A few comments:
- It could use a couple of smaller radius settings though (1km and 100m). Nothing that Chrome Console can't fix but not everyone is a developer.
- The intro page is a bit confusing, at first glance it might seem like an Android application, "Google Play" button being most prominent.
- The search bar is a bit short, if you just type the number and street name it's likely you'll end up in a different country or state.
