platforms, one team

A great mobile app is the outcome of clean architecture, ruthless UX, disciplined release management, and a store presence that actually ranks. We deliver all four, on iOS, Android, React Native, or Flutter.

What we ship

Everything under one roof, delivered by senior operators.

Native iOS & Android

Swift/SwiftUI and Kotlin/Jetpack Compose, for apps that demand platform-level fidelity.

Cross-platform

React Native and Flutter for teams that want one codebase on both stores.

Mobile UX

Research, flows, motion, and accessibility, designed for thumbs, not desktops.

Backend & APIs

Node, Python, Firebase, Supabase, backend infra that scales with your app.

Release & ASO

TestFlight, Play Internal, phased rollouts, and App Store Optimization for organic downloads.

Crash-free engineering

Sentry, Crashlytics, and automated E2E testing so releases ship clean.

AI in the loop

The agents that ship in every build.

The apps we ship arrive with AI baked into the product itself, plus agents inside the build pipeline so quality stays high as you add features.

agent 01

In-app assistant

Natural-language support, search, or sales inside the app, built on your own content.

triggerUser taps the assistant icon or asks a voice query.
Answer plus deep links into the right screen or flow.
agent 02

On-device personalizer

Ranks content, offers, and push notifications by user signals on the device.

triggerRuns on every session open and every key event.
Personalized feed, offer, or CTA. No data leaves the device unless you choose.
agent 03

Release QA agent

triggerRuns on every PR to main.
Screenshots, crash reports, and a go or no-go verdict.
agent 04

Store listing agent

Optimizes App Store and Play Store titles, keywords, and screenshots.

triggerRuns monthly and after every major release.
A/B tested listing with higher tap-through and install rate.
AI in the product. AI in the build. That is the only honest way to ship mobile in 2026.
How we work

A four-stage cadence that compounds every sprint.

01

Define

Product spec, user flows, and KPIs, written and signed off before we code.

02

Design

Prototypes your users can tap before engineering starts.

03

Build

2-week sprints with TestFlight/Internal builds every release.

04

Launch & grow

Store submission, ASO, post-launch maintenance, and iteration.
