Don't know what database they have used for the app but it is riddled with errors in relation to the location of properties. About fifty percent of the time the app gives the wrong location of the house you are trying to find. It gives the location on the wrong side of the street, or the wrong location entirely on the street, or both these errors. Not good when you are using the app for deliveries. I'm using the Android version in the UK. Maybe the iPhone app doesn't have these errors!
