Very useful (at least for me) application. It's the second alternative to a full dialer, next to the speed dialling app.
Many people do actually use the call log more often than the actual address book on their phones. That is the idea behind this app: scroll through the log and find who you want to call.
Optionally, the SMS messages are listed in the same log. The message body is not displayed, this may be a task for me in the future. I was thinking that it is not necessary to do, since the message arrives and is readable in whole on the smart watch in any case.
It works with all Connect IQ watches, and is made to support both touch and keys input.
