U Samp is leading the charge in the area of mobile phone surveys and sampling. By allowing users to directly make money and have it show up in their account when they finish the survey, U Samp has created a demand for mobile phone sampling. This all takes place within an app that is available in the Apple app store or on Google Play. They have a high response rate of 25% and an incredibly high completion rate of 85%. U Samp's newest piece of technology utilizes geolocation within the phone that allows surveys to be sent to people at a certain geo location. Such as just after a new billboard ad, or in front of a new store.
