I have just started developing apps for android. For my first app I have created WFS: WhatsApp File Sender. It lets you send any type of file (size up to 160 MB) through WhatsApp.
Please download my app, write a nice review, give 5 stars and G+ it. Keep it installed for 15 days. Few clicks on the ads would be nice as well.
I’ll do all the above mentioned stuffs as well.
Don’t forget to tell me your playstore username.
