There is an apps for androids device in Google playstore created for tourist. The apps is very simple and the looks also not very sophisticated. The main function is to give information about the destination of interest around the globe in text.
Although got good rating in playstore,information about Malaysia are very limited. Only Melaka / Malacca and Georgetown in the apps. Looks like UNESCO heritage listing also make an impact as small as this,awarenes to many independent smartphone apps developer.
