The level reads roll, pitch and combined angle from the device's motion sensors, over a live camera view. It works on every device and needs no LiDAR.
Read
Hold the device flat on the surface or sight along an edge. It shows pitch as a roofing fraction such as 4/12 and as a percentage, and the wheel turns green with a tap of haptics when the surface is level.
Calibrate
Press Calibrate on a surface you know is level, such as a countertop, before you go up. Recalibrate if readings drift or after long periods in another orientation.
Save readings
History saves the current reading with a note (for example Main roof, south face) and lists the past ones with roll, pitch, angle, fraction, percent and date. Up to 50 are kept for a session. Swipe to delete one or use Delete All. Export all of them as a CSV that opens in Excel, Numbers or Sheets.
Level photos
The camera button in the level view saves a photo of the surface into the drawing gallery, rotated to match, so reports show what was measured next to the number.
The Site Plan layout can use your last Level reading as the pitch of a roof facet.
