Nothing on progress

Another shoot, this time for the screen you'll see at first time when nothing is o
in progress. I change the button style, I made a plain button. I use helvetica font . I don't attach a full size because i'm working on the navigation bar icons, it's hard make an icon for an habit. any idea?

maybe a silly question, i have to say "on" or "in" for "nothing on progress". my english it's really bad as you can see.

what do you thing?
