This application will get you many 'likes' with hardly any effort at all. To do so, you need to earn the necessary coins to buy your likes by voting for photos that other users are trying to make popular.
Once you earn enough coins, you can use them to increase your number of favorites. With 20 coins you can get 10 likes, and with 50 you can get 28. You can buy up to 8,000 likes with 10,000 coins.
Other users will also vote to earn coins, so with some luck, you will get many more likes than the ones you buy. This way, GainLikes for Instagram will help you gain presence on the explore tab in Instagram, increasing your number of followers instantly.
