TrailMix is a unique combination of three powerful tools: a running cadence tracker, a step-synchronized music player, and a metronome. It’s an all-in-one app that includes tools to check your running cadence, change the tempo of any song in your library to match your stride, and play a beat to help guide you to the perfect cadence. The Pro version features Magic Shuffle with intelligent tuning modes, the Average Cadence stats module, and a customizable cadence range. • While you’re walking, jogging, or running, the cadence tracker detects the speed you are moving at, in steps per minute. • TrailMix is the music lover’s choice: the original step-synchronized music player, it can increase or decrease the tempo of any song without distortion, and it works with your existing music library. • The metronome is state-of-the-art, with physically modeled drums, a subtle reverb effect, and evolving musical chords. ◢◤ FEATURES ◥◣ • A cadence monitor displays your current steps per minute. • Easily increase or decrease the tempo of music or a metronome to help pace your run. • Synchronize your music to match your cadence. • Works at any speed: walk, run, sprint, or stroll. • Play songs from your existing music library. • Superb audio quality and no “chipmunk” effect. • Switch between automatic and manual cadence. • Beautifully crafted, incredibly intuitive interface. • Built-in pedometer & timer functions. • Health app integration for steps and workouts. • Compatible with Apple Music. ◢◤ PRO FEATURES ◥◣ • Magic Shuffle finds songs close to your cadence. • TrailMix Pro also includes three customizable tuning modes for Magic Shuffle. • The stats screen displays “Average Cadence” information. • Customizable cadence range with Standard (80–180 BPM) and Extended (40–240 BPM) presets, plus a fully custom range option. The Magic Shuffle feature picks the right song for your current cadence whenever you go to the next track. Customize Magic Shuffle to match your workout style with three unique tuning modes. The best match option picks the song closest to your stride rate, variety mode adds a bit of randomness, and tempo boost aims for tracks slightly below your cadence and speeds them up. ◢◤ RUN WITH MUSIC ◥◣ For downloaded songs that you have purchased or imported, the app features automatic beat detection that works on-device. TrailMix works with all the music on your device, in any musical genre, not just traditional workout songs. Our advanced recognition engine “listens” to the music to sync the perfect tempo. Accurate and efficient, it detects the beat of any song within seconds. For other songs, such as those streaming from Apple Music, just tap along to the tempo to manually set the BPM. TrailMix can detect your steps and make the song faster or slower to match your cadence, returning to the song’s actual speed in an instant when you stop moving. TrailMix also lets you set the playback tempo and lock in a song, or even an entire playlist, at a particular speed. This constant tempo functionality is perfect for runners who want to lock in a consistent stride rate, such as 180 beats per minute. ▪ Play any song, and its beats mirror your feet. ◢◤ UPGRADE YOUR WORKOUT ◥◣ According to scientific research, “synchronizing movements with music enables athletes to perform more efficiently, resulting in greater endurance.” (Karageorghis & Priest, 2008, The Sport Journal). Automatic cadence detection works anywhere, from the trail to the treadmill. ▪ Research suggests that moving to the rhythm can help your body perform more efficiently — so you can go further with less effort. ____________________________________________ AUDIO COMPATIBILITY: Works with all standard audio files (MP3, ALAC, AIFF, WAV, and AAC). TrailMix does not include full-length songs. LEARN MORE: Visit us at trailmixapp.com Apple Music is a trademark of Apple Inc.

Verdict
The clearest difference is price: PaceGrid at Free against TrailMix Pro's $11.99. PaceGrid also leads on rating (5.0 vs 4.3) and update cadence (every 5 days vs every 3 weeks). TrailMix Pro's advantage is in-app purchases (none vs 1) and chart position (#197 vs unranked). On ads, monetization model, device support and iOS requirement there is nothing between them.
