I need a simple web app that helps a group of flatmates track shared expenses and work out who owes whom. It must run in a normal web browser on both laptop and phone — no login, no server, and no database. Data should just be saved in the browser so it isn't lost on refresh. Core features: Add, rename and remove members (support 3–8 people) Log an expense: description, amount, who paid, and who shares it Split expenses equally OR by custom amounts Show each person's running balance (owed vs owing) A "Settle Up" button that calculates the simplest set of repayments — the fewest "X pays Y $Z" transactions needed to clear all debts Edit/delete past expenses with balances recalculating automatically Amounts shown in NZD ($) Deliverables: the working app (files I can open in a browser and/or a live link), full source code with a short README, and a quick demo video or link showing it working. Please include up to two rounds of minor revisions. Budget is fixed at around NZD 100 — please quote your price, your timeline, and a couple of samples of similar interactive web apps you've built. I'll choose on relevant experience, reviews, clarity of your proposal, and value for money, not lowest price alone.

Hi, We’ve built similar web apps that use browser storage instead of a server, so we know how to create a fast, responsive experience without relying on a backend. We also understand the importance of a clean, user-friendly UI, and we’ve worked with designers to create fully responsive apps that look great on both desktop and mobile. In your case, we can use a lightweight framework like Vue.js or React.js to deliver a fast, modern solution. We can also add features like user authentication and server-side processing later on, if needed. Let’s schedule a 10-minute call to discuss your project in more detail and see if I’m the right fit. I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best regards, Adil

Hi I can build a simple browser-based shared expense web app that works smoothly on both laptop and mobile without login, backend, or database. The main technical challenge is keeping all member, expense, split, edit/delete, and settlement calculations accurate while storing everything safely in browser local storage. I can implement member management for 3–8 flatmates, expense logging, equal/custom split handling, NZD formatting, running balance calculation, and automatic recalculation whenever past expenses are changed. For the “Settle Up” feature, I’ll build a clean debt-simplification algorithm that converts balances into the fewest practical repayment transactions like “A pays B $Z”. I can deliver the app as plain browser-openable files or a lightweight hosted version, with clean HTML, CSS, JavaScript, responsive layout, and a short README. I’ll also include source code that is easy to review, plus a quick demo link or video showing the full flow from adding members to settling balances. Thanks, Hercules

Tracking shared expenses among flatmates without the hassle of logins or servers is a problem I've solved before — I built a similar split-expense tool and a group budget tracker, both as pure client-side single-page apps. I'll build this using vanilla HTML, CSS, and JavaScript with localStorage for persistence, ensuring it works seamlessly on both mobile and desktop browsers. For the "Settle Up" feature, I'll implement a debt simplification algorithm that minimizes transactions by netting balances and matching largest creditors to largest debtors. I can start immediately and will deliver the complete source with README, a live GitHub Pages link, and a short Loom demo — all for NZD 95, with two revision rounds included.

Hi, I can build your flatmate expense tracker as a simple browser-based web app with no login, server, or database, using local storage so data remains after refresh. I have experience building lightweight interactive web apps with HTML, CSS, and JavaScript, including calculators, dashboards, and offline-style tools. For this project, I will create a clean responsive interface that works well on laptop and phone, supports 3 to 8 members, lets users add, rename, and remove members, log shared expenses, split equally or by custom amounts, and edit or delete expenses with balances updating automatically. I will also implement the Settle Up logic to calculate the fewest repayment transactions, display all amounts in NZD, and keep the code simple and easy to maintain. The final delivery will include source files, a short README, optional live demo link, quick demo video or screen recording, and up to two rounds of minor revisions. I can complete this within 3 to 4 days and keep it within your NZD 100 budget. I would be grateful for the opportunity to build this useful tool and will gladly accept any feedback you may have. Best, Justin

Hi there, I'm interested in building your Shared Expense Tracker as a browser-based app with offline storage and no server, so it works on laptops and phones. To keep data local, I'll use browser storage (IndexedDB or localStorage) and design a responsive UI that runs purely in the client. I'll implement 3-8 member management, expense logging with description, amount, payer, and shares, plus both equal and custom split options. I'll compute running balances, provide a 'Settle Up' algorithm that minimizes transactions, and refresh balances automatically on edits, with a short README and a demo video for easy review .

Hello there, I’ve built lightweight, browser-first apps that work offline and store data locally, so you can run a shared expense tracker directly in Chrome, Safari, or Firefox without servers or logins. I focus on clean UI, reliable local storage, and responsive layouts that feel native on both laptops and phones. In past projects I’ve delivered interactive expense and group-management tools using vanilla JavaScript and modern UI patterns. I’ve implemented client-side data models, add/edit/delete flows, and real-time recalculation of balances as expenses are added or adjusted. I’ll model the data so balances update instantly when you log an expense, rename/remove members, or edit past items, with simple NZD formatting and a straightforward “Settle Up” flow to generate minimal repayments. I can deliver a complete, tested app with clear README, source code, and a short demo video. I’ll handle the build as a single developer, with a couple of minor revisions included after you review the first version. Please feel free to reach out so we can confirm clarifications and start the build. I’m excited to help you get this in your hands quickly. Best regards, Billy Bryan

Hi! The goal is to build a lightweight, browser-based web app for flatmates to track shared expenses and calculate who owes whom. The core challenge is implementing real-time expense tracking, automatic balance updates, and the “Settle Up” algorithm entirely in the browser without a server or database. I propose using HTML, CSS, and vanilla JavaScript with localStorage for persistent data, responsive design for both desktop and mobile, and modular code for maintainability. I have experience creating interactive web apps that run fully in-browser with dynamic calculations, including expense trackers, split-bill tools, and personal finance dashboards. These projects required real-time updates, intuitive interfaces, and persistent client-side storage. So I am confident I can deliver a fully functional, user-friendly expense tracker that meets all your specifications and works across devices. Do you prefer custom splitting amounts to accept decimals or only whole numbers? Looking forward to working with you. Thanks, Ravisher

Hi, I can build this for you as a clean, fast browser app that runs entirely on the client with no server and no login. I would use plain JS with local storage so data survives refresh, plus a simple layout that works smoothly on laptop and phone. The app would let you manage members, add and edit expenses, split evenly or by custom shares, show live balances and compute the minimal settle up set using a debt minimisation algorithm. You would get the full source, a short README and a quick demo video, along with two rounds of small revisions. I can deliver in three to four days for around NZD one hundred, and I have built similar interactive tools for budgeting and small group tracking that run fully in the browser with no backend.
