Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Fabula for SwiftUI
Explore narrative construction and code organization using fabula and syuzhet concepts. This app serves as a personal project to learn SwiftUI, offering code collections and fostering developer community interaction. It aims to help users understand SwiftUI's declarative approach for cross-platform development.
- Narrative construction concepts (fabula & syuzhet)
- SwiftUI code collections
- Declarative UI development learning
- Cross-platform development (iOS, macOS, watchOS, tvOS)
- Developer community sharing
- Regular code updates

The formalism used the concepts of fabula and syuzhet as a way to develop narrative construction or classified materials and compositions into fabula and syuzhet, respectively. The totality of microscopic events listed in causality was called a fabula, and the narrative arrangement of these motifs in an artistic way was called a syuzhet. This app is a personal project to learn the technical ingredients of SwiftUI and derive creative results. SwiftUI is a user interface toolkit that can develop applications in a declarative manner. This is a modern development method that communicates to iOS how you want the user interface to behave and finds out how users perform when interacting with the interface. In addition, SwiftUI can develop macOS, watchOS, and tvOS with the same code as well as iOS development. The most appealing thing for me personally is that it is easy to learn and that the code is concise, making it easy for beginners to understand. I hope this project will help everyone, including myself, to understand SwiftUI. The code of this project will be updated regularly. You can share and communicate with developers around the world through the Fabula app. We always look forward to the participation of developers.
PSRayTracing
This application provides a graphical interface for a ray tracing engine, designed to render images faster than reference code. It includes features like threading and render progress visualization, based on "Ray Tracing in One Weekend" books.
- GUI frontend for ray tracing
- Faster rendering than reference code
- Threading support
- Render progress visualization
- Toggle-able features
- Based on "Ray Tracing in One Weekend"

This is a GUI frontend for the PSRayTracing implementation of the "Ray Tracing in One Weekend" books by Peter Shirley (and others). Which renders the images in the book faster than the reference code, but also offers other features (e.g. threading, render progress, toggle-able and more). The source code for this program, as well as a report auditing all of the changes/improvements, is freely available at: https://github.com/define-private-public/PSRayTracing

Verdict
The clearest difference is update cadence: Fabula for SwiftUI at fortnightly against PSRayTracing's every 30 months. Fabula for SwiftUI also leads on ratings volume (123 vs 2) and device support (4 vs 2). PSRayTracing's advantage is rating (5.0 vs 4.8). On price, review sentiment, ads and in-app purchases there is nothing between them.
