What's the best Android app for checking property boundaries before starting a construction project?

LandMap is a mobile application aimed at simplifying property boundary identification for Android users. By integrating GPS with map data, the app displays estimated property lines over satellite or street views, which is invaluable for tasks like fence building, landscaping, or home additions. For instance, a homeowner planning a new patio can use LandMap to approximate the property edges and ensure compliance with local regulations before breaking ground. Key features include the ability to switch between map layers, measure distances directly on-screen, and save custom maps for future reference. User reviews indicate that the app is particularly praised for its ease of use and ability to access basic boundary information quickly, often saving hundreds of dollars on preliminary surveys. However, limitations are noted: accuracy can depend on local public record availability, with some users reporting discrepancies in rural areas or with outdated plat maps. A minor flaw is occasional lag when loading high-resolution imagery on older devices. While LandMap serves as a helpful tool for informal checks, it should not replace certified surveys for legal disputes or official permits. For everyday planning and avoidance of neighborly conflicts, it offers a practical, cost-effective solution.
