At small breakpoints, the UI (especially the "try it now" button) can overlap some text. Sizing also seems off.
Another issue I noticed is the play button itself, the entire circle area is clickable, however only the play/pause icon can actually be clicked.
There are also numerous accessibility issues. If you're going to advertise this as something to improve accessibility, it might be good to actually concentrate on that for your landing page.
I do hope the UI can be improved, as the product looks solid.
I would suggest you now focus your attention elsewhere. Wordpress is a great eco-system, but if you want to earn more, dive into Javascript with ES6.
From there you can pick-up a UI framework (I would personally suggest Vue.js), and move onto exciting large-scale front-end applications, with a better pay-check.
I've almost doubled my salary moving from a Wordpress developer to a front-end engineer in a years time.
This uses react-native, I would not consider jumping on the Vue ship if you've been waiting for a native solution.
This seems more like a hack-y way of going about it.
Some other solutions are out there, one of the main ones being nativescript. However it feels like the community still hasn't "agreed" on a solution like React did.
To my knowledge, Vue still does not have anything official around native.
I would consider waiting for now, unless this proposed solution suits you.
(This doesn't mean you shouldn't start using Vue elsewhere however, I have been using it for the past few months at work on a pretty large-scale project and it is my favorite library by far, for many different reasons).
Your website, ironically, breaks at a smaller viewport (at least my small screened firefox on desktop).
I would really consider making this work on tablet / mobile devices, and fixing the accessibility ASAP. Especially considering the product you are trying to sell.
How can I trust your phone hardware if your website doesn't meet modern day standards?
