Mobile Development
An app that survives the second week.
Most enterprise apps get installed once and buried in a folder. We build mobile products around a job people genuinely need done on a phone — fast, offline-capable, and worth opening again.

The problem
The app exists because someone said the company needed one.
It wraps the website, needs a connection to do anything useful, and asks for a login before showing any value. Field teams keep using paper because paper works in a basement. The build cost was real; the usage never was.
What it costs you
- Features ported from desktop that make no sense on a phone
- Anything meaningful failing the moment connectivity drops
- Two separate codebases drifting apart release by release
- Release cycles measured in months because of manual QA
- No instrumentation, so nobody knows which features are used
What we build
The parts that make it survive production.
Every engagement includes all of this. None of it is an upgrade tier.
Native engineering
Swift and Kotlin where platform depth matters — background processing, hardware access, widgets, and genuine platform feel.
Cross-platform
React Native and Flutter where a shared core is the right economics, with native modules for the parts that need them.
Offline-first
Local persistence, conflict-aware sync and queued actions, so the app works in a basement, a warehouse or a tunnel.
Mobile UX
Thumb-reachable layouts, forgiving targets, and flows designed for one hand, bright sunlight and interruption.
Security
Certificate pinning, secure enclave storage, biometric authentication and jailbreak detection where the threat model calls for it.
Release engineering
Automated builds, staged rollouts, crash monitoring and over-the-air updates for the layers that permit them.
Device integration
Camera, scanning, location, NFC, Bluetooth and printing — handled properly rather than as an afterthought.
Product analytics
Funnels, retention cohorts and feature adoption instrumented at launch, so decisions are made on evidence.
Where it pays
Real workloads. Real numbers.
Results are drawn from production engagements and measured against a pre-engagement baseline.
Field service app
Work orders, parts lookup, photo evidence and signature capture, fully functional with no signal and syncing when it returns.
Paper forms eliminated across 900 technicians
Frontline operations
Shift handover, task assignment and incident reporting designed for gloves, noise and a two-minute window.
Reporting compliance from 54% to 96%
Customer self-service
Account, billing, scheduling and support in one app with biometric sign-in and push that people did not disable.
Call centre volume down 33%
Clinical companion
Medication adherence, symptom logging and care-team messaging built to HIPAA requirements end to end.
71% weekly active use at six months
Warehouse scanning
High-throughput barcode workflows with sub-second scan-to-confirm and hardware scanner support.
Pick accuracy up to 99.7%
Executive dashboard
Secure mobile access to operating metrics with offline snapshots and device-level attestation.
Daily executive engagement up 4.4x
How it runs
From first conversation to running system.
- 01Phase 1
Find the mobile job
Shadowing real users in their real environment. Half of mobile scope dies here, correctly — desktop work does not become useful by shrinking.
2 weeks
- 02Phase 2
Prototype on device
Interactive prototypes tested on the actual hardware your users carry, not a simulator on a fast laptop.
2–3 weeks
- 03Phase 3
Build and harden
Engineering with device-lab testing, offline scenarios, low-end hardware benchmarks and security review before submission.
10–16 weeks
- 04Phase 4
Launch and iterate
Store submission, staged rollout, crash and adoption monitoring, then a release cadence driven by usage evidence.

Technology
Chosen by evaluation, not by preference.
We build on what fits your constraints and what your team can maintain. Nothing here locks you in.
- Your repositories, your cloud account, your licence
- No proprietary runtime you have to keep paying for
- Documentation written for the engineer who inherits it

How we price it
Three ways in. A stop point at each one.
Mobile is quoted per platform against a defined feature set. A shared core across iOS and Android typically reduces total cost by 30–40% where the product allows it.

Questions
What buyers ask about mobile development
Direct answers, including the ones that are inconvenient for us.
Still deciding?
Send the question to a senior engineer instead of a form. You will get a straight answer, and a no if that is the honest one.
It depends on what the app has to do. Heavy hardware use, background processing or genuine platform-idiomatic feel favours native. Forms, data and content-driven products favour a shared core — usually 30–40% cheaper with no meaningful user-visible difference. We decide during product definition with your specific feature list, not by preference.
If anyone will use this in a warehouse, basement, vehicle, hospital or rural site, then yes — and building it in later is far more expensive than designing for it from the start. If the app is purely for connected office use, we will skip it and say so.
We manage submission end to end and design against the guidelines from the first sprint, which is where most rejections are actually avoided. Where a rejection happens we handle the appeal. Typical first-review turnaround is one to three days on both stores.
We audit before recommending. Sometimes the right answer is incremental modernisation of what exists; sometimes the codebase is costing more to maintain than to replace. We will show you the maintenance cost curve either way rather than defaulting to a rebuild.
A physical device lab for the models your users actually carry — including the three-year-old mid-range Android that most testing ignores — plus cloud device farms for breadth and automated UI tests in CI.
Yes. Mobile is usually the easiest integration surface because we build a purpose-fit API layer between the app and your systems rather than forcing the app to speak to a legacy platform directly. That layer also gives you caching, versioning and a security boundary.
