MR.E - Mystery Shopper Corp. is a free Android app developed by Desarrollo Comercial that allows you to become a certified investigator and get paid for your work. The app offers challenges that require you to evaluate different aspects of establishments you visit, record your findings, and provide evidence to receive your payment.

To become an MR.E investigator, you need to download the app and complete the registration survey. You'll need to certify yourself to be recognized as a certified investigator and then complete challenges near your location. However, you must remain incognito while completing challenges.

To be an MR.E investigator, you must meet certain requirements. You must be over 18 years old and have an Android device running Android 4.0 or higher with a camera and GPS for geolocation. You'll also need mobile data to complete challenges and a credit card or interbank transfer account to receive payment for approved challenges.

The challenges are available throughout Mexico, and if you become the best investigator, you'll gain access to unique challenges. You'll receive payment within 72 hours of your challenge being approved.
