Product Hunt:

Have you ever wondered what products or apps you’re missing out on? It’s easy to find the most popular ones in a particular category—but what about the hidden gems? One of Product Hunt’s community members David Spinks has the same question. So, he asked other users: What’s one app you use a lot that most people don’t know about?

Actually, you probably do know about most of them but there might be one or two gems here you haven’t discovered yet.
