Fire Emblem: Three Houses - Unit Builder

A companion app/tool for the game Fire Emblem: Three Houses
Personal mobile app development project

In the game Fire Emblem: Three Houses, the player levels up their characters or "Units", and selects Classes and Abilities to their liking in order to advance and beat the game.

My app provides users a way to simulate building a Unit in the game, and includes information about how to achieve their builds in the game.

My motivation for creating this app was that I didn't want to make a spreadsheet or some other document to keep track of my Units, which is fairly common practice for players who have specific builds or plans in mind. The goal was to have an all-in-one resource that could be easily referred to while playing the game.

This app was initially intended to be a web app, and I started working on it in July of 2022. The web app wasn't fully completed -- I took some time to learn more about mobile app development between the time I paused work on the web app and the time I began to reshape the project as a mobile app.

Technologies

I used these technologies in making this app:

Spring Boot
MySQL
Axios
React Native + Bootstrap

Backend

The backend of the application is a Java Spring Boot application + MySQL database.

Database Management

The database uses MySQL and is hosted on ClearDB through Heroku.

Information about each Unit, Class, and Ability is stored in the database. No data from the user goes into the database - everything done on the user's end of the app is stored locally.

Data in the database can be viewed or edited through a user interface which was built with React and Bootstrap.

Frontend

The frontend of the application is a React Native application built using Expo and utilizes libraries including Axios and React Navigation.

DEVELOPMENT and Publishing

I started working on the frontend mobile app in November of 2022.

During the development period, I kept a self-imposed weekly release schedule to my internal testers, both to ensure that I continued to make significant progress on my project week-to-week and to simulate a real-life production cycle.

I published the first version of the application on the Google Play Store and the App Store in December of 2022, just before Christmas, bringing the development time of the mobile app to around one month.
