Mobile app development services for Android and iOS
End-to-end mobile app development services — from choosing the right platform strategy through store release and the ongoing work that starts the day after launch.
- Platform strategy
- App design and build
- Backend and APIs
- Best when
- Mobile is where your users or field staff actually are, and a web workaround is holding you back.
- Not a fit when
- A responsive website would serve the same people.
- First thing you get
- A platform decision with the reasons stated, then a working build in the first cycle.
What is mobile app development?
Mobile app development is designing, building and publishing applications for smartphones and tablets, on Android, iOS or both. The first decision is platform strategy: native for the deepest device integration, cross-platform for two apps from one codebase, or a progressive web app when an app is unnecessary. We advise on that, then build, release and maintain.
The first decision in a mobile project is not a feature, it is a platform strategy. Native gets you the tightest integration with the device. Cross-platform gets you two apps for closer to the cost of one. The right answer depends on how much your app leans on hardware, how fast you need both platforms live, and who will maintain it in two years.
We will tell you which one fits your case before you commit, including the times the honest answer is that you do not need an app at all and a well-built progressive web app would serve you better.
What we build is the whole thing: the app, the backend it talks to, the release pipeline, and the crash and performance monitoring that tells you what is actually happening on your users' devices.
What this includes
- 01
Platform strategy
A straight recommendation on native versus cross-platform for your specific case, with the trade-offs stated.
- 02
App design and build
Interface design and engineering that respects each platform's conventions rather than fighting them.
- 03
Backend and APIs
The services your app depends on, built alongside it rather than assumed to exist.
- 04
Offline and sync
Apps that keep working on a weak connection and reconcile cleanly when it returns.
- 05
Store release
Play Store and App Store submission, review handling, and staged rollout.
- 06
Post-launch monitoring
Crash reporting, performance tracking, and the maintenance cadence that keeps an app healthy.
Situations we see most often
A companion app for an existing platform
Your web product needs a mobile presence for the moments users are away from a desk — checking status, approving something, raising a request.
A field or on-site tool
Staff working away from reliable connectivity, capturing data that has to sync accurately once they are back online.
A consumer product
An app where store presence, onboarding, notifications, and performance directly drive whether people stay.
Replacing a mobile web workaround
You have a responsive site people use on phones and it is no longer enough — you need native capability, offline support, or notifications.
What to know before you start
Do you need a mobile app, or would a web app do?
Not every business needs an app in the stores. If your users visit occasionally, the product does not depend on the camera, background location or Bluetooth, and discovery happens through search, a progressive web app can be installed from the browser, work offline and send notifications, at a fraction of the build and maintenance cost.
A native or cross-platform app earns its cost when users open it daily, when it depends on device hardware, or when being in the App Store and Play Store is part of how customers find you. We will tell you which case you are in before you commit.
What does an app need besides the app itself?
The screens are usually less than half the work. Most apps also need a backend and APIs, an admin panel for your team, authentication, push notifications, analytics and crash reporting, plus developer accounts and listings in both stores.
Quotes that differ wildly often differ here, because one includes this machinery and the other assumes it exists. We scope all of it explicitly, and build the backend ourselves unless you already have one we can integrate with.
How do offline use and sync work?
Field and on-site apps cannot assume a signal. An offline-first app stores what the user needs on the device, lets them keep working without a connection, and syncs changes when one returns, with clear rules for what happens if the same record changed in two places.
Designing that in from the start costs far less than adding it after users have learned not to trust the app in a basement or a rural site.
What drives the cost of a mobile app?
Two quotes for the same idea can differ several times over, usually because they describe different software. These are the factors that move the number most.
| Factor | Effect | Why it matters |
|---|---|---|
| Platform strategy | High | Native apps for Android and iOS are two codebases; cross-platform is one; a progressive web app avoids the stores entirely. |
| Backend and integrations | High | A new backend, admin panel and connections to your existing systems are often more work than the app screens. |
| Offline sync | High | Working without a connection needs on-device storage, sync and conflict handling designed in from the start. |
| Device features | Medium | Camera, location, Bluetooth and background tasks each add native work and testing across devices. |
| Payments and accounts | Medium | In-app payments, subscriptions and account management add integration and store-policy work. |
| Design depth | Medium | A fully custom design and motion system costs more than an app built on platform-standard components. |
| Store release | Low | Submission and review are predictable when privacy declarations and account deletion are handled before submitting. |

Where we have done this
Questions we get asked
01Should we build native or cross-platform?
Cross-platform suits most business applications — the shared codebase halves ongoing maintenance and the performance gap has narrowed considerably. Native earns its cost when you depend heavily on device hardware, need the newest platform features immediately, or are building something performance-critical like real-time graphics.
02How long does a mobile app take to build?
A focused first version is typically 10 to 16 weeks including design, build, testing, and store submission. Apps with offline sync, payments, or complex backend integration run longer. We scope in phases so a usable version ships before every feature is finished.
03Do you handle App Store and Play Store submission?
Yes. We prepare the listings, handle the review process including rejections, and manage staged rollout. Store review is a normal part of the timeline and we plan for it rather than treating it as a surprise.
04What happens after launch?
Mobile apps need ongoing attention — OS versions move, devices change, and stores update their requirements. We offer maintenance retainers covering monitoring, compatibility updates, and enhancements.
05Do you build the backend and admin panel too?
Yes. Most apps need an API, an admin panel and integrations with existing systems, and we build those as part of the project unless you already have a backend we can work with.
06Can you take over an existing app?
Yes. We start with a review of the code, dependencies and store listings, fix what is urgent, then agree a plan for ongoing maintenance and improvement.
