Needs improvement
Not much to expect for a free app which is basically a store. The concept is simple - scroll through, see what you like? click to buy. Has greater potential, though.
There are only about 20 or so core design themes/concepts, the rest are variations on these themes. Would be better to organize them by theme, expanding the ones that look interesting to you.
The logos are very small - its hard to evaluate them. Would be nice to get an enlargement on rollover.
Where are these logos coming from? Can third parties offer their logo ideas for sale?
Another feature to consider is to allow some in-app customization - change colors, change text, rotate, flip, stretch, scale, combine elements, etc. That would make this a useful tool for initial design iteration.
