Not sure if I'm on the same wavelength as the other commenter, and I'm not a designer by schooling, but your page has 7 calls to action to purchase or download -- on my standard HD screen, I can have two pairs on my screen at a time, with the third just barely outside the top or bottom of the viewport. It's extremely redundant.
The contrast between the green headings and the white background is also a bit low. I understand that in this case it's your app's primary icon colour, but it's more difficult to read than it needs to be, especially combined with the light-weight font.
I want to chime in and say that, while I like the product itself (seems pretty cool), having the call to action after literally every paragraph of text feels desperate to me. It's like you can't speak a sentence without saying 'are ya gonna buy it yet?'. And if you asked me what would hook me in a bit better, I think it would be to flesh out the header above the fold first so it has a stronger impact and obviates the need to go in as much detail further down the page.
For another example, the graphic doesn't appear so clear and the main text doesn't feel very prominent. I feel like it lacks a sense of physicality that I'd want to feel from seeing a screen being shared to another device (a screenshot doesn't really hit the spot for me).

Sorry about that. I'll reconsider the placement of the buttons.

As in, alluding to the fact that ScreenTime imitates an external webcam and things like that?
> I feel like it lacks a sense of physicality that I'd want to feel from seeing a screen being shared
Would putting the screenshots inside a monitor help? What about animating the screenshot? Like a gif of the two users doing things on their own screens?
I'm not comfortable giving you a specific solution because I'm just telling you what I personally feel, and it's up to you to receive the feedback from me and the others offering it and decide how you want to address it. It's feedback, not advice.
Truly, I don't know what exactly I'd prefer from you because I don't know you or your product in any intimate way, so while I might tell you what I would have liked to see it doesn't mean I know that it's overall better than what you have.
