iOS & Android apps people keep installed.

We design, build and release mobile apps for iOS and Android — in Flutter for one codebase, or native Swift and Kotlin when the device demands it — all running on one secure API shared with your website and back office.

What we build

Apps for customers,
teams and products.

Six things we are asked to build most often under mobile apps — each one scoped, designed and engineered by the same senior team.

01

Customer apps

Ordering, booking, loyalty and account apps that make repeat business one tap away.

02

Fintech & trading apps

Wallets, portfolios, live quotes and order tickets with biometric login and encrypted storage.

03

Field & staff apps

Offline-tolerant apps for sales teams, drivers and technicians that sync when the signal returns.

04

Companion apps

The mobile side of your SaaS, ERP or portal, sharing the same users, roles and data.

05

MVPs for startups

A focused first version in one codebase, instrumented to learn what users actually do.

06

App rescue & rebuilds

Crashing, slow or abandoned apps audited, stabilised and brought back to store-ready.

Key capabilities

Everything an app needs
to earn its place.

The capabilities that separate a system you tolerate from one you rely on — included as standard, not sold as extras.

Discuss your requirements

One secure API

A versioned API layer shared by web and mobile, so balances, orders and users never drift apart.

Biometric login & 2FA

Face ID, fingerprint, device binding and tokens kept in the iOS Keychain or Android Keystore.

Push notifications

Segmented, deep-linked push via FCM and APNs, with quiet hours and user preferences.

Offline-first sync

A local queue and conflict rules so the app keeps working in basements and low-signal territories.

In-app payments

Card, wallet and local gateway payments, plus store billing where the platform requires it.

Crash & performance monitoring

Crashlytics or Sentry, ANR tracking and release health checked before every rollout.

Accessibility & localisation

Dynamic type, screen-reader labels and right-to-left layouts for Arabic and Urdu.

Store release pipeline

Signed CI builds, TestFlight and Play beta tracks, staged rollouts and review handling.

Technology

A stack your next
developer can hire for.

Proven, well-supported tools chosen for your team and your traffic — never for novelty.

Our process

How we deliver
mobile apps, station by station.

Every engagement runs the same visible route: a demo at each station, nothing hidden between them, and you can see exactly where the train is at any moment.

Case study · Trading · brokerage

Multi-asset platform, web + Android + iOS

A broker running a PHP/MySQL trading backend needed native mobile clients that share the exact same users, credentials, balances and trades as the website — without forking the business logic.

Ask about your project

Flutter gives you one codebase for iOS and Android and is our default for most business apps. We recommend native Swift and Kotlin when you need deep device features, heavy graphics or platform-specific UI. We decide with you after discovery, not before.

Yes — that is how we prefer to build. One versioned API serves the website, the apps and the back office, so a customer’s login, balance and orders are identical everywhere.

Yes. We prepare listings, privacy declarations and screenshots, manage review feedback and set up staged rollouts. Developer accounts are created in your company’s name.

It depends on screens, integrations and platforms. After a short discovery we fix a price per milestone. Many first releases are a focused MVP that grows release by release.

iOS and Android change every year. A care plan covers OS updates, library upgrades, crash fixes and store compliance, with a monthly allowance for new features.

Let’s put your product in their pocket.

Tell us who the app is for and what it must do on day one. We will come back with a scope, a release plan and a number.
