I am currently working on a product idea and I want to test in the market whether people would actually like it that much that they would actually use it. Now I designed a landing page (www.zuster.me)and added a download button which is not really downloading the app. This is my conversion indicator.

There is also the common practice to have an "early access" signup feature instead.

There are not that many discussions around the question which of the two works better to validate an idea. What are your thoughts? Also happy for any readings on that topic!

Thanks!

Fabian
