You have the idea and the funding. Let's put the app in your users' hands.

We design, build and launch mobile apps for iOS and Android, native or cross-platform, with a test build on your phone every week.

## Problems we solve

- Our launch date keeps slipping: Every month brings a new reason the app isn't ready.
- We don't know if we need native or cross-platform: Every agency gives a different answer, usually the one they sell.
- The app we got is buggy and slow: Crashes, bad reviews and users who never come back.
- We can't see progress until the end: No builds to try, just status emails.

## What we build

- iOS and Android apps: Native Swift and Kotlin, or React Native and Flutter
- Backend and APIs: Node.js, Firebase or Supabase backends with admin panels
- Payments and subscriptions: Stripe, in-app purchases and subscriptions
- Notifications and analytics: Usage tracking and push messages that bring users back

## How we work

- Define (1 week): We define the users, the core features and the platforms, and recommend native or cross-platform.
- Design (2-3 weeks): We design screens and flows and test them as a clickable prototype.
- Build (5-8 weeks): We build in two-week sprints with a test build for you every week.
- Launch (1-2 weeks): We handle store listings, submission and review, then watch the launch closely.

## Results

- RSA Garage: Roadside assistance app that connects drivers to nearby garages and parts vendors. Built with React Native, Node.js, MongoDB and Google Maps.
- Delivery Manager: Fleet app that works offline, sends GPS every 15 seconds, and handles driver shifts and expense receipts. Built with Flutter, Firebase, Node.js and PostgreSQL.
- Dental Clinic App, Seoul: Booking and digital records app for a dental clinic in Seoul, South Korea.

## Questions

### How long does it take to build an app?
It depends on features and integrations. The written plan you get within 48 hours of our call shows what's in version one and when it ships. You see progress every week, so the date never comes as a surprise.

### What does an app cost?
After a free 30-minute call, we send a written plan and a fixed price. If you'd rather grow a team, dedicated mobile developers start from $25/hour. If you're pre-seed and testing an idea, our MVPIn21Days program is the better fit.

### Who owns the app?
You do. You own 100% of the code, designs and store accounts. We sign an NDA before you share anything.

### What happens after launch?
We monitor crashes and reviews, fix issues and keep the app current with new OS versions. You can keep us on for support or hand over to your own team.
