Mobile App Development Services

APPS PEOPLEKEEP ONTHEIR HOMESCREEN

We take mobile products from idea to the App Store and Google Play for startups and established companies, covering strategy, design, engineering and the backend behind the app with one team.

01Our Approach

We choose the platform approach after understanding your users and roadmap, because the right technology follows from the product and never the reverse.

02Overview

From first sketch to both app stores

  • 01iOS and Android
  • 02Product design
  • 03Backend and APIs

Mobile app development here means the whole product, including research, interface design, the app itself, the API and admin tools behind it, and release to the stores. It is the right choice when you have a product idea or an existing service that needs a mobile presence, and you want one accountable team instead of separate design, mobile and backend vendors.

The first decision is the approach. We recommend native Swift and Kotlin when the product leans on device hardware or platform features, and React Native when both platforms are needed quickly and the screens are conventional. Either way, we design the core flows first, test them with real users as a prototype, and build the smallest version that proves the product works.

03What We Do

Capabilities, End to End

01
Platform strategy

A recommendation on native, cross-platform or a progressive web app, based on your audience, feature list, budget and the team that will maintain the product.

02
Mobile product design

User flows, wireframes and high-fidelity screens designed for thumbs and small displays, validated as a clickable prototype before engineering time is spent on them.

03
App engineering

iOS and Android apps built natively or with React Native, with typed code, automated tests and a release pipeline producing installable builds throughout the project.

04
Backend and admin tools

The API, database, authentication and web admin panel the app depends on, so your team can manage users, content and orders without a developer.

05
Notifications and engagement

Push notifications, deep links, in-app messaging and onboarding flows planned around moments that are useful to the person, with opt-in prompts shown in context.

06
Analytics and store presence

Event tracking, funnels and crash reporting set up before launch, plus store listings, screenshots and keywords prepared so the app can be found and understood.

04In The App

Details Users Can Feel

Guided onboarding

First-run screens that get a new user to value quickly.

Push notifications

Timely messages that open the exact screen they refer to.

Offline mode

Core features available without signal, synced when the connection returns.

Secure sign-in

Biometrics, passkeys or social login backed by token-based sessions.

06How It Runs

From Kickoff to Launch

01
Discover and decide
02
Prototype the flows
03
Build in increments
04
Launch and learn
01
Discover and decide

We clarify who the app is for, what it must do first and how success will be measured, then recommend native or cross-platform development and write a proposal with scope and timeline.

02
Prototype the flows

Designers map the main journeys and build a clickable prototype you can hold on a phone. We test it with people from your audience and revise before committing to the build.

03
Build in increments

App and backend are developed together in short cycles. Each cycle ends with a build on your phone, so you judge progress by using the product instead of reading status reports.

04
Launch and learn

We run a beta, prepare both store submissions and release in stages. After launch, analytics and user feedback set the priorities for the next version, which we plan together.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
You have a product idea that belongs on phones

You know the problem you want to solve and who has it, but not yet whether to go native or cross-platform, what the first version should contain or what backend it needs. You want one team to make those calls with you and then build it.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

It depends on what the app does. Native development in Swift and Kotlin gives full access to each platform and the finest control over performance, at the price of two codebases. React Native covers both platforms with one codebase and suits apps made of standard screens and flows. We look at your features, audience split and maintenance plans, then recommend one approach in the proposal with our reasoning written down.

Sometimes a responsive web app is the better first step, and we will tell you if so. It reaches every device through a link and avoids store review. A native or React Native app earns its cost when people use the product daily, when you need push notifications, offline use, the camera or other sensors, or when presence on the home screen and in the stores matters to your business.

Yes. Most apps are only the visible part of a larger system, so we build the API, database, authentication, file storage and a web admin panel alongside the app. If you already have a backend, we integrate with it and suggest changes only where the mobile experience needs them, such as pagination or push tokens. For simpler products, a managed platform like Firebase or Supabase can shorten the work.

Plan for four kinds. Apple and Google charge developer account fees and take a commission on digital goods sold in the app. Hosting and third-party services such as maps, messaging and analytics scale with usage. The app needs maintenance each year to stay current with new operating system versions and store rules. And most products keep improving after launch. We outline these categories in the proposal so nothing arrives unexpectedly.

We start from the one job the app must do well and cut everything that does not serve it. Features are sorted into what is needed to launch, what can follow and what is still a guess. The proposal then states that first scope with a clear timeline, both of which depend on your product. Later releases are planned from real usage data, which is a better guide than speculation.
