📖 How to Use:
1. Select the measurement type
2. Perform calibration (required once) - place your phone against the object under reference conditions
3. Press "Start Measurement"
4. Tap the object 3-5 times with a consistent rhythm
5. View the measurement results!

🔬 How Does It Work?
Every object has a different vibration frequency depending on its mass and density. VibeCheck uses your phone's accelerometer to record vibrations when an object is tapped, then analyzes the frequency to estimate the contents/condition of the object.
