I'd have to agree with the parent. Finding an address has not yet been a big pain point for me while on my mobile phone. It's either in my calendar or in an email. And if not I can type it in or speak it (on Android) to get directions --- I typically remember the address.
While email search can be slow and cumbersome at times it's what I would consider "good enough".
I haven't used the app though and it might change my mind completely. I'd love to not have to open an application to start doing something. I'd like to speak an address or say a name or start typing a number and the phone be able to guess what my intention is and provide the best options. Sounded like that's in part what it does --- but I'd like that to be a native function of the phone, not provided via an app. Wonder how doable that is on Android. Presume not at all on iOS.
