How many devices can talk to each other?

Technically, there is no limit to the number of connections that can be made, but usability-wise, you may want to avoid having too many. On the iPhone, 4 locations fit on the screen, but you can slide this section up and down to see more. I think a limit of 8 is reasonable for the iPhone. The iPad has more screen real estate, so it can fit 8 on the screen at once, and this is also scrollable, so probably a limit of 16 is reasonable.

Do I have to buy speakto for each of my devices?

Nope. If your devices share the same App Store account, then you can buy speakto once and use it on up to 5 devices. Also, we will be supporting the new “Family Sharing” feature, which will allow up to 6 different accounts to share apps, music, and books.

Can I speak to everyone at once?

You sure can. Pressing the big button button will let you speak to every at once, or you can press one of the location buttons to speak to just that one.

Do I have to keep speakto in the foreground?

No, other than making the initial connections with other intercoms, everything works in the background (when you are in another app or when the screen is locked). When someone is speaking, you will hear them immediately and get a notification so you can quickly get back into the app to respond.

Do I have to be on wifi? wifi

Yes! As speakto is designed for local use within a home or office, it requires that all devices must be on the same wifi network. All devices being on the same network means that speed and security are guaranteed! That being said, if a version that works over other connections would be useful to you, please, let us know and if there is a lot of interest, we could create a companion app or add-on.

Will speakto use up my cellular data? no cell data

Definitely not! All of the communication happens over your local wifi network, so no data is coming or leaving. This also adds to the security, since as long as your local network is secure, no one can eavesdrop on you.

Is there a delay/lag?

Not much. Unlike those other apps out there, speakto does not send your voice out to the Internet and back; it just goes straight from one device to the other. This means that the delay in most cases is less than 1 second, very reasonable to keep a conversation going.
