Based on the users' reviews on the Apple App Store, here are three pros and three cons of the "Run and Build 3D" app: Pros: 1. "Easy to use and understand, perfect for beginners in 3D modeling." 2. "The 3D animation feature is impressive and fun to experiment with." 3. "The app has a vast library of pre-made blocks and templates to work with." Cons: 1. "The app crashes often and loses my work, very frustrating experience." 2. "Limited customization options and tools are available, especially for advanced users." 3. "The app's search function is slow and often returns irrelevant results, wasting time." Let me know if you'd like me to summarize the reviews in a different way!
