Manhole Quest — On-site scan with AR tracking, location verification, and target distance.

Normal recognition runs on the device. Assisted Scan uploads only after explicit submission and includes a fresh cover photo, precise location, the selected cover, and scan diagnostics.

How on-site scanning and collection progress work

Make every collection count.

Optional Game Center turns the progress already in your Album into achievements and collection leaderboards.

Game Center uses Apple's system sign-in. It is optional, and the core collection experience still works when it is unavailable.

Walk with context.

Research-backed guides connect the app to the public art, streets, and official sources behind the hunt.
