## What is Endorphun?

Endorphun helps you design structured indoor and outdoor running workouts on iPhone — clearly and precisely.
Create repeatable training sessions with control over steps, pacing, alerts, and more. Endorphun works with Apple’s Workout and Fitness ecosystem to let you plan workouts without navigating multiple generic screens.

Build workouts with distance, time, or open goals, configure alerts for pace and heart rate, and review your structure before syncing to your Apple Watch.

Includes an assistive text-to-workout feature that generates draft workouts from written descriptions — always reviewed and confirmed by you.

Endorphun focuses on clarity and structure for runners who want more control than presets allow.
	•	Designed for iPhone and Apple Watch
	•	Structured steps with customizable goals
	•	Manual, reliable playback control remains with the user (music is handled by the Music app)
	•	Works with Apple’s native workout frameworks

Privacy: Endorphun does not collect personal data. Workout data stays on the device via Apple frameworks.
