Seven Peach: Senior Social App

Seven Peach: Senior Social App

August 2024Completed

Why this project exists

The problem

We thought about older family members spending long stretches at home with few reasons to go out. We wanted to make it easier for them to find company and something enjoyable to do.

The product idea

We designed Seven Peach to encourage older adults to go out, take part in activities, and make friends, with an interface and recommendations shaped for them.

OVERVIEW

Project Overview

Seven Peach is a mobile application that empowers seniors to build meaningful connections through shared activities. By offering a curated activity recommendation system and a user-friendly interface, it helps seniors overcome loneliness and engage in their communities.

As the founder and lead developer, I drove the entire product development process:

- Designed and implemented the frontend using Flutter with a focus on senior-friendly UX

- Developed a personalized activity recommendation algorithm based on user interests, social participation, and location proximity

- Integrated Firebase Authentication and Firestore for seamless user management and data storage

- Conducted user research and testing with seniors to refine the design and ensure accessibility

Seven Peach is not just an app, but a solution addressing real-world challenges of aging societies, promoting social inclusion and active aging.
