Your Smart Step Counter & Fitness Guardian
Fit Sentinel is an Android app that helps users stay active and safe by accurately counting steps using both Accelerometer & Gyroscope or the device’s built-in Pedometer, depending on availability. Built with Kotlin and Jetpack Compose, the app offers a sleek and modern UI for step tracking, activity history, and optional safety features.
