Tinder is one of the most popular dating apps with more than 100 million downloads. The company is now testing a feature which allows users to suggest matches for friends. The update allows users to recommend a profile by hitting the "share" icon. 

That share icon has another, very interesting use. Tap on that icon when matched with someone. This will then bring you to your "compose message" screen and inform a contact of your choice that you have found a match. It will also let the other person know exactly how many matches you've ever had.
