Matter Neuroscience: An iOS App for Emotional Fitness

Making room for the moments that matter

Matter Neuroscience helps people reflect on positive memories and build a daily emotional fitness practice. The iOS app combines a personal memory collection with neuroscience and conversations with M, its AI coach.

My part

My work on Matter spans the data layer, account access, photo features, and LLM integrations. It brings together native iOS engineering and AI in an app built around personal experiences.

A foundation for personal memories

Core Data provides local persistence for the app’s data, with CloudKit syncing to keep that data available across devices. My work includes these persistence and sync systems, along with authentication for account access.

These are the foundations behind a simple interaction: saving a meaningful moment and coming back to it later.

Photos and automatic face detection

Photos are a natural part of remembering an experience. I worked on automatic face detection in photos, bringing image analysis into the memory experience and helping the app work with the people and moments captured in a picture.

Bringing AI into the experience

My work also includes LLM integrations. Matter’s AI coach, M, guides people through reflection, using conversation to help them explore their memories and the emotions associated with them.

Connecting those conversations with a native app brings the data, photos, and AI pieces together in one daily practice.
