If you’re in a tough rental market such as the District, it can be a pain to keep up with all the real estate sites regularly enough to jump on places that match your criteria. Although it’s not perfect, PadMapper can make that experience a lot less painful. A nice way to streamline the listings from Craigslist and other sites with rental listings, this app uses Google Maps to show you the basics: where the rentals are, how big they are and how much they cost.
The listings aren’t comprehensive, but it’s a great tool to start narrowing the field. You set the standards for what listings you’d like to see, meaning that you can let the app take care of the rest. Free, for iOS.
