Have a product that's nearly there,but not ready for real users?

Appscot is an Aberdeen-based, UK software development company. I help businesses finish, fix and launch mobile apps, web apps and internal tools, from AI-assisted prototypes through to production-ready greenfield builds.

How I can help

AI tools, prototypes and early builds can get you surprisingly far. Production still needs authentication, APIs, payments, permissions, security, testing, integrations and a proper release process.

I help businesses take partially-built products from "almost there" to production-ready, and build greenfield mobile apps, web apps and internal tools from scratch.

Finish my app or internal tool

You've built most of it. I get it over the line with the backend, auth, integrations, cleanup, testing and deployment work needed for real users.

Fix or harden my product

It works in development, but it needs security, reliability, permissions, CI/CD, analytics or production configuration before launch.

Review my product before launch

Build from scratch

Greenfield mobile apps, web apps and internal tools, from architecture and implementation through deployment and release.

Selected Case Studies

A few examples that show startup launch, product takeover and production mobile modernisation.

Ymobile

Startup launchGreenfieldeSIM

Helped launch the UK's first eSIM-only MVNO, then led new native iOS and Android apps from scratch with white-label architecture, Stripe payments, subscriptions, biometric authentication, eSIM integration and store release ownership.

Late-stage takeoverProduction backendSubscriptions

Took over a late-stage React Native app, revamped sign-up, built admin tools, created production backend instances and CI pipelines, integrated multi-tier subscriptions and one-off purchases, then supported deployment and post-launch fixes.

Tutorful

ModernisationLive productiOS + Android

Modernised and improved a live iOS and Android tutoring marketplace, including push notification reliability, crash investigation, SDK updates, SwiftUI / Jetpack Compose migration, testing, analytics and user-facing feature work.

Technical areas I can take off your plate

You do not need to know which framework, pattern or pipeline is missing. If your product needs authentication, App Store release, backend integration, crash fixing, modernisation or production setup, I can work out what is needed and handle the implementation.

App launch and release

I can get your app through the final production steps: signing, builds, testing, store requirements and deployment.

Backend, APIs and infrastructure

If your prototype needs real accounts, permissions, data, integrations or production setup, I can handle the engineering behind it.

Mobile app modernisation

I help improve apps that have become hard to maintain, fragile to release or stuck on older architecture.

Native and multi-platform delivery

I can work across native iOS, native Android and multi-platform mobile products depending on what the product needs.

Complex mobile features

For products that need deeper mobile capability, I can work close to device hardware and specialist platform features.

Product ownership support

I can step in as the senior engineer who turns unclear technical work into a sensible plan and shipped product.
