Sensify is an all-in-one sensor toolkit that maximizes the potential of your Android device's hardware. It goes beyond simple utilities by providing a visually stunning Neo-Glassmorphism UI and a robust architectural foundation built with modern Android trends.
- Aesthetic Excellence: Designed with a premium "Neo-Glassmorphism" language, ensuring a modern look that feels like a flagship experience.
- Hardware Optimization: Intelligently polls device sensors and implements Graceful Degradation for devices lacking specific hardware.
- Real-time Interaction: High-performance data visualization at near 60fps with haptic feedback for a tactile, physical user experience.
- Compass & Altimeter: Uses
TYPE_ROTATION_VECTORfor high-precision orientation andTYPE_PRESSUREfor accurate sea-level altitude calculations. - Bubble Level & Protractor: Leverages the accelerometer for precise leveling. The Protractor features a camera overlay with circular guides and a 'Zeroing' function for relative angle measurement.
- Sound Meter (Decibel): Real-time analysis of microphone input. Displays a time-axis based dB waveform instead of just basic FFT graphs. Includes a vibration alert when noise exceeds 85dB.
- Metal Detector: Utilizes the magnetometer to detect electromagnetic fields. Features real-time graph visualization and haptic intensity feedback.
- Light & Color Meter: Measures ambient lux and uses CameraX to analyze real-time RGB values and color codes from the environment.
- Heart Rate Monitor: Uses CameraX to detect blood flow changes (PPG) in your fingertip. Unlike many apps, it features a Continuous Measurement Mode and records periodic BPM snapshots into history.
- Pedometer: Efficiently tracks steps using
TYPE_STEP_COUNTER(system-level) ensuring minimal battery drain even in the background.
- WiFi/Bluetooth Analyzer: Scans and visualizes signal strength (RSSI), security protocols (WPA3/BLE), and detailed device information.
- NFC Reader: Supports various standards including ISO-14443A and interprets NDEF messages in real-time.
- Deep Info: Detailed monitoring of battery health, hardware specifications, and sensor availability status.
Upon the first launch, Sensify performs a full scan of the device's hardware sensors via SensorManager.
- Results are cached in
SharedPreferencesfor subsequent lightning-fast startups. - The UI automatically filters out tools that require sensors not present in the device.
The back-end consists of a SensorDataManager that wraps standard Android sensor listeners into Coroutine Flow.
ViewModels collect these flows, perform unit conversions/filtering, and emit a cleanUI State.- This ensures thread safety and high performance across all tool screens.
- Dynamic Mesh Background: Driven by a custom
Canvasimplementation that animates circles and blurs dynamically without creating unnecessary objects every frame. - Unified Gauges: Consistent use of
NeonBarGaugeandNeonCircularGaugefor professional-grade visualization.
- UI: Jetpack Compose (Functional UI, Declarative Animations)
- Architecture: MVVM + Clean Architecture
- D.I.: Dagger Hilt
- Asynchrony: Kotlin Coroutines & Flow
- Storage: Jetpack DataStore (Settings) & SharedPrefs (Cache)
- Camera: CameraX API
This project is passionately developed by a student preparing for the Korean CSAT (Suneung). If Sensify has helped you, please consider supporting my journey and studies with a cup of coffee!
