We are an IOS APP development studio, we release many apps in a monthly basis for us and for our clients that are mainly US based.
The job is quite easy, you just download and test for few minutes our new apps and games and give us your feedback so we can improve them, and Get Paid.
All apps are available on the US store only so it's IMPORTANT that you set up your Itunes account to the US Itunes store this article might help
There's tons of other articles about this just search on google.
We pay $5 every 10 apps feedback, so $0.5 each. We release many apps weekly, so it's a long term collaboration.
Please don't respond unless you have an US Itunes account.
