90° – Smart Alignment

Level picture frames, screens, door trim, shelves, and other rectangular wall objects with your iPhone. 90° detects visible edges, pins a stable target, and uses gravity-aligned AR wall geometry to show which side to raise. Confirm the object you intend to measure, follow the steady-position guidance, and wait for LEVEL. An optional zero can be saved locally for a named item after you verify it with a real bubble or laser level. Camera and motion processing stays on your iPhone. 90° has no account, ads, analytics, tracking, or network dependency.
