Frequently Asked Questions

• Q: What's the difference between Normal Mode and Camera Mode?A: Normal Mode uses your device's built-in sensors to measure angles when the device is placed against a surface. Camera Mode allows you to measure angles visually through your device's camera without physical contact with the surface—ideal for hard-to-reach areas or large objects.
• Q: Which measurement mode is more accurate?A: Both modes offer high accuracy when used correctly. Normal Mode is typically preferred for precise measurements of accessible surfaces, while Camera Mode is excellent for remote or visual angle measurements where physical contact isn't possible.
• Q: How accurate are the measurements from Protractor Measuring Angle?A: Our app uses your device's built-in sensors and camera technology to provide highly accurate measurements. For best results, always calibrate your device before taking important measurements.
• Q: What's the difference between the free and premium versions?A: The free version provides basic angle measurement in radians only using Normal Mode. Premium subscription unlocks additional features including Camera Mode, degrees and gradians units, target angle alerts, vertical measurement orientation, and advanced precision readings.
• Q: How do I calibrate my device for the most accurate readings?A: Place your device on a surface you know is perfectly level, then tap the "Calibrate" button. Follow the on-screen instructions to complete the calibration process. We recommend recalibrating occasionally or when moving to a new work environment.
• Q: How do I use the target angle feature?A: Premium users can set a target angle by tapping the "Set Target" button and entering their desired angle. The app will alert you with sound and vibration when your measurement matches the target angle.
• Q: How do I switch between different measurement units?A: Tap the unit indicator in the bottom corner of the screen to cycle between available units. Free users have access to radians only, while premium subscribers can choose between degrees, radians, and gradians.
• Q: What applications is this app best suited for?A: Protractor Measuring Angle is ideal for carpentry, construction, DIY projects, furniture assembly, roof pitch calculations, and any other application requiring precise angle measurements.
• Q: Who do I contact if I need help?A: For further assistance or any questions, please contact our support team at [email protected].
