A free program for Android, by Amazon Mobile LLC.

Amazon Shopper Panel is an invitation-only program that allows shoppers to earn rewards by uploading photos of their receipts, as well as by answering questions about products they’ve purchased on Amazon. It’s an opt-in, invitation-only program, so only those who have been invited will be able to participate.

Participation in this program is completely voluntary. All users will be able to stop using the app, sharing receipts, or answering questions at any time.

Once you’re invited, you can start using the app to upload eligible receipts. If you upload 10 or more eligible receipts in a month, you’ll receive a reward. You will also receive short surveys about brands or products that may be of interest to you, and you can earn rewards for each survey you complete.
