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.

Verdict
The clearest difference is ads: Running DJ at none against PaceLog Run's shown. Running DJ also leads on update cadence (every 2 days vs every 3 weeks). PaceLog Run's advantage is iOS requirement (18.5 vs 26.2). On price, in-app purchases and device support there is nothing between them.
