GoHomeMail is an Android app that allows users to send a message to their family/friends quickly with just ONE-PUSH when they go back home.
Additionally, the message informs the recipients of the fastest route and the estimated time from the current place respectively by the way: Walk, Train, Car, and Bike.
This application is very helpful in case you want to send a come-home message quickly when you are ready to go back home.
This application uses a plugin of itself to send the message in various ways (in the feature). As the default plugin, I've released the email plugin, GoHomeMailEmailPlugin. You can download it from GooglePlay, too.
Please search Google Play for plugins by specifying "GoHomeMail" like below.
