Questions About the PaceDJ Mobile App
Q: What is the difference between PaceDJ/lite and the full version of PaceDJ?
A: Compared to the lite app, the full version provides an ad-free experience and has a BPM Shifting feature. BPM Shifting alters the BPM of any songs you own saved on your device that are in unprotected formats (i.e. MP3, AAC, etc) without making them sound like “chipmunks.” With BPM shifting, your songs can be used to drive many different exercise paces – greatly expanding the motivational power of your library!
BPM Shifting in PaceDJ is based upon a license of Dirac Time Stretch/Pitch Shift technology (c) 2005-2012 The DSP Dimension/Stephan M. Bernsee.
Q: Generally, how does the app work?
1. PaceDJ scans your music library.
PaceDJ creates mixes using the music on your iPod Touch or iPhone.
2. You set the tempo of your workout; PaceDJ builds you a custom mix.
PaceDJ automatically builds a custom mix, sorting the music on your device by BPM.
3. You have a great workout!
Working out to the beat of your favorite music – all custom-mixed to match your target pace/tempo – is really motivating!
Q: What should I do if I don’t have enough workout music on my device?
A: Go to http://www.pacedj.com, where you can find songs sorted by BPM to match your target running, walking, or cycling pace.

Q: What does “Use BPM Shifting?” mean in settings?
A: If you turn on BPM shifting in Settings, PaceDJ will speed up or slow down the BPMs of the songs you own that are saved on your device (unprotected formats only) to match your target pace/tempo on the main screen. On the main screen, you’ll see the original BPM for the song to the left of the song title with a Metronome icon showing that BPM Shifting is enabled.
Q: When I turn on “BPM Shifting” I can’t hear any music playing when I should. What should I do?
A: Make sure that your iPhone is set to “ring” mode instead of “vibrate.” There is a physical switch on the side of the phone to control this. BPM Shifted songs only play when the iPhone is in ring mode.
Q: I have new songs in my library that are not showing up on my playlist; do I need to refresh or somehow re-load my library? The songs are from another app (Rock My Run) that I downloaded to iTunes and then added to my library. They show up as the library is compiling in the startup phase, but then are missing from the playlist.
A: Rock My Run mixes have unique titles, and are usually mash-ups of popular songs. This unique content does not exist in the Echonest’s database. When Echonest doesn’t have a match, the song shows up as “unmatched” in PaceDJ. You can tap out the BPM for those songs using the drum though!
Q: Is it possible for pacedj to scan the music on my pc so I know what to download onto my phone? I’m trying to save space on my phone by only having those tracks that match my required pace.
A: PaceDJ currently only determines BPMs for the songs saved on your phone. However, if you want to reduce the number of songs to save space on your phone, here is an approach that should work.
- Create a new playlist in your iTunes library on your PC and name it something like “Exercise.”
- Drop any song that you think you would enjoy exercising to into that playlist.
- Sync your new playlist to your iPhone.
- In PaceDJ settings choose the “Exercise” playlist during initial setup (you may have to delete and reinstall the app to do this).
- PaceDJ will determine BPMs for the new playlist and then you are done.
Q: What does the button “Measure your pace” do?
A: This feature will tell you your step rate in steps/minute, which you can use to find songs to match your pace on PaceDJ.com.
- When you press the button, the app will instruct you to walk or run for 30 seconds with your phone in your hand.
- Swing your arms normally as you walk or run, and the app will determine your pace.
- Upload your pace from your phone to PaceDJ.com when finished to find songs that match.
Q: How do I know if PaceDJ is accurately measuring my pace?
A: There are a few things you can doto check for accuracy:
- Be sure to carry your phone in your hand and swing your arms normally when measuring your walking or running pace.
- Also, check your pace against the typical ranges provided at conclusion of pace measurement.
- If you are outside the range, we suggest your re-measure your pace with the pedometer.
- Test your measured pace by walking or running to a song with a similar BPM. If it feels comfortable, then the app measured your pace accurately.
Q: Do I need a profile on PaceDJ.com in order to upload my pace from the app?
A: If you don’t have a profile yet, PaceDJ will prompt you to create one when you upload your pace. If you already have a profile, PaceDJ will ask you to login and then update your target pace within the profile.
Q: After uploading my pace, can I start searching for songs on PaceDJ.com using my phone?
