Earn PayPal Ca$h for Downloading Games and Apps
AppDown is one of the easiest and most reliable money making tools for the phone apps that I've ever seen.
The basic premise is that every day, there's a featured free app for you to download. You then download the app, play around with it for around 30 seconds, and then you can delete it.
Each time you do this, you earn somewhere around ten cents (it depends on the app). With just doing these daily features apps, you can make around $10 per month once you take into account the random bonuses that they throw in (download the featured app for 3 days in a row, like us on Facebook...)
This alone is pretty good for spending around 1 minute per day downloading an app, playing with it, and deleting it, but AppDown also offers a really good referral program to go along with it. You get 50% of all the money that your referrals make downloading app, 20% of all of the money your referral's referrals make, and 10% of all of the money your referral's referral's referral's make.
So you can easily make around $50 per month with this with just a few referrals.
