CountyTracker

Making maps of the counties you've been in is fun. I got into it when I realized I just needed three of four more to complete all of Califonia. Now there's an app for that. CountyTracker is a lightweight, privacy-focused iOS app that overlays county boundaries on Apple Maps, automatically keeps track of counties you've visited, and fills them in to build a personalized map of your visits over time.

Features

• Running counter of your total number and percentage of US counties visited.
• Long press on unexplored counties to get driving directions to them in Apple Maps.
• Export map snapshots directly to your Photos library for sharing.
• Import and export mapchart.net-compatible county file lists (aka configuration .txt files). I have no affiliation with mapchart.net, but I'm a big fan.
• Manually add counties in-app
• Background tracking: If enabled, CountyTracker uses Apple's low-power location services (Significant-Change Location Service and the system CLVisit APIs), which rely primarily on cell‑tower and Wi‑Fi-based location rather than continuous GPS. This provides system-delivered, infrequent visit/location updates with minimal battery impact while remaining accurate enough for county-level tracking. It requires the Always location permission; you can disable background tracking in the app or revoke the permission in Settings.
• Includes US county-equivalent subdivisions for US territories like Puerto Rico, Guam, and the USVI (toggleable).
• View in eight colorful themes: Light, Dark, Nord, Snow, Sepia, Outrun, Cyber, Jungle

Privacy

CountyTracker is fully open source and runs entirely on your device. All location and visit data are stored locally; nothing is collected, transmitted, or shared with the developer or third parties.

Monetization

This app is free to download with all features enabled and no ads. There is an in-app tip jar if you're feeling appreciative; making any in-app purchase removes the tip jar button.

Location Permissions

The app requests two types of location permissions:

• While Using: For manual county tracking during active app use
• Always: For background county tracking (optional)

Prerequisites

• iPhone 12 and later
• iPad Air 5th generation and later
