How we approach mobile
A Phone Is Not A Small Desktop
Mobile apps need to work in real conditions, not just on a perfect connection. We design for smaller screens, slower networks and quick interactions, so the experience stays fast and reliable.
We start with the screens and map every important state before development, including loading, empty, error and offline states. This helps us build an app that works beyond the ideal user journey.
-
Every Screen, Every State
The full screen set is designed and reviewed as a flow before build starts, so nobody discovers the empty state in week six.
-
Sixty Frames Or It Is A Bug
Scrolling, transitions and gestures are held to a frame budget on a mid-range device, not the newest phone on the desk.
-
Works Without Signal
Local-first data and reliable sync keep the app usable without a connection and automatically sync changes when connectivity returns.
-
Store-Ready From Day One
App Store and Play Store requirements, permissions, privacy details and review guidelines handled throughout development.
What we build
Mobile App Development Services
From a first release that proves the idea, to a mature product shipping every fortnight.
One Codebase, Both Stores
Cross-platform app development on React Native or Flutter where the product suits it: one team, one codebase, two stores, with native modules dropped in wherever the platform genuinely matters.
- Shared codebase across iOS and Android
- Native modules where performance demands them
- One release train for both stores
- Roughly two-thirds the cost of two native builds
Native Where It Earns It
Native iOS and Android app development in Swift and Kotlin, for apps that lean on the hardware: camera pipelines, background location, heavy graphics, or the platform APIs that cross-platform wrappers keep a version behind.
- Swift & SwiftUI on iOS
- Kotlin & Jetpack Compose on Android
- Direct access to platform APIs
- Widgets, share sheets and system integrations
Buying On A Phone
Catalogue, cart and checkout tuned for a thumb: wallet payments, saved cards, order tracking and the push notifications that bring people back without annoying them.
- Apple Pay and Google Pay
- Saved payment and address books
- Order tracking and returns
- Push that is useful rather than noisy
Apps For People At Work
Tools for staff in the field: job lists, capture forms, signatures and photos that keep working underground and sync the moment there is signal again.
- Offline capture with conflict-safe sync
- Role-based access and device enrolment
- Photo, signature and barcode capture
- Distribution outside the public stores
What you can hold us to
The Standards We Build Against
Numbers agreed before the build starts, and measured on real devices rather than a simulator.
-
0
Scroll & transition target
Held on a mid-range Android, not just the newest iPhone.
-
0
Cold start budget
From tap to usable screen, measured on real hardware.
-
0
Crash-free sessions (per 1000)
Monitored per release, with alerting on regressions.
-
0
Release cadence
A build in your hands every fortnight through TestFlight and Play internal testing.
Transparent delivery retainers
Mobile App Development Pricing
Monthly retainers rather than a fixed quote against a spec nobody can hold still. Cancel with a month.

Need a one-off build instead of a retainer?
We also quote fixed-scope apps, rescue work on an existing codebase, and white-label delivery for agencies. Describe the problem and we will scope it properly.
How we work
From First Call To The Store
A structured route from idea to a listing people can download, with something on your phone throughout.
-
01
Discovery & Flows
Who the app is for, what it must do on day one, and the flows that matter, agreed as a screen map before any design work.
-
02
Screen Design
Every screen and every state drawn and clickable, reviewed on a real phone rather than as pictures on a laptop.
-
03
Build & Test Flights
Two-week cycles, each ending with a build on your device through TestFlight and Play internal testing.
-
04
Device & Store QA
Testing across a real device matrix, then privacy, permissions and review-guideline checks before submission.
-
05
Launch & Iterate
Store submission handled end to end, then crash monitoring, analytics review and the next release.

FAQ
Mobile App Questions
Still unsure? Send us a note — we reply personally.
Retainers start at $1,999 a month for a focused first release in both stores. A deeper product with user accounts, payments, notifications and a custom backend sits in the middle tier, and native builds with camera, GPS or Bluetooth work above that. Most first releases run three to five months, so budget against the total rather than per screen.
Cross-platform suits most products: one codebase, both stores, roughly two-thirds the cost of building twice. Native earns its budget when the app leans on the hardware, such as heavy camera work, background location or complex graphics, or when you need platform APIs the moment they ship. We will tell you which yours is, including when the cheaper answer is the right one.
A focused first release is typically three to five months from kick-off, including store review. You will have a build on your own phone within the first two weeks, and every fortnight after that, so you are never waiting until the end to see it.
Yes, end to end: developer accounts, listings, screenshots, privacy manifests, age ratings and the review process itself, including responding to rejections. Store guidelines are handled as we build rather than discovered at submission.
Often, yes. We start with a short audit of the codebase, its dependencies and its release setup, then give you an honest read. Sometimes the right answer is to continue it. Sometimes it is to rebuild the parts that will keep costing you. You get that assessment either way.
You do. The repository, the App Store Connect and Play Console accounts and the signing certificates are yours and stay in your name, documented at handover. There is no per-seat licence back to us and nothing that has to stay with us for the app to keep shipping.
