LetsBumpIn app for iPhone and iPad

an app that lets you connect with people you see in real life in real time in a cafe or restaurant. Its a location based app and location wont be shared 24/7 , location will only be shared when you open the app.
You are sitting in a cafe with a bunch of friends, you see someone attractive working across the cafe. You exchange glances a couple of time but neither of you are in position to approach one another. Wouldn’t it be nice if you just had to open BUMP on your phone, look for their profile and send them a connection request, or better send them a Direct Message and see if you vibe?
