Mobile app development — prototypes and build-ready delivery
Prototype and build mobile apps that integrate with hardware or backends. Delivery-focused, documented and maintainable.
What this service is
— Typical mobile scope
MVP prototypes
Validate flows and value
Fast enough to show investors or test with real users. Scoped to prove the core loop — not every edge case.
Production-ready builds
Shipped, not demoed
App Store and Play Store ready. Error handling, offline states, accessibility, and performance — not bolted on at the end.
Backend & dashboard integrations
APIs, auth, data flows
REST or GraphQL, BLE, MQTT — we connect the app to whatever it needs to talk to, including hardware devices where relevant.
Not this
A demo that looks good but can't ship
A brief handed to offshore devs we've never met

Who it's for
Click a fit to see what it means in practice.
You need a mobile prototype quickly with a plan to reach MVP
We scope the fastest path to a working prototype — not a full spec. You get something testable before committing full budget.
You need an app build that integrates cleanly and is maintainable
API integrations, auth flows, and data layers built properly — not duct-taped together. Maintainable by your next developer without calling us.
You want clear scope and handover
Deliverables agreed before build starts. Source code, documentation, and a handover brief — not a repo dump with no context.
scope
We'll say so upfront if your project sits in these areas — rather than take work we're not set up for.

Problems we solve
Click a problem to see what's really going on — and what we do about it.
"We need a prototype app for users and investors."
"We need to build the MVP without creating a maintenance nightmare."
"We need clean integration with backend and authentication."
"We need predictable delivery and a clear handover."

Core deliverables
Every engagement
Mobile app codebase
AlwaysStructured repo, not a dump
Source code in a Git repo, organised sensibly with a README your next developer can follow — not a folder of files with no context.
Build instructions & environment setup
AlwaysSo others can run it
Step-by-step setup: dependencies, environment variables, build commands. Anyone on your team can get the app running without calling us.
Test notes & known limitations
AlwaysWhat was tested, what wasn't
We document what we tested, known edge cases, and anything not covered in scope — so you're not surprised when someone finds a gap.
Release / build guidance
AlwaysApp Store & Play Store basics
Basic guidance for building and submitting — certificates, identifiers, store listings. Not a full ASO service, but enough to get it live.
Handover documentation & runbook
AlwaysArchitecture, flows, open items
Architecture overview, key decisions, integration notes, and a list of open items — structured for whoever comes next.
How we engage
Three paths — hover to explore, pick based on how clear your scope is right now.
Mobile app prototype package
Bounded starting point, built for speed
You need something testable fast — prototype scoped to your core user flow, built and handed over with source code.

Milestone-based build
For MVP or production with clear scope
Scope is clear enough to agree deliverables upfront. Build staged into milestones with review gates — you see progress, not just a final delivery.
Flow

Blueprint / Audit sprint
Start here if scope is unclear
If you're unsure what to build, how long it'll take, or whether your existing codebase is salvageable — a sprint answers those questions before you commit.

Fintech MVP — onboarding, auth, and dashboard
A founder needed an investor-ready app prototype in 3 weeks — onboarding, login, and a basic dashboard pulling live data.
to TestFlight with BLE + offline
IoT companion app — BLE device control and logging
A hardware startup needed a companion app for their BLE device — pairing, real-time data display, and offline-tolerant logging.

How we keep quality high
Three things that make quality visible, not just promised. Click any to see what's concrete.
Requirements & acceptance criteria
What the app must do — agreed before build
Written requirements brief, signed off by both sides. Each screen has a definition of done — not interpreted after the fact.
Milestone delivery & review points
Progress visible — not just at the end
Each milestone ends with a working build and a review point. You can course-correct at each gate — not after everything is built.
Documentation & handover as standard
Delivered — not an afterthought
Architecture overview, API integration notes, setup instructions, and open items — written as we go, reviewed before close.
