There are simply countless apps with associated icons. Unless it's a more popular app we aren't likely to answer your question. If this is on your phone, just pull down the notification shade to find more information about the app. If this is a screen shot from another persons phone, asking them is likely your best route. It certainly doesn't appear to be a dating app if that's your concern.
We are asked almost daily to help identify an icon. Most of those questions are left unanswered. There is always an outside chance that one of our members recognizes the icon but it's rare. Welcome to Android Forums all the same.
