MobileXpression is a passive rewards app that pays you
for participating in market research by tracking your mobile internet
and app usage in the background. After you install it, it uses a VPN/phone
permissions to collect usage data and turns your participation into
weekly credits that you can redeem for rewards like gift cards
(Amazon is a common option), as long as the app stays active on your device.