A: Since PaceDJ.com is not yet optimized for mobile, we recommend using your PC to search for songs on PaceDJ.com.
A. In “Settings,” tap “Tempo Range.” You’ll see a roller that allows you set the tempo range between 0-10 BPM.
Q. What do the thumbs up/down icons mean?
A. These icons allow you to tell the app if you like or dislike a song. If you tap “thumbs up,” the app will prioritize that song higher in your playlist. If you tap “thumbs down,” then the app will move that song to the end of your playlist, but won’t erase the song.
Q. What does the small number to the left of the song title mean?
A. This number is the actual BPM of the song you are listening to. This number should be within the tempo range for your Target BPM that you choose in “Settings.”
Q. What does “Fix BPM” mean?
A. Unfortunately, sometimes PaceDJ is provided an incorrect BPM from our online database partner. If you think a song’s BPM is marked incorrectly, then tap “Fix BPM,” and you will be able to correct the BPM by tapping the tempo of the song on a virtual drum that will appear.
Q. What does the lock icon in the top left corner do?
A. If you tap the lock icon, then you will see a locked screen. In some cases, the album artwork for the song you are listening to will appear. The locked screen prevents you from accidentally tapping a button while you are exercising. If you want to unlock, just tap the same icon while in the locked screen and the Main Screen will reappear.
Q. How do I access “Settings?”
A. In the top right corner of the Main Screen, you’ll see a small circle that looks kind of like a gear. Tap that circle, and the Settings page will appear.
Q. What does “Activity Type” mean?
A. If you tap on “Activity Type,” you can tell PaceDJ if you are a walker, runner, or cyclist. Your choice will set the default Target BPM for your activity in the main screen.
Q. What does “1/2 Tempo Songs” and “2x Tempo Songs” mean?
A. If you select these, the app will include songs in your playlist at 1/2 or 2x the Target BPM that you choose. These features can increase the number of songs that the app can choose from, and make your playlists larger.
Q. What does “Tempo Range” mean?
A. This setting allows you to set a range around your Target BPM. For example, if your Target BPM is 130, and if you set the range to +/- 5 BPM, then PaceDJ will include songs in your playlist between 125 – 135 BPM.
Q. What does “Playlist” mean?
A. Here, you can tell PaceDJ what playlist in your device library to use. We suggest using your entire library, so PaceDJ can have the largest possible group of songs to work with.
Q. What does “Manage Music/Fix BPMs” mean?
A. Tapping here allows you to see all of the songs in your libary as well as the BPMs for those songs. If you see a song that has an incorrect BPM marking, then you can tap on that song title and fix the song by tapping on the virtual drum that appears.
Q. What is the drum for?
A. If you need to correct the BPM for a song, use the drum. While listening to the song, tap the beat at least 15 times on the drum. Then tap “Save BPM” in order to update the BPM within PaceDJ.
Questions About the PaceDJ.com Service
Q: What does it cost?
A: You can create a profile, search for songs, and create playlists on PaceDJ for free. If you decide to purchase a song via PaceDJ, you can click through to either iTunes or Amazon.com where you can transact at the price/song charged by those services.
Q: How does PaceDJ.com calculate my target pace?
A: When you create your profile, PaceDJ uses common BPM rates for your activity as a baseline and then suggests a target pace for you, taking into account factors including your age, gender, height, and fitness level. If the initial estimate is a little too fast or slow for you, then you can adjust your target pace within your profile and within the PaceDJ app to fit your needs. Try it out!
Q: Why doesn’t PaceDJ.com recommend songs based on my mile time when running, walking or cycling?
A: People have different stride lengths, influenced in part by age, height, gender, and fitness level. Because people have different stride lengths, and typically don’t measure their stride length, it is difficult to accurately suggest songs that match a person’s desired mile time.
Q: What should I do if I’m not sure about my target pace?
A: You are in control! If you purchase the PaceDJ app, you can determine the BPMs of the songs already on your phone. Once you’ve done that, go test out the app while you exercise and find the right BPM for you.
If you don’t have songs on your phone yet, find a song on PaceDJ.com that you think has the right tempo for you and go for a walk, run, or ride while listening to that song. Match your steps to the tempo. Determine if the song’s tempo feels too fast or slow for you. If it’s a match, then go find more songs around that tempo.
