If you choose to save one, it stays on your device with the app data. Key features: - Manual angle measurement with 3 points - Top and side views - Private traces and measurement history - Comparison between saved dates - Optional personal notes - Report export and sharing - App lock with Face ID, fingerprint, or device passcode when available Curva is a personal recording and comparison tool.
