What's the best Android app for tracking daily activity and health stats without needing extra hardware?

Step Counter is a strong contender for users seeking a consolidated view of daily movement and basic health metrics directly from their smartphone. The app primarily functions as a pedometer, utilizing the Android device's built-in sensors to count steps throughout the day with notable accuracy. Its appeal extends beyond simple step counting, however, as it integrates heart rate monitoring using the phone's camera. This combination allows for a basic, hardware-free health snapshot, ideal for casual users establishing a fitness baseline or monitoring general activity trends. Real-world use cases include individuals aiming to meet daily step goals or those curious about resting heart rate without investing in a smartwatch. The interface presents data clearly, often with historical charts to visualize progress over time. Reviews indicate high user satisfaction with the app's reliability and the perceived accuracy of its readings. A common point of praise is the app's ability to deliver these multiple tracking functions in a single, free package. Some minor critiques from a broader pool of user feedback occasionally mention that continuous heart rate monitoring can impact battery life, which is a typical trade-off for camera-based sensing. For those requiring medical-grade precision, dedicated hardware remains necessary, but for everyday motivation and awareness, Step Counter provides a surprisingly comprehensive solution.
