Android and iOS app development, shipped to both stores
Flutter, React Native and native builds with store submission included
An app earns its cost when the phone is genuinely the right place for the job: bookings, field work away from a desk, loyalty and repeat ordering, or a product that needs a camera and a pocket. We design, build and submit for Android and iOS, put the cross-platform versus native decision in writing, and stay on for the first month after launch.
Android and iOS app development
The first question we ask is whether you need an app at all. A fast, well-built mobile site does the job for a surprising number of the briefs that reach us, and it costs a fraction of maintaining two store listings. When the answer is genuinely yes, the next decision is one codebase across both platforms with Flutter or React Native, or fully native in Swift and Kotlin.
Cross-platform suits most business apps and roughly halves what you spend keeping them alive. Native earns its money when the app leans on the camera, AR, Bluetooth peripherals or long-running background work. That trade-off goes in the proposal, in plain terms, before you commit.
What is included
Product discovery and a clickable prototype. UI design that respects each platform's conventions rather than shipping an iOS layout to Android users. The app. The backend, or the integration with the systems you already run. Analytics and crash reporting. Store listings, screenshots and submission. Thirty days of monitoring and fixes after launch.
The developer accounts are registered to your company and the repository is yours from the first commit.
After launch
Apps are never finished. Two OS releases a year break something, dependencies age out of support, and users ask for things you had not thought of. A maintenance retainer covers that. Being found in the stores is a separate discipline, covered under app store optimisation, and you can also hire the developers monthly if you would rather build the capability in-house.
What app development includes
Product discovery & prototype
What the app is for, the screens that job actually needs, and a clickable prototype you can put in front of ten real users.
UI/UX design
One design system that still respects iOS and Android conventions, checked on real handsets rather than in a simulator.
Cross-platform build
Flutter or React Native: one codebase, both stores, and a release that goes out the same day on each.
Explore →Native build
Swift and Kotlin where the app depends on the camera, AR, Bluetooth or background processing to do its job.
Backend & integrations
APIs, authentication, payments, push notifications, and the connection to your CRM or ERP that makes the app worth having.
Store submission & ASO
Listings, screenshots, privacy and data-safety declarations, reviewer test accounts, and the conversation when Apple asks a question.

Requirementsweek 1–2
Users, jobs, platforms, integrations and the offline rules, which are the thing most briefs forget, written up as a scope you sign off.
Design & prototypeweek 2–4
Wireframes, then a clickable prototype put in front of a handful of real users before anybody writes production code.
Buildweek 4–12
Two-week sprints, each ending with a build on your own phone through TestFlight and Play internal testing.
Test & QAweek 12–13
A device matrix covering the older Android handsets your users actually own, automated tests, accessibility and performance checks.
Launchweek 13–14
Store submission, the review back-and-forth, and analytics plus crash reporting live from the first public build.
Supportongoing
Thirty days of monitoring and fixes included, then a maintenance retainer if you want one.

From $12,000/project
Cross-platform apps from $12,000; native or backend-heavy builds are quoted after discovery.
Mobile apps, answered
Should we build for iOS, Android or both?
Both, in nearly every case, using one codebase so it costs about what a single native app would. The exception is a business whose users are demonstrably on one platform, which in India usually means Android and in a US B2B product often means iOS.
How long does it take to build an app?
Twelve to sixteen weeks from kickoff to store approval for a typical business app. Simple apps go faster; anything with a custom backend or offline sync goes slower. You get a build on your phone every fortnight, so progress is visible rather than reported.
How much does an app cost?
From $12,000 for a cross-platform business app with a defined scope. Native builds, custom backends and third-party integrations push it up. You get a range in the first reply and a fixed price once discovery is done.
Native or cross-platform?
Cross-platform for most business apps, because one codebase means one fix rather than two. Native when the app depends on heavy camera work, AR, Bluetooth peripherals or background processing. We write the reasoning down so you can disagree with it.
Do you provide support after launch?
Thirty days of monitoring and fixes are included as standard. After that a maintenance retainer covers the OS releases, dependency upgrades and small improvements that every live app needs. Plenty of clients take it for a year and then run the app themselves.
How do you get an app approved by the stores?
By preparing the parts that cause rejections. Privacy and data-safety declarations that match what the app actually does, a working test account for the reviewer, and clear explanations of any permission requested. Most rejections we see elsewhere are about login flows or privacy text.
