For your company, we can develop a GPS and Google map oriented application similar to this demo version.
STORY: Your client is stuck somewhere and needs to send you exact location. This app locates you and prepares latitude/longitude forming SMS or E-mail and send it to you.

Upon our agreement some options can be added, removed or locked and a new app will have the name of your company, of course, with an icon with your company logo.
That's the way you can get a customized application for your company and help your company to be different than other companies without their own android app on Google Play.
You can choose which color theme fits your needs.
