How does the coin relate to anything? I only kind of get it from the conversation in the last screenshot but not really. The last screenshot also contains some 'pickup attempt' so it makes the app look like a dating app, but I am not sure if it is.
coins are geo tagged, and if you pick someone's coin from somewhere there is communication link created between you two, and vice versa.
idea of the app is to be generic not just dating, but yes dating is one of the use case.
user can drop a coin and pick a coin, and the places they usually goes to is attached with their interest, eg: cafe, pubs, gallery, museum, church or some event. so more likely you gets to connect with like minded people.
