1. Ditch the two pulsing animations. I tried to click on the pulsing animation top-left and nothing happened.
2. The logo is hard to read. Consider simplifying your logo, but keeping the flashing red record icon on home page.
3. Keep content above the field. I didn't know I could scroll.
4. Don't make me sign up to try it. Why can't it show my webcam feed on the home page? At least defer sign up after you've given me a link that will let me broadcast my feed, then I can sign up on my phone.
5. The flashing recording icon is distracting after the initial "I get it," e.g. on the register page.
6. Be more up-front about T&C on your access to the feed.
7. Nowhere on the site does it say, "Why do I need this?" Said what you said in your post here on your website. "Hey, I'm Geoff. I wanted to keep an eye on my kids & my pets, so I made uView to save money on a camera, now you can save too! Here, give it a try: [Request Webcam Permission]"
8. Hard to read the features with the pulsing thing.
9. The weight of multiple call to actions conflict: Register, Login and "Try Free Now" all feel equally heavy.
10. Hard to read centered text on privacy policy: https://www.uview.io/privacy - also, put Privacy as a main nav link.
11. Consider making it free for 5 minutes, then you have to keep clicking to refresh. Or, an ad-driven business model where you show highly-relevant ads overlaid in the feed, since you know the person using it is interested in security.
Good luck!
