(01) Design System

White canvas. Blue signal. Nothing else.

Fitness software competes with loud, busy interfaces. Coach Kit needed the opposite. A pure white background (#ffffff) with generous padding lets every product screenshot breathe. The page feels spacious because it is.

Cornflower blue (#4A8FE7) is the single accent. It marks CTAs, active states, and the “Get Started” button. One colour, applied consistently, builds a visual system that teaches itself. Users learn where to click without being told.

Typography is a clean sans-serif throughout. Bold weights on headlines, regular on body. No decorative fonts, no italics for emphasis. The restraint keeps the focus where it belongs: on the product UI being showcased in every section.

(02) Content Architecture

Product-first. Copy second.

Alternating feature sections with live UI

Each core feature gets a dedicated section: client management, workout builder, training plans, progress tracking, chat. The layout alternates text-left/image-right and text-right/image-left, creating a natural zigzag rhythm down the page.

The product screenshots are not decorative. They show actual interface states: a client roster with activity dots, a workout log with sets and reps, a chat thread mid-conversation. Coaches see their workflow, not a marketing render.

Social Proof

Dark-mode testimonial section

The testimonials break the white page with a charcoal background. Three coach reviews sit in card format with names and handles. Below them, Capterra (4.8), G2 (4.8), and Software Advice badges provide third-party validation. The contrast shift signals: this is proof, not marketing.

Feature Grid

Six-card capability overview

“Everything You Need to Coach at Scale.” Dashboard, Client Management, Workout Builder, Training Plan Builder, Progress Tracking, Client Chat. Each card pairs a small product illustration with a two-line description. Dense information, minimal visual weight.

(03) Technical Craft

No WordPress. No templates. No plugins.

Coach Kit is built on Next.js 16 with React 19. Every component is hand-written. The navigation, the feature sections, the testimonial cards, the pricing table, the six-card grid. Zero third-party UI libraries. Zero page builders. We own every line of code, and the client owns every line of code.

Images are served as WebP through Next.js Image with automatic srcset generation. Fonts are subset and self-hosted. CSS is Tailwind v4 with design tokens defined once. The full page with all product screenshots loads in under a second on a 3G connection.
