CountyTracker

# 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](https://www.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 - iPad Pro 11-inch (3rd generation) and later - iOS 16.0 or later ## Support & Feedback For bug reports, feature requests, or general feedback: - Shoot me an email at dev at bqrosen.com - Or open an issue on GitHub ## Author **Burke Rosen** GitHub: [@bqrosen](https://github.com/bqrosen) ## Acknowledgments - US county and national boundary data sourced from the US census bureau's [TIGERweb](https://tigerweb.geo.census.gov/tigerwebmain/TIGERweb_main.html). - SwiftUI framework and Core Location services provided by Apple. ## License This project is licensed under the **Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)** license.
