Tinder Gold works much like Tinder does, except for a few key features that are only available with the more premium subscription tiers like Gold and Platinum.
The most desirable of them is the new "Likes You" feature which shows you all the people who swiped right on you, and also gives you the opportunity to match with them, dismiss them, or go through their profile more thoroughly before making a decision.
With Tinder Gold, you will also get unlimited likes, 5 Super Likes every day, 1 Boost per month, and the Passport feature which allows you to change your location.
