I spent 5 minutes looking, and here is my very rushed take. What I see here is the same as I can get from a spreadsheet. IMO you need something to compel users to use your app instead of a spreadsheet. What features do you need? Well that's the hard part, because if you ask 10 users, you will probably get 30 answers. Do you use the app yourself? If not, start using it, if you already do, start adding what you need. I do like the simple immediate signup.
