Although I’m all for some negative space every now and then (I supported graphics designers for 8+ years of my career…so they rubbed off on me!), I think there is a lot of wasted space at the top of the mobile apps. I think it could be compressed and still be very functional. I also think that the current mode should be added to the Dashboard. That is the point of a dashboard - to see everything in one place in a concise manner. I did a quick mockup of an example with a before and after - see below. I don’t necessarily like where it just says “mode:”, but I wanted to put something together as an example.
As you can see, I fit another row on the dashboard by just shrinking the header a bit without being detrimental to the overall look of the app.
Also, any time you have text over an image, you need to make sure that the text will be visible no matter what the color of the background is. So, I recommend that you place some shadows below the text so that it places a bit of a border around them so they would be visible against a light background or, and this is probably more common, a light section of the background.
