Thanks, you could try to find a way to "connect" the cube with the text, also maybe the m meaning minute could be an ' or a kind of 60" timer...
Or you could try to elaborate different ideas, maybe just a cube is all we need... maybe the lego metaphor to suggest the component-based approach is also nice...
Could you further develop the idea? Maybe the keys could be surely shaped like iPhone icons, or you could use a different concept and associated artwork...
I'd suggest also to keep 1min of the same color to improve the readability, so basically you see two words: "1min" and "app"
If you could also include "powered by mobc3" as a footer that doesn't annoy too much it would be better
