首创的应用程序，奖励你只需观看广告。
Get yourself introduced to the first of its kind application that directs advertisements to your Smartphone - based on your profile, location, and preferences. COA, formerly known as CashOnAd, rewards you for simply viewing the ads for 6 seconds or more on an incoming call. In addition to that, COA also allows you to earn rewards simply by viewing the lock screen ads & unlocking your mobile phones.
