Is there a Shopify partner app similar to convertkit or clickfunnels?

[GuitarDojo]

Hello!

I'm curious if there is a Shopify Verified Partner App which will work like convertkit/clickfunnels/woofunnels? 

Currently - I run ads which re-direct to a shopify landing page, which allows them to see the free product and "check-out" - but feedback I'm getting from potential customers (and other online marketers) is that this is too confusing for people because they have to "check out" and provide details (even though no payment is provided). So I feel like I'm losing folks along the journey.

Further to that - I'd like to be able to deliver the free product on a landing page where they can view the lesson video then read my copy and click through to the ACTUAL sales page where they can buy my full course.

Does the description of my flow make sense? 
And is this possible with Shopify or an app that will work within it? 

I really don't want to have to signup for clickfunnels/woofunnels/convertkit etc.

Thanks! 
Any help would be most appreciated!
