Mobile and web app testing involves performing tasks within apps and providing feedback to help developers improve apps before public launch. Testers are typically given 15-60 minutes to complete a set of tasks while their actions and expressions are recorded. Pay averages around $10 per test, with some paying up to $100. By testing a few apps per week on various app testing sites, it may be possible to earn $100+ per month while providing an important service to app developers.
