That's ringing my alarm bells real hard. It has none of the things you'd expect on a website for something like this. Where's the git repository link? Why is the download button linking to a totally different domain? Why is it called an "app"? Why is it called "Lemon" just to target people who have used the legitimate lemon-named service? User has spammed links to this service for a week straight?<p>99% chance, in my opinion, that this is malicious.
