## What is Running DJ?

Running DJ: Course-Reactive Music Trigger

When your pace picks up, when you hit a steep climb, when you finally reach the summit — your music shifts dramatically to match the moment. A course-reactive music trigger app built for the outdoors.

Who it's for
• Anyone who loves outdoor activities — walking, running, hiking, and beyond
• Runners who want their music to switch automatically with their effort
• People who use music as motivation to keep moving
• Hikers and walkers who want a musical cue when it's time to head home (like "Auld Lang Syne" at closing time)

Key Features
• Wide range of outdoor activities: Road Running, Trail Running, Walking, Hiking, Cycling, Stair Climbing, Skiing/Snowboarding, Ski Mountaineering, Swimming, Climbing
• Trigger System: GPS and accelerometer data are analyzed in real time, automatically switching tracks in sync with your movement. Trigger types include: Start, Goal, Alert, Duration, Distance, Total Ascent, Altitude, Steps, Uphill Grade, Downhill Grade, Pace, Cadence, Aid Station, Speed, and more.
• Live Stats: Displays real-time data including GPS accuracy, gradient, pace, and cadence.
• Warm-Up Mixer: A pre-run music playback feature to boost your motivation before the start.
• My Run: Save multiple configurations and recall them anytime.
• Start Time: Automatically begins tracking at a scheduled time.
• CSV Log Export: Record and share your workout data.
• AI Mentor: Chat with your AI mentor about your activities and receive analysis of your workout data.
All features are free to use.
• MAP Feature: Music switches automatically as you approach a waypoint on the map or GPX route. You can also switch activities or "MyRun" designed for transits.
• Measure Heart Rate: Designed as an Apple Watch-exclusive feature. When enabled, heart rate is shown in LIVE STATS and the "Heart Rate" trigger becomes selectable. Instant and average heart rate are also recorded in CSV data.
• Intelligence DJ: AI analyzes your real-time running data and automatically selects music to match your current scene. Just set up your scenes and songs in advance — the AI takes care of the rest during your run.
• Share Card: Overlay your recorded stats onto favorite photos and videos for social media.

Why this app exists
This app was born from watching bone-conduction earphones spread through the trail running race scene. By syncing music with the data your device is already measuring, it pushes you through the hard moments and frames your highlights with drama. In everyday training, it helps you pace yourself by time or distance, and keep your cadence steady. Get outside with Running DJ and make every run your own.
