App Development Services, From Idea to App Store

Glorvix delivers app development services for startups and established brands in the USA and Australia, taking iOS, Android and web apps from first sketch to store launch. Discovery, UX/UI design, engineering, testing and post-launch support sit with one accountable team rather than three suppliers.

What’s included

What our app development services include

Everything you need to plan, build, launch and grow a successful app.

  • iOS & Android apps

    Native apps built with each platform’s own languages and tools when you need top performance or deep device features.

  • Cross-platform apps

    One shared codebase for iOS and Android using frameworks such as React Native or Flutter, reducing build and maintenance effort.

  • Web apps & PWAs

    Browser-based apps and progressive web apps that can be installed on the home screen, without going through the app stores.

  • UX/UI design & MVPs

    User flows, prototypes and a focused minimum viable product that tests your idea with real users before you invest further.

  • Backends & APIs

    Secure APIs, databases, authentication, payments and push notifications, built to grow with your user base.

  • Launch & growth

    App store submission, app store optimisation, analytics and post-launch updates. See our app development pricing guide for budgets.

What do app development services include?

Professional app development services cover far more than writing code. A successful app needs a clear job to do, a design people can use without instructions, a secure backend, testing on real hardware, a launch that survives store review and a plan for the version after the first one. Skip any of those and a well-coded app can still sink without trace.

Glorvix works with founders, small businesses and established brands on both sides of the Pacific, in the USA and Australia. Most projects fall into one of these categories:

  • Customer-facing apps for booking, ordering, loyalty and account management, where the app replaces a phone call
  • Minimum viable products that put a new idea in front of real users before the full budget is committed
  • Internal business apps for field teams, inspections, stock counts and approvals, often used offline in places with no signal
  • Web apps and progressive web apps that run in any browser and need no store approval
  • Rescues and rebuilds of apps that crash, cannot be updated or were left behind by a departed developer

Because we are also a search and digital marketing agency, how people will find and adopt the app is on the table during scoping, not raised after launch. Our own clients follow their projects in the Glorvix client app, so the gap between a demo and daily use is something we think about constantly.

Is an app the right investment for your business?

A good partner should start by asking whether you need an app at all. Mobile development is a serious investment, and a fast, well-built mobile website is often the smarter answer. Work through these questions before commissioning anything:

  • Will people use it repeatedly? Apps earn their place through frequency — reordering, bookings, loyalty, account management, daily tools. For a once-a-year purchase, a mobile-friendly website wins.
  • Does it need the device? Camera, precise location, Bluetooth, offline storage, push notifications and mobile wallets are the honest reasons to build an app.
  • Can you fund the second year? Budget for updates, support, store fees and marketing, not just the build.
  • How will anyone find it? Nobody browses the stores hoping to discover your brand. Plan store optimisation, website promotion and a launch campaign before development starts.
  • What does success look like? Pick measurable goals — bookings per month, or the share of users still active thirty days after install.

If the answers point to a responsive website or a web app instead, we will tell you, even though it is the smaller project.

Native vs cross-platform vs progressive web apps

The first significant decision is how to build. Each route has real trade-offs.

Native (iOS and Android) Cross-platform Progressive web app (PWA)
Codebase Separate app for each platform One shared codebase for both One web codebase for all devices
Performance Best possible Close to native for most business apps Good, limited by the browser
Device features Full access (camera, sensors, Bluetooth, widgets) Broad access, sometimes via native modules More limited, varies by browser
Upfront cost Highest Moderate Lowest
App store presence Yes Yes Not required; installs from the browser
Updates Store review for each platform Store review, one codebase Instant, like a website
Best for Demanding, hardware-heavy or graphics-rich apps Most customer and business apps Content, ordering and internal tools on a budget

iOS app development

Native iOS apps are written in Swift, increasingly with SwiftUI, and built in Xcode. They give the smoothest experience on iPhone and iPad and immediate access to new platform capabilities, which matters for apps built around the camera, health data, wallet passes or home-screen widgets.

Android app development

Native Android apps are written in Kotlin, commonly with Jetpack Compose, and built in Android Studio. The hard part is not the language but the range: screen sizes, manufacturer skins and hardware from flagship to budget. We test on genuinely mid-range devices, because that is what most of your users are holding.

Cross-platform app development

React Native and Flutter let one team write the bulk of an app once and ship it to both stores. For the majority of business apps this is the most economical route, and platform-specific native code can still be dropped in for the handful of screens that need it. The trade-off is a dependency on the framework’s own release cycle, which is a maintenance cost worth naming upfront.

Web apps and PWAs

A progressive web app runs in the browser, can be added to the home screen, works with a poor connection and supports push notifications on current mobile browsers. It is the right answer when store distribution is not essential and you want to ship changes the moment they are ready. For browser-based portals and dashboards, our web development services team often shares the build.

Our app development process, step by step

1. Discovery

We work out who the users are, what problem the app removes and how it makes or saves money. Together we rank features, choose platforms and agree the metrics that will judge the release.

2. UX and UI design

Designers map the journeys, produce wireframes and build a clickable prototype you can run on your own phone — the cheapest moment to discover a flow is confusing. Visual design follows your brand, with our graphic design team producing icons, illustrations and store artwork, aligned with your website design so the two feel like one company.

3. MVP scoping

Almost every successful app launches smaller than it was first imagined. We separate must-haves from nice-to-haves so you launch sooner, learn from actual usage and spend the rest of the budget on features the data supports.

