###  KEY FEATURES

* **AI-Powered Coin Recognition:** Automatically detects EUR and CZK coins using on-device machine learning. No internet connection is required for measurement.
* **Precise Computer Vision:** OpenCV-based contour detection finds both the coin and your finger boundaries for highly accurate sizing.
* **Smart Screen Calibration:** Uses device-specific pixel density data for millimeter-accurate results, going well beyond what the standard OS reports.
* **Manual Adjustment:** Didn't get a perfect automatic detection? Fine-tune the circles manually on your screen for maximum accuracy.
* **Physical Verification:** Display a true-to-size circle on your screen so you can place an actual ring on it to double-check the result.
* **Multilingual:** Available in English, Czech, and German.
* **Privacy First:** All image processing happens locally on your device. No photos are uploaded or stored remotely.
