Fastask（ファストアスク） is a Japanese survey service operated by JustSystems Corporation. It offers a smartphone-exclusive response screen, making answering surveys incredibly smooth. By answering surveys and participating in chat interviews from companies and organizations, users can earn points that can be exchanged for cash and other rewards. The app has obtained the Privacy Mark, ensuring user privacy and security.

With Fastask, users have the opportunity to earn up to 7,000 points for a single request, particularly through the "Text Chat Interview" option. Additionally, a large number of surveys targeted specifically towards users are delivered daily, with push notifications to ensure users don't miss out on any opportunities. As surveys are on a first-come, first-served basis, it is encouraged to answer as many surveys as possible.

The points accumulated can be exchanged for a wide variety of products, including cash, gift cards, and other points, through PeX (Payment Exchange). Please note that this app is only available for residents of Japan and is operated independently by JustSystems Corporation, with no affiliation to Apple Inc. or its related companies.
