What's the best Android app for quick directional checks without draining battery?

Compass is a straightforward tool designed for users who need reliable directional information without the battery-intensive processes of full GPS apps. It excels in scenarios like hiking, urban navigation, or quick orientation checks where internet access is spotty or power conservation is key. The app utilizes the phone's built-in magnetic sensor to provide real-time compass readings, and it includes a calibration feature to improve accuracy. Users appreciate the declination adjustment option, which accounts for magnetic variation based on location, enhancing precision for activities like map reading or setting up a campsite. Reviews indicate that the interface is clean and uncluttered, allowing for instant access to cardinal directions without distracting ads or complex menus. However, some feedback notes that accuracy can vary depending on the device's hardware quality, and it may not replace a dedicated physical compass in highly magnetic environments. For everyday use, though, it strikes a balance between functionality and efficiency, making it a dependable choice for quick bearings.
