AQA is a free social and communication app developed by Marslab Mobile for Android devices. The app allows users to share their aqa.link on their social media stories and receive anonymous responses from their friends.

AQA is simple and easy to use. To start, users can create a free account and generate a unique aqa.link. They can then post this link on their Instagram or Snapchat stories and their friends can click on it to submit anonymous questions. Users can view the responses on the AQA app and choose to share them on their stories or keep them private.

The app also provides an option to add the aqa.link to the user's Instagram bio, which can increase the number of responses. Overall, AQA is a fun and engaging way to connect with friends and receive anonymous feedback.
