Looks good overall. Couple small things:
1) Show a couple more screenshots so we know what exactly it does
2) I see this a lot and it drives me nuts: DailyChomp, but the logo shows dailychomp. The logo also looks a little out of place.
3) I would give the option to collect email addresses too.
Lastly, and the most important... start A/B testing right now. Try testing the wording in that button first and go from there.
