Check in when you're there
Standing in a park? Open it and tap Check In. ParkStamp confirms you're inside the park and stamps it right then. Free, every time.

Add parks you've already visited
Scan your photos to auto-find parks you've already been to — or open a park in your StampBook and tap “Stamp It” to add a past visit by date. No photo access needed.
