I use very few iMessage apps, but I often use Pocket. Maybe I'll use this to text myself to read something I forgot about ¯\_(ツ)_/¯ From the blog post: iMessage apps are a fun and useful way to interact with your friends and family without ever leaving the Messages app. Now, with Pocket for iMessage, you can browse and search your saved items in Pocket and seamlessly share them without ever leaving the conversation.
