Mobile App Development

Cross-platform Flutter apps for iOS and Android that users actually keep on their phones.

Overview

What this service covers

We build Flutter applications that deliver a native feel across iOS and Android from a single codebase. From consumer apps to enterprise tools, we handle the full cycle, Figma to App Store. Our mobile apps ship with clean architecture, offline-first data handling, and performance that holds up on real devices throughout India and internationally. We include backend API development, store submission, and post-launch monitoring as standard.

How we work

Our approach to mobile app development

We do not start building until the screen flows and designs are signed off in an interactive Figma prototype. This is the step that prevents rebuilding core screens three weeks into development because the app flow did not work as expected on a real device. Every mobile project begins with wireframes reviewed in a prototype, API contracts agreed, and architecture decisions locked before a single Flutter widget is written.

Testing on real devices runs from week one, not as a final QA step, but as a continuous part of development. We test on a range of actual Android and iOS hardware throughout the build. Performance on a low-end Android device matters as much as on a flagship, often more, and we design and test for lower-end hardware first because that is where most Indian users are.

App Store and Play Store submission is part of our delivery scope, not a hand-off point. We manage metadata, screenshots, review responses, and post-launch monitoring. App rejections are typically for metadata or minor guideline issues that we catch before submission. When a rejection does happen, we handle it, it is not your problem to manage.

Right Fit

Who this is for

Consumer app founders

Launching a B2C app and need iOS and Android coverage without the cost of two separate native teams, and a single team that owns the full product.

Businesses adding a mobile layer

You have a web product and your users want a mobile app. We add it without rebuilding the backend or asking you to coordinate two separate teams.

Field-facing companies

Your sales team, drivers, or field agents need a mobile tool that works offline and syncs when connectivity returns, a real constraint in Indian field operations.

Our Process

How we work

01

Discovery and scoping

User story mapping, screen flow definition, and API contract design before building begins. This is where architecture decisions that affect the entire project are made, it is worth doing properly.

02

UI design and prototype

High-fidelity Figma screens with interactive prototypes reviewed and approved before development starts. We do not build from low-fidelity wireframes, the prototype is close to the final product.

03

Development and testing

Feature builds with real-device testing on iOS and Android throughout the sprint. TestFlight and Firebase App Distribution for client review and early user feedback.

04

Store submission and launch

App Store and Play Store submission, review management, and post-launch monitoring. We handle all metadata, screenshots, and review communications on your behalf.

Why us

Why Plazmasoft for mobile app development

Flutter expertise, not Flutter experiments

We have shipped multiple Flutter apps across App Store and Play Store. We know the performance patterns that break under real usage, the state management approaches that scale, and the submission requirements that catch teams off guard, because we have been through them.

Backend API is not a separate engagement

Most mobile apps need a server. We build the Laravel or Firebase backend alongside the Flutter app, so you are not left coordinating two teams building separate pieces of the same product with mismatched assumptions.

We handle the stores entirely

App Store Connect, Play Console, TestFlight, Firebase App Distribution, metadata, screenshots, and review management are all handled by us. You provide requirements; we handle everything through to a live app in both stores.

FAQ

Common questions

Flutter gives you a near-native experience from one codebase, cutting build time and ongoing maintenance cost significantly. For 90% of requirements it is the right call. We will tell you the 10% of exceptions upfront, things like deep platform-specific hardware integration where native is genuinely better.
Apple reviews typically take 1 to 3 business days. Google Play is usually under 24 hours. We handle the submission and any review responses for you, rejection communication is our responsibility, not yours.
Yes, provided the existing codebase is reasonably structured. We will assess it first and give you an honest evaluation before quoting. If it is better to rewrite, we will say so and explain why.
Yes. Most mobile projects need an API backend. We build Laravel REST APIs or use Firebase and Supabase depending on project scope and your team's ability to maintain it after launch.
Yes. We set up and manage App Store Connect and Google Play Console accounts under your company name, or use your existing accounts. All credentials are yours, we never hold app ownership.
We handle review feedback and resubmit. App rejections are usually for metadata or minor guideline issues that are caught and addressed quickly. Systemic issues are caught and fixed during development before submission reaches that point.
Yes. Flutter's single codebase means both platforms are developed in parallel, not sequentially. We test on both platforms throughout every sprint, not just at the end. You receive two published apps in the same timeline as one.
Yes. Firebase Cloud Messaging for push notifications, deep linking, in-app analytics, crash reporting with Crashlytics, and remote config are standard integrations we include in most mobile app builds.
