A free program for Android, by GuideMeUp.
Developed by the company of the same name, GuideMeUp is a digital platform that allows you readily launch your very own interactive tourist, entertainment and/or culture guide - which should be compatible with most smartphones.
GuideMeUp lets you create your own guide using the microsite in the app. This should help you link up to your own webpage or URL, access you to online and offline maps from throughout the world, permit you to inject media content - from pictures and videos of places and such, add a series of recommended routes that you have discovered during your travels (that will be helpful to other users and/or clients), and more. It also allows you to have your own store alongside other published guides.
