Untappd is so 2011. Buy Your Friend a Beer with Tweet-a-Beer!
When I signed up, and accidentally sent myself $5 (or more accurately gave Chirpify, a Twitter payment app, ten cents for the transaction), I looked for the mobile app, but couldn't find it in the app store. Chirpify will DM me with receipts, but I don't know how to accept payments on the go, without opening Safari on my iPhone.
