Interesting idea. I like the design of it overall and it flows nicely in all sizes. I think I would have to sign up and start using it to see how it feels. I'm wondering if there's a way you can sell the key benefits on the homepage better.
When I click any of these little app tiles, a detailed explanation opens but that's not reflective of how the app actually works when logged in, right? Instead of screenshots can you show interactive dummy data anywhere?
