🧠 Core Algorithms

Athlene performs all calculations directly on the user's device without relying on cloud processing.

Distance Calculation

• Haversine Formula
• Great-circle distance computation using GPS coordinates

Calorie Estimation

• Metabolic Equivalent of Task (MET)
• Activity-based calorie estimation

Tracking Logic

• Custom interval-based location recording
• Automatic daily statistics reset
• Singleton Location Service for efficient GPS management

---

📍 Designed for Offline Use

Athlene is intended for users who exercise in environments where internet connectivity is unreliable.

Examples include:

• Hiking
• Trekking
• Nature trails
• Hill stations
• Rural environments

Since every calculation is performed locally, the application remains fully functional even without cellular data or Wi-Fi.
