Inspiration: We wanted a simple way for people to capture daily thoughts or short videos and get insights about their emotions without spending too much time journaling.

What We Built: Phronesis lets users record audio or video, automatically upload it to a backend, and receive transcripts with sentiment analysis. The backend uses Express, Multer, and AssemblyAI, and saves data to Firestore. On the app side, we used React Native and Expo for smooth recording and file uploads.

Challenges & Learnings: Handling camera/audio permissions, uploading files with multipart/form-data, and polling AssemblyAI for transcripts were tricky, but we learned a lot about full-stack mobile development and async workflows. Deploying the backend and connecting it reliably to the app was also an important learning experience.

Reflection: This project taught me how to combine mobile, backend, and cloud technologies to create a seamless user experience, and we're excited to build more apps that turn daily user interactions into meaningful insights.