4. Development

We build in two-week sprints, each ending with a build you can install and try. Code is version-controlled, peer-reviewed and documented, and priorities can change between sprints without renegotiating the whole project.

5. Quality assurance

Every release is tested on real iOS and Android hardware across screen sizes and OS versions: functionality, performance, accessibility, offline behaviour, permission prompts, and the awkward cases — a declined payment, a dropped connection mid-upload, a notification tapped while the app is closed.

6. Launch and store submission

We prepare listings and submit for review. Both stores publish detailed rules, and we design against the App Store Review Guidelines and the Google Play Console policies from the start. Two rules catch first-time publishers most often: digital goods and subscriptions consumed inside an app generally have to use the platform’s own in-app purchase system, on which each store takes a commission, while physical goods and real-world services do not. And every app must declare what data it collects through Apple’s privacy questions and Google Play’s data safety form, accurately enough to match what the code actually does.

Backends, APIs and integrations

Most apps depend on a backend: the servers, databases and APIs holding user data, processing payments and sending notifications. We design and build that layer, or connect to systems you already run.

Typical work includes accounts and secure authentication, payment processing, push notifications, content management, an admin dashboard for your team, and integrations with CRMs, booking platforms, e-commerce systems and analytics. We design the API so a future website, partner or second app can reuse it, and we plan for versioning from the first release, because an app on someone’s phone is not updated the moment you deploy — older versions keep calling your API for months.

App security and privacy

Apps routinely handle personal information, so security and privacy are designed in rather than bolted on:

  • Encrypted data in transit and, where appropriate, at rest on the device
  • Secure authentication, including biometric unlock and two-factor options
  • Least-privilege access to device permissions and backend data, requested in context so users understand why
  • Accurate privacy disclosures in both store listings, kept in step with what the app actually collects
  • In-app account deletion, which both stores expect from apps that let users create an account
  • No secrets in the app binary — keys and credentials belong on the server, because a shipped app can be decompiled

We will also flag the privacy regimes likely to apply to your users, such as the Australian Privacy Principles and the California Consumer Privacy Act. That is practical guidance rather than legal advice, so confirm your obligations with a lawyer.

After launch: maintenance and app store optimisation

Launching is the start. Post-launch support covers crash monitoring and fixes, performance tuning, updates for new OS releases and device sizes, security and dependency patching, analytics reviews to find where users drop out, and a roadmap shaped by what people actually do in the app rather than what was assumed in discovery.

Maintenance is also a condition of staying published. Both platforms expect apps to be built against reasonably current tooling and API levels, so an app nobody touches will eventually be unable to ship an update at all.

App store optimisation (ASO) decides how much of the store’s own traffic you capture. The levers differ by platform: Apple indexes your app name, subtitle and a keyword field, while Google Play draws terms from your title, short description and full description. We research the language buyers use, write the listing around it, test screenshots and preview videos, and encourage genuine ratings — which influence both ranking and the decision to install. Paired with social media marketing and the campaigns our digital marketing team runs, ASO turns a launch week into steady growth.

How much do app development services cost?

App budgets vary enormously, from a lean first release to a platform with real-time features, several user roles and a substantial admin system. The main cost drivers, in roughly the order they bite:

  1. Feature count and complexity, especially payments, chat, maps and offline sync
  2. Platforms — iOS only, Android only, both, or a PWA
  3. Backend and integrations with systems you already run
  4. Design complexity, including custom animation and illustration
  5. Security and compliance requirements in regulated sectors
  6. Ongoing maintenance, which is a recurring line, not a one-off

Every project is quoted after a free discovery call, against a written feature list rather than a vague brief. Before that call, our app development pricing guide explains typical market ranges, what each feature adds and where a budget stretches furthest.

Why choose Glorvix for app development services?

  • Scope discipline first. We help you cut the first release down to what proves the idea, which is usually the difference between shipping and stalling.

Frequently asked questions

App development FAQs

How much do app development services cost?

Scope drives the number far more than platform choice does. Payments, chat, offline sync, maps and multiple user roles each add engineering and testing, while a focused first release with one user type and one core job stays affordable. We quote against a written feature list after a free discovery call. Our app development pricing guide sets out typical market ranges before you talk to anyone.

Should I build a native or a cross-platform app?

Cross-platform frameworks suit most business apps, because one codebase serves both stores and halves the work of every future update. Native is the better call for apps leaning hard on device hardware, demanding graphics or brand-new platform features. We recommend an approach after discovery, and a cross-platform app can still drop into native code for the few screens that need it.

How long does a Glorvix app project take?

A focused first release typically runs three to six months from discovery to store approval; larger apps with complex backends take considerably longer. Store review sits at the end of that timeline and is usually quick, but a rejection means changes plus a resubmission, so we design against the store rules from the outset rather than hoping.

Do you publish apps to the App Store and Google Play?

Yes. We prepare listings, screenshots, release builds and the privacy disclosures both stores require, then manage submission through App Store Connect and the Google Play Console. We recommend publishing under your own developer accounts, with us added as a team member, so the listing and its reviews always belong to you.

Who owns the app and its source code?

You keep your content, your data and your store listings, and the repository is yours from the first commit rather than handed over at the end. Who owns the source code, and the licence terms of any third-party components in it, are written into the proposal before work begins, so nothing about the handover rests on good faith.

Do you maintain apps after launch?

Yes, and it is not optional in practice. Both platforms release a major OS version every year and require reasonably current build targets, so an app left untouched eventually cannot ship updates at all. Monthly support plans cover crash monitoring, OS and dependency updates, fixes and an agreed amount of development time.
