I am using this app from last two years and this app is good as good as it look in our mobile screen, this app is helpful in many ways but most in sending photographs and videos, i am an architect and when my workers or labors stuck in their work they just send me the photo of that particular problem or they make the photo of that problem and they send it to me and after that I just make the solution of that problem and send that photo or video back this is how my work will never stop, this is one of my experience with this app, i know whats app is growing and this growing where their is internet and the best part is that it take very small amount of internet so it is convenient and cheap.i choose this app because it is free and good for my work well this is the only work I have when ever I get board from my daily life I use this app to generate some money and when my work is complete I shut this app well the situation is just like to create some thing which is valuable but at very less cost so for better work and better accuracy use this app this is my advice to every one please at least try this app once you will definitely like this app.
