Objective

LiStrict is an app that helps residents of Rusun BPJS Kabil (TB-2) estimate monthly electricity bills in real time. By inputting appliances, usage duration, and frequency, users can instantly calculate costs, making it easier to track, manage, and save on electricity consumption.

Responsibilites

Implemented the front-end in SwiftUI, including onboarding, device list, input forms, calendar picker, and summaries. Built dynamic components for adding devices with usage details, developed visual cost breakdowns with charts, and translated Figma designs into responsive, interactive UI.

Results

Delivered a fully functional prototype that allowed residents to calculate their electricity bill in advance, with estimation accuracy reaching nearly 90%.
