\### 🏃‍♂️ What is RunSync?

I am a solo engineer building a utility designed to clear out the friction of finding the right running music. Instead of hunting for pre-made pacing playlists, \*\*RunSync\*\* lets you set a specific, static target cadence (e.g., 175 or 180 BPM). 

The app then looks at your music and automatically filters your audio catalog to serve up tracks that perfectly match your exact target target performance rhythm.

\### 🧪 What I Am Testing

I am looking for 20–50 runners to try an early-stage build on their physical iPhones. Because this build relies on manual cadence entry to sort your audio, the core focus of this test flight is checking:

1. Core MusicKit API loading and playlist filtering speeds.

2. Background audio playback stability while you run.

3. Proper entitlement mapping through the paywall engine.

\### 🎁 The Tester Bounty

Because this is running through the Apple Sandbox ecosystem, \*\*all premium/Pro in-app subscriptions are 100% free\*\* while testing. 

If you use the app on a workout and submit a quick line of feedback or a bug report via the TestFlight portal, \*\*I will permanently hardcode your User ID for a lifetime free Pro entitlement\*\* once the application goes live on the App Store.
