I built a study battle app and need honest feedback Hey everyone, I’m a student building StudyClash, an app that turns practice questions into competitive study battles. You can try a deck, answer questions, get a score, see what topics you’re weak in, and use an AI coach to understand mistakes. I’m not trying to sell anything right now — I just need honest feedback before I show it to more people. Main things I want feedback on: Is the app easy to understand? Does anything look b
