Whether the value proposition and how to use the app is clear on the homepage

Yes

If you would use the app

I'm not a target customer I believe

What other improvements you would like to see

Small points:
The background is very distracting whilst reading I'd recommend not changing it like this
The homepage is missing a title attribute
The Login button should probably be Sign up instead, this is a common pattern to target new users primarily as their intent is lower

I'm a big fan of the gradient text and the name :)
