Design and Build Responsive Webflow Landing Page for Lead Generation

We are seeking a skilled freelancer to design and build a responsive landing page using Webflow. The primary goal of this page is to collect leads (emails and names) for an upcoming app.

The landing page should be clean, modern, and effectively communicate the value proposition of the app. Key sections required include:

- A compelling headline and introductory section.
- Sections detailing the app's features.
- An 'About' section.
- A section for testimonials.
- A prominent lead capture form for email signups.

The page must be fully mobile responsive across various devices and optimized for fast loading times. Strong copywriting will be essential for headlines, feature descriptions, and the call-to-action to maximize lead conversion.
