The Opportunity

Problem

College students are frustrated by high fees on student banking apps that lack built-in tools for easily splitting rent and utilities with roommates.

Solution

DormDivide uses past data to predict fair utility splits based on room usage. Create recurring bills for rent, track uneven shares like AC or WiFi, and settle via any app. Built exclusively for college roommates to avoid fights over 'who used more'.

Target Audience

College students living with roommates who manage shared rent and utilities

Differentiator

AI-driven unequal splits from usage logs (manual input now, IoT future), dispute resolution voting.
