Bubble Level + Compass 1.9

A versatile bubble level tool that offers horizontal, vertical, and surface angle measurements, along with a true-north compass. The app boasts advanced functionalities, including surface level calibration to cater to your phone's case or camera bulge. It ensures a seamless experience by eliminating full-screen ads and intrusive pop-ups.

Originally a component of the popular astronomical app, Polar Scope Align Pro, this tool has now been released as a standalone free application due to the unique features it offers, lacking in other products on the app store. Users can also avail a Pro version sans ads, which provides additional benefits like Apple Watch integration, night mode, and pitch/yaw/roll rotation rate.

Basic Features:

• Bull's eye level showcasing surface angle reading, horizontal/vertical levels with angle measurements (in 0.1 degree increments).
• Compass displaying the north heading in both direction and degrees.
• Compatible with iOS 11.0 or higher.

Extra features:

• Magnetic declination reading to indicate the variance between magnetic and true north for accurate physical compass usage (requires location access).
• Accelerometer/Gyro switch allowing users to select the preferred motion sensor for optimal performance (default is Gyro).
• Magnetometer calibration display for precise compass readings.
• Gyro calibration to rectify lens bulges or uneven cases when utilizing the phone as a bubble or spirit level.
