Curva: Angle Tracker

Curva is a private tool for recording and comparing personal measurements over time. Take or import a photo and place 3 points manually: the center of the base, the point of greatest curvature, and the direction of the tip.

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.
