Introduction

Vipriya stands out in the dating app scene with its unique approach to matchmaking, leveraging Spotify music API. Vipriya's algorithm, inspired by the Sørensen–Dice coefficient, goes beyond conventional matching, considering both shared interests and diverse personalities for enhanced compatibility. With a focus on personal growth and exploration, Vipriya encourages users to learn and discover new genres together. Vipriya, where uniqueness meets compatibility, redefines the dating experience by bringing people together through the magic of music and diversity.

Vipriya is a cross platform mobile app.

Algorithm Used

We extract the most-listened-to tracks, artists, and genres of each user who has signed up for the app. Then, using this data, we calculate the Sørensen-Dice Coefficient formula between each possible valid couple in our user database and apply the appropriate bias between tracks, artists, and genres. The Sørensen-Dice Coefficient measures the similarity and diversity of sample sets. It can be seen as the percentage of overlap between two sets, which is a value between 0 and 1, representing how similar the music taste of two individuals is.

API Overview

1. Spotify API

Our algorithm leverages the Spotify API for requesting top the following

  • top songs
  • top artists
  • calculating genres from the above

2. Profanity Filter API

The app uses the profanity filter to prevent any unwanted malicious words from being used in people's dating profiles (for example, their bio). The API returns the string to mark the word with asterisks.

How To Use

Mobile App

  1. Clone the repository
  1. Install the dependencies using yarn install or npm i
  1. Download the Expo Go app on your phone
  1. Create a development build for the app (https://docs.expo.dev/develop/development-builds/create-a-build/)
  1. This should install the app. The app should install on your phone.
  1. Run the client using yarn start

Backend API

  1. Run a MongoDB instance.
  1. Add the MONGO_URI to the .env file.
  1. Install dependencies using npm i