Q: How do I find songs on PaceDJ.com?
A: Songs on PaceDJ are added by users and by PaceDJ. If you don’t find a song in our system, try a “deep search” (you’ll see the link). A deep search usually finds the song you are looking for, which you can then add to your playlists.
Q: How do I add songs to my playlists?
A: Click on the song title, and then “Add to Playlist.”
Q: Can I add songs to more than one playlist?
A: Yes you can. Just click a song title, then “Add to Playlist,” and choose the additional playlist you want to add the song to. Some songs are great for multiple activities. For example, a song with a BPM of 160 is great for running, and the 1/2x tempo of 80 is great for cycling.
Q: Can I create multiple playlists?
A: Yes you can. Build as many as you want!
Q: How do I put playlists or songs on my phone?
A: You can download individual songs via iTunes or Amazon. If you want to buy a whole playlist though, you must do so through iTunes (sorry, but we don’t control this). To buy a playlist, click “Buy This Playlist on iTunes.”
Q: Why is the BPM range so wide for some playlists?
A: Playlists can include songs at 1/2x and 2x of typical BPMs for running, walking, and cycling. Consequently, for a target running BPM of 160, you may also see recommendations for songs at 80BPM (1/2x). In this case, you won’t find songs at 320BPM, since that tempo is outside the typical range of recorded music. Slower BPMs are common for cycling, for example 70BPM. In this case, PaceDJ will present songs at 140BPM (2x) for you to choose from.
Q: Can I view PaceDJ.com on my smartphone?
A: We’ve not yet optimized PaceDJ.com for mobile. That said, you can still view PaceDJ.com on your phone, and can utilize the site just as you would on your PC. You may need to zoom in to see parts though. Also, listening to song samples requires Flash, which is not supported by all smartphones. If your phone doesn’t support Flash, then PaceDJ will allow you to listen to the song sample anyway by linking you through to the song file provided by iTunes.
Q: Can I use PaceDJ for other sports than running, walking, or cycling?
A: PaceDJ should be useful in any sport that has a repetitive cadence such as snowboarding, roller skating, snow skiing, swimming, etc. We plan to add other activities, so stay tuned. If you have suggestions please let us know at firstname.lastname@example.org.
Q: What should I do if I notice that a song has the wrong BPM?
A: If you own the PaceDJ app, you can correct song BPMs by tapping out the tempo on the drum. Tap “fix bpm” in the main screen of the app to correct a song’s BPM.
Q: Can I use other exercise apps at the same time as PaceDJ?
A: Yes, provided you don’t turn on BPM Shifting which is available in the full version. BPM Shifting requires more of your phone’s CPU, so you can’t use another exercise app at the same time. However, if BPM Shifting is off, you can use other exercise applications simultaneously.
Q. How can I provide feedback or report a bug?
A. Please email us at email@example.com, and thanks for giving us the chance to fix the problem!
Q. How many songs should I have in my device library for PaceDJ to work the best?
A. Basically, the more songs you have on your device, the better PaceDJ will work.
- If you have lots of songs that you might enjoy dancing to, then you should have a good library for exercise.
- If your library is mostly classical music or slow/mellow music, then you may have fewer choices that are well-suited for exercise pacing.
Q: What should I do if I have a mix of songs on my device, and some are good for exercising, while others are not?
A: Sometimes you have songs on your device, for example audio books, that aren’t what you want to listen to when exercising. A good way to manage this is to create a playlist entitled “Exercise,” and move all the songs you like for exercise into that playlist. Within the PaceDJ app, you can then select the “Exercise” playlist instead of your entire library. This practice will ensure that PaceDJ avoids songs that you don’t want to listen to during your workouts.
Q. What does “BPM” mean?
A. BPM stands for “Beats Per Minute.” Every song has its own unique tempo, in Beats Per Minute. Songs that are slower, tend to be between 80 – 100 BPM, while songs that are faster tend to be between 140 – 180 BPM.
Q. Why is BPM useful for exercise pacing?
A. When you do any repetitive motion sport (like walking or running) and when you are exercising at a consistent speed, you take a specific number of steps per minute (in cycling, you pedal in rotations per minute – RPM). You can match your steps per minute to the BPM of songs and use the songs to attain your desired exercise pace.
