Level Things Turn your iPhone into a reliable, accurate spirit level and inclinometer. Level Things is a simple yet feature-packed tool for checking level, plumb, and measuring angles. In Level mode, audio tones guide you to level hands-free. The tone pulses faster as you approach level and becomes a solid sound when you're within a tenth of a degree. Two on-screen bubble vials — one horizontal, one vertical — give you an instant visual reference for both level and plumb. In Inclinometer mode, the current angle is spoken aloud at a regular interval so you can measure without looking at the screen. Set a zero reference to measure the difference between two surfaces. Use any edge of your phone as your measuring surface. Four on-screen buttons let you tell the app which edge is pointing down, and the display adjusts automatically. Calibrate the left and right edges with a simple two-point method for maximum accuracy. Freeze a reading with the volume down button. Fully compatible with VoiceOver.
