Braintain is a mobile app that helps you remember what you learn using AI-powered flashcards. It generates visual flashcards automatically to make concepts easier to retain and review over time. It’s designed for students, developers, and curious people who want to stop forgetting things they study. I’m currently looking for feedback on: Onboarding clarity (is the value clear in the first minute?) Flashcard experience (are they engaging and useful?) Overall retention feeling (does it actually help you remember?)

HolyNit helps you sharpen your technical instincts by reviewing real-world pull requests instead of solving artificial coding problems. As AI-generated code becomes more common, the role of engineers is shifting. Writing code is no longer the only core skill. Increasingly, engineers are expected to evaluate, refine, and take responsibility for code produced by AI systems. And no matter how advanced these tools become, there will always be a human in the loop as the final checkpoint, because production systems still demand a level of judgment and accountability that AI alone can’t provide. With HolyNit, you practice identifying real bugs, edge cases, and design issues in authentic codebases. You receive detailed feedback and a performance score, so you can see how your reviews stack up against professional standards. More importantly, you gain insight into how experienced engineers think by comparing your reviews with theirs on the same pull requests. Over time, this hands-on approach helps you build a critical, structured review mindset -- one that goes beyond syntax and correctness to include readability, scalability, and long-term maintainability.
