Roommates

• 

  Add expenses here!

• 

  This is where IOUs are calculated.

• 

  How each expense is saved.

Inspiration

I was inspired to create this app because I will be going to college soon. I know that college is stressful, and I thought about ways to improve and simplify college life. One thing that came to mind is expenses and sharing, so I created this app.

What it does

My app allows roommates to enter their expenses and then it calculates what everyone owes.

How I built it

I used JavaScript in the AppLab environment, so that I could easily create both the frontend and backend part of the app. I used the built-in persistent data store to save expenses.

Challenges I ran into

At first, I couldn't decide on a way to store the expenses. I researched a lot and figured out how to use persistent storage to save data even once the app is closed.

Accomplishments that I'm proud of

My app tries to minimise the number of transactions between roommates. It took a lot of tries to finally get that piece of my code working.

What I learned

I really like creating apps that are simple to use, but actually help people. I also like doing hackathons because they are so much fun, and I like the challenge.

What's next for Roommates

I want to come up with a better formula that minimises the transactions even more, and I have an idea for how to do so.
