I have use this app for some time what I found that as this app mention this this is for netherland so this app is not acceptable globally. So as a indian I cant say anything about usefullness but instead of this concept is good as there are more like app in market which are globally accepted amd working properly.hope someday it will be accessable through out the globe.layout and design are simple data accessing can be reduce if they try.
Freature are somehow same nothing different from the other app like this.
After all I would like to say that it need to improve to become more popular .
