Wallrap app analytics for September 14

Wallrap is an acoustic stud-finding aid for DIY wall checks. Rap the wall, let your iPhone listen to the pitch and decay of each knock, and see HOLLOW, EDGE, or SOLID with a confidence ring. Wallrap includes live listening, tap-and-trace wall maps, Edge-Lock center guidance, spacing estimates for common framing patterns, saved history, CSV export, and Mount Check reports for practical verification before hanging or drilling. All processing is local. Audio is processed live and discarded. Wallrap has no accounts, ads, analytics, tracking, subscriptions, cloud processing, or unnecessary permissions. Wallrap is an estimate, not a precision instrument. Always confirm with an appropriate pilot hole, hardware stud finder, or professional guidance before drilling, mounting heavy objects, or working near outlets, switches, plumbing, or unknown wall cavities.
