GroceShare

• 

Inspiration:

Since we are living in a hostel, we understood how difficult it can be to manage shared expenses. Small things like deciding who should buy groceries or how to split the cost often lead to unnecessary arguments or confusion. Sometimes, instead of debating who should go buy items, we thought — what if we just had one shared list where everything is tracked clearly?

We realized that the problem wasn’t the money itself, but the lack of transparency. So we decided to build GroceShare — a simple solution to make shared spending organized, fair, and stress-free.

What it does:

GroceShare helps roommates track shared grocery expenses and automatically calculate each person’s share.

Users can:

Add grocery purchases

See who paid

Automatically split the cost among roommates

View balances clearly (who owes whom)

Avoid manual calculations and confusion

How we built it:

We built GroceShare as a web application.

Frontend:

HTML

CSS

JavaScript / TypeScript

The system handles:

Expense recording

Share calculation logic

Balance tracking display

Challenges we ran into:

The main challenge was designing the calculation logic correctly.

Splitting expenses sounds simple, but it becomes tricky when:

Different people pay at different times

Multiple purchases exist

Balances must update dynamically.

Accomplishments that we're proud of:

Built a working shared expense tracker from scratch

Implemented automatic split calculations

Designed a clean and understandable interface

Turned a real-life daily problem into a usable solution.

What we learned:

We learned:

How real-world problems differ from textbook problems

Structuring logic for financial calculations

Importance of UI clarity in productivity apps

Working as a team and dividing responsibilities

What's next for GroceShare:

In the future, we plan to expand GroceShare into a complete roommate expense ecosystem:

Group joining via shareable link

Direct grocery & food ordering integration

Instant split payment after purchase

Partnering with delivery platforms for offers

Notifications and reminders
