In general I understand what you're offering so the landing page basically does its job. However some minor styling suggestions:

"try for free" and related text is basically unreadable. Use darker font when you have a light background.

Same with the over state on your free trial button, use white text in this scenario because you have a darker bg

IMO Login UI should also not use a dark background, it looks out of place since the rest of the theme is light

i can immediately understand what the product does which makes it superior to 90% of everything else out there

@ben and @grantsingleton already gave great feedback, so let me add one more thing for the above-the-fold section.

The H1 says that you offer affordable social media scheduling. That's clear, but I expect you to elaborate more – about the affordability – in the later paragraph. Something like "ScheduleWave covers <insert all benefits> without breaking the bank."

Btw, how can you write so many blog posts in a day? 😅 So many things to say about the blog, but since it's for the landing page. So...

Good luck, Lars.

ScheduleWave has a lot of potential! 🔥

understood what it does instantly, overall looks good!

one quick comment, since it's a roast:
the social icons on top, plus the animation on the right, it's a bit confusing.

It could be clearer if you post the icons as a collage instead of the animations revealing one by one? so group the visual idea of "all social icons" in one place.

Display it stronger once, show you have them all, instead of having them displayed in 2 places, but neither being very strong? (having the small icons on top left looks like they might be your own social media links, you can fix this if you switch up the horizontal layout, and on the right revealing them again one by one doesn't seem to add much)
