Friend Maker is an awesome app that costs 99 cents from the PEERS program at UCLA. It can be helpful for people struggling with social skills with autism, social anxiety or just plain social awkwardness. Here, you can learn how to exit and enter a conversation, deal with bullying and rumors among other things. I also appreciate how they have videos for some of the skills they are teaching. If you are interested in being a part of the UCLA PEERS program, it runs for 16 weeks and has a handbook as well. You can find information on their website here.
