Vivino
iOS and Android; free. Pro version £2.99
Enjoying wine is a social pursuit and much of the fun of wine comes from sharing. So it’s hardly surprising that several social networks have emerged that help wine lovers connect. The concepts are comparable, and involve uploading wines as you drink them (usually by automatic label recognition or barcode scanning), writing a note and awarding a rating. You can follow and interact with other users, and it also acts as a journal of what you have been drinking. Vivino is the pick of the bunch. Set up in 2009, it has more than seven million users and boasts greater depth, interest and usability than its rivals. The Pro version enables you to upload and keep track of the wines in your rack or cellar. On the rare occasion the label-recognition software fails, Vivino staff fill in the wine details for you manually, but it takes time; Pro users get to jump the queue.

Delectable (iOS only, free) is similar but with a more lightweight design, and is also worth a look.
