhone or iPod, which is based on this pacing. After this setup process, users can easily increase or decrease the target pace, which then updates the music mix to meet the new target exercise pace.
PaceDJ also offers special features that make the app extremely user-friendly. For one, the app prioritizes songs in mixes according to users’ preferences, based on whether users “like” or “dislike” songs they hear in the mix. Additionally, the app selects songs based upon an energy ranking, which deprioritizes lower energy songs unless a user “likes” them.
Finally, PaceDJ allows users to include songs at half the tempo and twice the tempo of their target exercise pace. This feature expands the number of songs that the app can choose from, which increases the variety of music mixes.
A note from the author: for best results, it is good if you have a few hundred songs saved on your iPhone or iPod Touch. I personally have about 800 songs on my device, which works very well in terms of the variety of music I hear in my mixes.
