Flutter mobile apps

Flutter apps built for iOS and Android

TechZone Services builds cross-platform mobile apps with Flutter, so one codebase runs on both iOS and Android. We handle screen design, app logic, Firebase or API connection, testing and App Store and Google Play submission, then support the app after release.

What we build

Cross-platform mobile apps from one shared codebase

Mobile app development covers everything between an idea on paper and an app your users download from the App Store or Google Play. We use Flutter, Google’s open-source UI toolkit, to build one codebase that runs on both iOS and Android. That means one team, one set of features to test, and consistent behavior across phones and tablets.

As a mobile app development company in Pakistan working with startups, small businesses and larger teams abroad, we handle the full build: screen design, app logic, backend connection, testing and store submission. You get a working app, the source code, and a clear plan for updates once real users start giving feedback.

Challenges we solve

What stops a good app idea from launching

Most app delays trace back to a few avoidable decisions about platforms, design, data and store readiness.

Paying for two separate apps

Building native iOS and Android apps separately doubles the code, the testing and the bug fixes, and the two versions often drift apart over time.

An app that feels unfinished

Screens designed without real user flows lead to confusing navigation, cramped layouts and forms that people abandon halfway through on a small screen.

Backend and data left vague

Login, payments, push notifications and stored data all depend on a backend. When that part is planned late, the app tends to struggle once real users arrive.

Rejected at app store review

Apple and Google both review apps before listing them. Missing privacy details, broken sign-in or unclear permissions can send a finished app back for rework.

Our approach

How we plan and build your app

We start by mapping the screens, user roles and data your app needs, then agree on what belongs in the first release. Design comes next, as clickable prototypes you can try on your own phone. Development runs in short cycles with test builds shared through TestFlight and Google Play internal testing, so you see progress on a real device instead of in a status report.

What's included

What our mobile app service includes

Everything needed to take an app from first sketch to a live listing, and to keep it working afterward.

Flutter app development

We write your app in Flutter and Dart, structured with clear state management so new features can be added without rewriting existing screens.

Cross-platform iOS and Android

A single codebase produces both apps, while we still respect each platform’s conventions for navigation, permissions, gestures and system dialogs.

Mobile UI and UX design

We design thumb-friendly layouts, readable type and clear flows in Figma, then test them as prototypes before any development time is spent.

Firebase and API connection

We connect your app to Firebase for sign-in, databases and push notifications, or to your existing REST or GraphQL APIs when you already run a backend.

App store submission support

We prepare store listings, screenshots, privacy disclosures and signed release builds, then respond to review feedback from Apple and Google.

Ongoing app maintenance

After launch we fix bugs, update packages, keep up with new iOS and Android versions, and ship small improvements based on user feedback.

Why it matters

Why businesses choose TechZone for apps

01

One team, both platforms

The same developers own the iOS and Android versions, so fixes and new features ship to both stores together.

02

Design and code together

Our designers and Flutter developers work from the same Figma files, which keeps the finished app close to the approved screens.

03

You own everything

Source code, store accounts, Firebase projects and signing keys are set up under your ownership, so you are never locked in.

04

Support after launch

We stay available for fixes, operating system updates and new features, rather than disappearing once the app goes live.

How it works

From app idea to store listing

01

Discovery

We list your users, core features and integrations, then define a first release that fits your budget and schedule.

02

Prototype

We turn the approved flows into Figma screens and a clickable prototype for you to review and comment on.

03

Development

We build features in short sprints, connect the backend, and send you a new test build after each cycle.

04

Testing

We test on real iOS and Android devices across screen sizes, checking performance, offline behavior and edge cases.

05

Launch

We submit to the App Store and Google Play, answer reviewer questions, and then set up a maintenance plan with you.

Flutter apps for iOS and Android start from $500. The final cost depends on the number of screens, user roles, integrations such as payments or maps, and whether you need an admin panel. After a short discovery call we send a written scope and a quote, so you know what is included before any work starts. See our pricing.

Flutter lets us ship iOS and Android apps from one codebase, which usually reduces build and maintenance effort compared with two separate native apps. If your app depends heavily on platform-specific hardware features, we will tell you during discovery and discuss whether native code or a hybrid approach makes more sense.

It depends on scope. A focused first version with a handful of core features moves much faster than an app with multiple user types, payments and a custom backend. We share a phased timeline after discovery, and we allow time at the end for Apple and Google store review.

You do. We recommend that the Apple Developer and Google Play accounts are registered in your company name, and we hand over the full source code repository, Firebase project access and signing keys when the project is delivered.

Maintenance covers crash monitoring, security patches, SDK updates required by Apple and Google, and small changes to content or features. You can choose a monthly maintenance plan or request work as needed, and we keep a changelog of every update we release.
