Mike has 2-and-a-half-year-old and an 11 month old so seeing the holiday lights are big for his family!
If you have a house decked out in lights, you can add your house with pictures to the app. If you're looking for a house that's all decked out, you just search for houses in the app. You can also add tips and comments for each house.
Right now the app is only available for iOS, but an Android version is on the way.
You can check out the app here.
