Dear friends, I think anybody here registered in this website want to find something benifitable for your promotion and I am the same case. Recently, I intend to put a new version of my app to the app store. Before it's released, i would like to run some campain. Actually, I do have some efforts on it but little effect has gained. I guess it must be the reason of proper time. So could anybody here can tell me when should be the best time for promotion, Friday, weekend or Monday? and also the reasons. Thx.
