FameLiker

FameLiker is an app that instantly adds likes to your Facebook posts, similar to apps such as Auto Likes Groups Facebook or Facebook Auto Like - Photo Likes.

You'll have to generate a token the first time you use the app, so Facebook can save your login credentials. Once you have generated the token, you can select posts and add likes and reactions.

The interface is very simple, and will clearly guide you through all the steps. On top of that, you can also select reactions to add to your posts, not just likes.

But just in case you run into an issue, Facebook Auto Like - Photo Likes has a video tutorial with step by step instructions. Give it a try and get instant likes!
