Response from developer

We strive for high accuracy in angle measurements, and the error should generally not exceed 1°. We suggest taking a look at the instructions or the short demo videos included in the app to ensure proper usage. And, please check the measurement mode, as the program has two modes: measuring plane angles and measuring dihedral angles in space. In our experience, most issues stem from selecting the incorrect mode. If you’re still experiencing an issue, please reach out to us via the feedback option available within the app.
