Shogun ‑ Landing Page Builder

This app allows us to do virtually everything we wanted to do when building a landing page. We initially chose it simply because it allows us to upload one image for Desktop and a separate image for Mobile but we have been pleasantly surprised by all of the other capabilities it offers. Plus their customer service is superb -- we can email them a question and they respond within 24 hours with an answer specific to our situation rather than just sending a canned response or link to a video. Highly recommended.
