Project Overview
The 30-second summary
The founder of Budget Wise needed a fast, clean, and opinionated personal finance app to hit an announced social media launch date. We handled the end-to-end process, designing the UI, building the SwiftUI codebase, and securing App Store approval in 29 days.
See our mobile app development →A strict social media launch deadline with regulatory hurdles
The client came to us with a rough Figma sketch, a banking API key, and an unmovable 4-week deadline promised to their social media audience. The core hurdle was executing a rapid build while maintaining the high-security standards required for fintech data and passing Apple's strict financial app review process on the first attempt.
Native SwiftUI build focused strictly on core utility
We limited the version 1 scope to five essential screens: onboarding, dashboard, transaction tracking, category breakdown, and monthly summaries. By building natively in SwiftUI, utilizing a lightweight Node.js backend on Railway, and integrating biometric authentication on day one, we delivered a secure, high-performance app that passed review with zero rejections.
How We Did It
A week-by-week breakdown
- 1
Week 1
Design Sprint & Scoping
Ran a 2-day design sprint to lock down user flows for the 5-screen MVP. Cut all non-essential features to focus the dashboard on a single monthly net position, turning around final clickable Figma prototypes for sign-off by Friday.

Week 2-3
Native Development & Security
Built the frontend using SwiftUI and the backend using Node.js on Railway. Implemented Face ID, Touch ID, and local data encryption immediately. Rolled out continuous TestFlight builds every three days for direct founder testing.

Week 4
QA, Compliance & Submission
Completed end-to-end optimization, generated store assets for all five required device sizes, prepared financial data privacy disclosures, and submitted the build. The app cleared review and went live on day 29.
