TrekBurn: Hiking Calorie & BMR

TrekBurn is the ultimate offline hiking calorie tracker and calorie deficit calculator designed specifically for mountain hikers, backpackers, and outdoor enthusiasts embarking on multi-day treks. Calculate your baseline BMR, track energy expenditure, and manage your caloric balance entirely offline in the wild.

🔋 UNMATCHED BATTERY EFFICIENCY
Traditional fitness tracker apps drain your phone's battery in hours by constantly polling GPS sensors. TrekBurn solves this by relying on highly optimized, passive background data aggregation. By integrating seamlessly with Health Connect, TrekBurn reads aggregated steps, active calories burned, and elevation metrics already collected on your device. This means zero continuous GPS polling by TrekBurn, keeping your phone alive for multi-day wilderness expeditions.

🏔️ OFFLINE-FIRST ARCHITECTURE
In the deep backcountry, network connections are non-existent. TrekBurn is built from the ground up to operate in 100% offline environments as an offline calorie counter. With zero internet permission requests in its Android Manifest, the app is physically incapable of transmitting data. All your baseline settings, daily trek summaries, and energy logs are stored locally on your device in a high-performance Room Database.

🔒 ABSOLUTE PRIVACY & SECURITY
Your fitness and biometric data belong to you, and only you. Because TrekBurn uses zero external servers, cloud databases, or tracking SDKs, your data never leaves your device. Rest easy knowing your location history, weight, and calorie burn metrics are completely safe from data breaches and third-party advertising tracking.

🌙 OLED PITCH-BLACK THEME
Optimized for the trail and night usage, TrekBurn features a stunning, premium OLED pitch-black theme. The high-contrast visual design guarantees outstanding readability in direct sunlight while minimizing display power consumption on OLED screens.
