Thank you for your good intentions @Icedrum.
Hopefully I can buy this application because the currency in our country is very small when compared to US dollar. Currently I am still using Xaiomi 4a handphone. Currently the mobile internet network in Aceh is not yet strong, what else if I go back to the village. Sometimes if I study on the internet I have to go to the city sitting in a coffee shop to find a strong internet network belonging to a state company that is channeled through a modem in some paid coffee shop. Today I am still in the village and I use the internet network seluer in connect via hotspot to computer. The cellular network is weak and often dashed. I apologize late for your comment, and I am happy to meet and read the article.
