"Must-have" - I've just learned this word. Nice! Well, Since I've got my first smart phone, there are 3 kind of must-have apps I use! 1st - What's App - This app is very important to my routine, chatting with friends, relatives, parents and I use it for work as well. 2nd - Music Apps - To listen music is always good for mind health and this kind of app is very useful when I'm washing the dishes! 3rd - Bank Apps - Since I've started using bank apps, I rarely go to the bank agency and to pay counts become much more easier, just doing it using a smart phone. That is it! #HelpMeCorrect
