App Development
We design and build mobile apps for NYC businesses that need a real mobile presence — not a web port. Native iOS (Swift), native Android (Kotlin), or cross-platform (React Native / Flutter). MVP shipped in 21–30 days, App Store + Play Store ready, owned by you.

How we build it
The 14-day sprint
From kickoff to production in 14 days. Here's exactly how we deploy app development — and what you'll see at each step.
Spec + UX
We spec the MVP, design the UX in Figma (clickable prototype on day 4), and lock the data model + API contract. You approve before code.
Build
We build in 1-week sprints with Friday demos. You see a working build on TestFlight / internal track by day 10. Feature-complete by day 20.
Test + polish
We run device testing (iOS + Android), bug bash, performance optimization, ASO copy, and App Store / Play Store screenshots.
Submit + launch
We submit to App Store + Play Store, handle review feedback, and ship the production launch. We support for 30 days post-launch.
