Mobile apps engineering

One codebase, both stores, no surprises at review time.

Cross-platform iOS and Android from a unified architecture — native modules where they matter, deterministic 60fps gestures, and store-review compliance handled from the first commit.

Architecture & deliverables

What you get

devicesARCH_01

Cross-platform build

One Flutter or React Native codebase producing native iOS and Android apps.

hubBRIDGE_02

Native integrations

Swift and Kotlin bridge modules for hardware, camera, geofencing and biometrics.

databaseDATA_03

Offline-first data

Local storage that works with no connection, syncing when the product needs it.

verified_userSTORE_04

Store submission

Listing assets, review prep, and a Fastlane pipeline so releases are one command.

monitoringOPS_05

Analytics & crash reporting

Firebase Analytics and Crashlytics configured before launch, not after the first bug.

published_with_changesITER_06

Post-launch iteration

A 30-day window after launch to fix, tune, and ship the first round of changes.

02 // Methodology

Our mobile engineering approach

Architecture & flavors

Project setup, build flavors, environments, and the release pipeline first.

ENV: flavor_staging / prod

Design system in code

Components, tokens and navigation built once, from the design.

TOKENS: 48px hit-target min

Weekly builds on hardware

Weekly TestFlight / Firebase distribution against real devices.

CI: TestFlight auto-push

Store release & monitor

Staged rollout to both stores, plus crash and adoption monitoring.

ROLLOUT: phased 1→100%

Our productFlutterPlay Store

Call Forwarding — free + pro flavors, live on Google Play

A one-tap call-forwarding utility we designed, built, flavored, and shipped through store review. It's the build we point clients to for what finished looks like.

FAQ

Questions

Flutter or React Native — how do you choose? expand_more

Flutter is our default: one codebase, strong tooling, fast UI. We use React Native when your team already works in React and will own the app afterward.

Can you submit to the App Store and Play Store for us? expand_more

Yes — we prepare listing assets, handle review, and set up the release pipeline. The developer accounts stay in your name.

Do you build the backend too? expand_more

If the app needs one, yes — as part of the same engagement or a separate web/backend scope. See Web development.

What happens after launch? expand_more

A 30-day iteration window is included. Beyond that, an ongoing-partner retainer covers maintenance and new features.

Have something to build?

Send a few lines about your project. We reply within one business day with an honest read.

Start a project

Not ready to commit? Book a 15-minute build-readiness call instead — leave with a rough scope, the likely risks, and the next sensible step, even if we're not the right studio.

Best for founders with a product idea, rough spec, or existing app that needs senior builders.
