Our clinometer, spirit Level, protractor, bubble Level - Multitool is extremely precise and intuitive to handle. These intuitive features are packed in the Measure App level tool with easy user controls and intuitive handling. ■ 360° clinometer ■ Use the clinometer the measure angles along all edges of your phone. You can set a target angle by moving your finger across the display. Additionally you can store up to 5 angles in the angle list and recall them quickly as target angles. Approaching the target angle or the 90°/180°/270°/270° angle (according to your setting) you can receive different acoustical warning depending on the difference between measured and targeted angle. Protractor-Multitool also features a stability indicator indicating the rate of change. ■ Spirit level ■ Approaching 0°/90°/180°/270° a spirit level is displayed. This enables you to precisely level things. ■ Surface level ■ The surface tool enables you to level surfaces. Level differences will be displayed in degrees. ■ Intuitive ■ Depending on the orientation of your iPhone the view transitions from surface level to 360°-protractor. In addition to that spirit levels will be displayed when approaching cardinal angles. ■ Highest precision ■ The 6-point calibration assistant guarantees high precision up 0.01°. Surface level and protractor calibration are completely independent of each other allowing for even higher precision. ■ Sophisticated design ■ Measure App native drawing capabilities of your phone for extremely clear and fluid display.
