There are many mobile apps that you can use to make money easily. Now I want to share one to two apps for you to learn how to make money with them
First I will introduce you Trymyapps which is an app sharing benefit with users. When users download a task and finish it, $0.4 will be rewarded for per task. It is easy and quick as you can do all these steps within 4 minutes. Although the tasks sometimes may be in large amount but sometimes with no task to receive which is the annoying point I do not like.
Now I will introduce specifically for you how to complete a task:
1. Just download a free app from Trymyapps.
2. Try out the app for at least 4 minute.
3. Once you've tried the app, you will directly get $0.4 for per task
Download Trymyapps for iPhone/iPod now.

Plus, you can get even more rewards when you share your referral code with your friends on iOS. You get 50% of their rewards for the first ten tasks.
Requires*IOS*: IOS7/8 for iPhone/iPod

I will also simply share you another app that is bestreviewapp. You can use your android, ios, mac device to earn money just by writing reviews for apps they provide.
Now I hope this will be useful for you to earn more money easily.
