Launch rock collects emails and that's about it. LookAft is all about tracking 'conversions' to see what % of visitors would likely sign up and use your service. It also includes a preliminary pricing page so you can test price points (which is obviously important to see if a product vs customer acquisition balance works out) by seeing how many people click through each price point and give their emails. Please let me know if you have any other questions.
