MyFitnessDJ is a free iPhone app developed by David Norfleet-Vilaro that allows users to enhance their fitness class profiles by attaching coaching cues to their favorite playlists. With this app, users can create a MyFitnessDJ playlist by selecting tracks from their Music library, including Apple Music tracks, or by choosing an existing playlist.

Once the tracks are selected, users can choose from a variety of Smart Presets or enter custom cues to be displayed at specific times during track play. The app also offers the option to select custom begin/end times and crossfade to create a smooth mix using the best parts of each track. To keep track of time, MyFitnessDJ provides an automatic countdown timer to make every second count.

Users can easily share their playlists via AirDrop, iMessage, or email. Additionally, the app offers the unique feature of displaying working zone colors on a HomeKit enabled light bulb by turning on Zone Glow in tools.

For users looking for advanced features, MyFitnessDJ offers two in-app subscription options. The Power Pack subscription ($2.99 per month) includes TickerTape, Cue Lookahead, and Magic Remote. The Studio Edition subscription ($6.99 per month) provides Tempo Tools and MyFitnessDJ Scoreboard, allowing users to calculate and display working zones from up to 8 Bluetooth devices or up to 60 ANT+ power or heart rate sensors.

Both the Power Pack and Studio Edition subscriptions are auto-renewable and will renew each month unless turned off at least 24 hours before the end of the current period. Payment will be charged to the user's iTunes Account at confirmation of purchase. Subscriptions can be managed by the user and auto-renewal can be turned off in the user's Account Settings.

MyFitnessDJ also offers the option for a free trial period, and any unused portion of the trial period will be forfeited when the user purchases a subscription to the feature set.
