Saveit — Mzed Studio case study

Zero-based budgeting on web, iOS, and Android, with an AI composer for plain-language entries.

Overview

A zero-based budgeting app for web, iPhone, and Android that has you give every dollar a job the moment it lands.

The problem

Traditional budgeting only shows what you spent after the fact. Saveit has people with steady or variable income assign every dollar up front, so they don't run short.

What we built

• Native iOS and Android apps plus the web app, all sharing one budget in sync
• AI composer: type entries in plain language, and nothing saves until you confirm
• Mobile apps work offline and sync when you reconnect
• Recurring bills and subscriptions post on schedule, with phone notifications
• Goals with target amounts and dates, plus reports exportable to CSV, Excel, and PDF
• Multi-currency entries converted at the day's rate, and passwordless sign-in with Apple, Google, or an email code
