This is my first iOS app. I built it with React Native.<p>It allows users to post messages to a specific location (the location where the user is when they send their message). If another user comes to the location of the message, that user will receive a notification telling them they've discovered a message. It will then be added to the user's collection of messages, and the user will be able to read it. I've thought of the app as "Pokemon Go for messages".<p>Any thoughts? Constructive criticism? Planning to continue to work on it and add features to it.
