Learning SOLID is an educational app focused on software architecture and development best practices. The goal of the app is to teach SOLID principles in a clear, practical, and applicable way for everyday development. The content is organized into modules, with one module dedicated to each SOLID principle. Each module combines theoretical explanations, real world examples inspired by professional scenarios, and practical exercises to reinforce learning. The app was designed for those who want to understand not only the concept, but also how to apply SOLID in real projects. The examples show tightly coupled code, common maintenance problems, and how to refactor into cleaner and more scalable solutions. In the practical section, users interact with a simple and intuitive interface, allowing them to practice concepts without needing to type code. This enables full focus on architectural thinking and understanding the responsibilities of each class or component. Main features of the app: Clear and objective explanation of all SOLID principles A complete module for each letter of SOLID Real world examples based on market problems Practical and interactive exercises Comparison between incorrect code and refactored code Content focused on architecture and best practices Simple interface for distraction free learning Learning SOLID is recommended for students, beginner developers, and professionals who want to strengthen architectural concepts, write cleaner code, and build systems that are easier to maintain and evolve. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | FULL PASS ALL APPS | $17.99 | one-time | | Premium access | $4.99 | one-time | | CERTIFICATE OF COMPLETION | $2.99 | one-time | ## Version history (last 5 releases) ### 7.0.10 — 2026-08-25 Completion certificates are now available, plus interface improvements. ### 7.0.8 — 2026-08-15 Certificate purchase flow improvements: store-guideline paywall and clearer copy.
