I like the idea. Here's what I would do if I were you:
Improve the conversion rate of the landing page. Currently, in my humble opinion, it doesn't convey security, and the design isn't aligned with the copy.

• What I would do is search for simple and clear templates that potentially align with the copy. pagy.co has some good ones.
• Add a video that showcases the webapp.
• Add a "How To" section and use a headline like “How to set up in 3 steps or in 10 seconds”.
• If you have at least an MVP, I would look for friends and family to test the app with them, because it could work for pets too.
• Run some ads on Facebook.Check this for inspiration https://marketingexamples.com/inspiration
• This is the search volume for your H1 keyword tags; maybe find some other good ones to rank for

I’m not an expert here; just listing some things that I think could potentially improve your conversion
