Matter Neuroscience: An iOS App for Emotional Fitness

An app for reflecting on positive memories

Matter Neuroscience helps people save meaningful memories and reflect on them. The iOS app includes a personal memory collection and conversations with M, its AI coach.

What I worked on

My work includes data storage and sync, authentication, automatic face detection in photos, and LLM integrations.

I worked with Core Data to store app data locally and CloudKit to sync it across devices. I also worked on authentication so people can access their accounts.

For the photo features, I worked on detecting faces automatically. My LLM integration work connects the app with AI conversations that help people reflect on their memories.
