Overview
Crest and WallPreview are two distinct software products designed for very different audiences. Crest is a macOS utility that turns the MacBook's notch into an interactive hub for media, system stats, calendar, tasks, and more. It offers a free tier with four modules and a one-time Pro purchase for $19.99. WallPreview, on the other hand, is a web-based tool for artists, poster shops, and galleries to generate realistic interior mockups of their artworks. It provides a free tier (2 previews per day) and a subscription-based Pro plan for unlimited use and embed widgets.
