RewardMe
What you get
Up to 5% cashback found in your email receipts (Reward Dollars / MDT crypto)
What is RewardMe?
Link your email account and it automatically finds purchases at 100+ merchants such as Amazon, Uber and DoorDash from the receipts in your inbox, crediting up to 5% in Reward Dollars. Redeem them for gift cards or convert to the MDT token (listed on Coinbase and others) and withdraw. Signing up with a referral code gives a sign-up reward, and once your friend earns a first shopping reward, both of you can claim referral rewards. The App Store publisher is Magic Crystal Limited (address in Hong Kong; updated as recently as Aug 2026)
How to start
