Level and measure
Read posture, check the tolerance, and use AR where supported; manual entry stays available whenever a device capability is unavailable.
Picture-hanging points
Enter the frame, hook, and target height to compute nail coordinates with their uncertainty context kept visible.
Projects and inspections
Group measurements, hanging plans, room checklists, and proof photos into local projects you can review and export.
Local reports
Export a report through the system share sheet; there are no accounts, ads, cloud sync, in-app purchases, or remote AI.
Important note
HangLevel is a household measurement and documentation tool. It does not promise millimeter precision, does not perform a building survey, and does not replace professional engineering or safety judgment. Camera, photos, and AR are used only when you choose the corresponding feature.
