The program display house numbers after the street address, like “Anywhere Ln. NW Seattle WA 1234”; the company confirmed this was a design choice, not an error. That might be noted as an interface oddity, except that the software was unable to recognize any addresses that other apps had no trouble with. Maybe better: the software was unable to accept any addresses from the iPhone contacts list; other software had varying levels of success. We reported this with examples to the firm in 2009, and have seen no improvement in the interim. Until that problem is fixed, we must recommend against this app.
