Why is the Bump Android app 2.74 megabytes large? That seems excessive.

Huh, that doesn't seem to be a welcome comment. I'm not sure why. Bump doesn't strike me as an app that ought to require large media files. Does it contain any? If so, why? Is the binary itself that big? If so, why? Large dependencies? Either way, the size stopped me from checking it out: it takes up space on my device, it takes work to move it to the SD card and if it updates regularly that means more relatively large downloads.
