8 Android Apps that you can earn money

# Little Savings

As one of my friend requested, could you analyse any apps that can earn me money? I started to Google and installed some couple of apps and tried few more.

Behind using the app, I tried to understand the core of app and categorising as follows.

1) Resellers:

This become the most trending way after the more house holders/women utilised their free time to earn some bucks.

How it works?
The products catalogue from whole sale retailers are collected and avaialble foe sale. By adding your commission(10-40%), you can resale to other persons.
Eg., a dress costs 200 in catalogue, you can resale to buyers(you need to get it by whatsapp) or your friends with a commision of 20%, say 220.
If anyone buys it, the 20 rupees will credit to your account and 200 will go to the retailer.
