This is really easy job, no need any skills, simple, very short time...
I need someone that has his own iPhone (4 and up) for testing our amazing bio technology. you will have also a personal benefit from our bio technology for your own life.
I have to do the test 4 times every day, each test takes only 1 minute. and to do these tests for 1 month (30 days).
I will supply a document how to do these 120 tests. (each test is little bit different way)
After 30 days - you will finish your job.
