Added a Getting Started Page - does it help?

My quick thoughts:

1. Yes, a Getting Started page is crucial. Hold your customer's hand.
2. The colors are far too bold - it may be your brand color, but that doesn't mean it must be used everywhere. You can restrict it to your logo, your navbar, border colors, or highlights. But to use a color as a background for text, it absolutely can't be so bright.
3. ~70% of the text on that page is unnecessary. I'm not exaggerating:

Sign up for an account and choose which plan you want to use. There are 3 plans available, Free, Small and Pro plans.

The main differences between the plans is the number of registered apps and the data retention period. The pro plans have an additional feature where you can receive SMS alerts to new crashes.

Paid plans come with a 14 day trial

We do not store any card information, this is handled by our payment gateway Stripe

The only thing the user needs to know to "Get Started" is the very first sentence. "Sign up for an account and choose which plan you want to use". The rest is either obvious or unnecessary for now.

(sorry for the curtness, I'm trying to be as quick as possible) Good luck!

Honestly, I think your design is a bit extreme colours-wise. I'd get rid of the red colour behind the text, get a nicer font and adjust your paragraph settings (bolder headings, more spacious text).

Also, images & video sell. I'd embed something.

I'd recommend reducing the amount of text and increase the padding between the paragraphs. It's quite overwhelming to be honest. Generally, the whole red colour is quite off-putting plus the screenshots of the homepage are hard to actually see.

Maybe try a standard landing page builder like Landingi.com and use a working template to see if that converts better.
