The concept is great. I appreciate it only sends in notifications during lunch. Great reminder to go get lunch. However it is very buggy- i have these notifications for unread messages out that i need to respond but I've read everything and responded. What's up with that? And then you claim to have stats about this response rate, if the responses aren't updating on the users' end what's it's based on. Also disappearing chats... And how the heck can you unmatch someone?! It should be easy
