The app would be much easier to read, and would also look a lot nicer if it could have a different shade of colour on heading rows, again also easier to read if the heading row text was bold.
At a glance the entire page looks pretty similar, only difference is a barely different shade of grey on the heading rows, so this makes the UI harder to read / use. It would also make the app look nicer having some colour there, as an example in my screenshot below the heading rows could be bold and have a very light shade of orange.
