Software studio · product engineering

We build software products people actually use.

Covert Digital is a development studio. We take products from a first sketch to a shipped platform — web, mobile and the infrastructure underneath — and then keep building.

What we do

A development company, end to end

We're engineers and designers who ship. One team that handles product, design and code — so the thing that gets built is the thing that works.

Web platforms

Marketing sites, dashboards and full web apps built with Next.js, React and TypeScript — fast, accessible and built to last.

Mobile apps

Real iOS and Android apps from a single React Native codebase, shipped to the App Store and Play Store and maintained for the long run.

Backends & APIs

Node and TypeScript services on PostgreSQL, designed for correctness, observability and the kind of data you can't afford to get wrong.

Payments & billing

Stripe subscriptions, Direct Debit, marketplace payouts and the recurring-billing edge cases most teams discover the hard way.

Product & design

We shape the product, not just the screens — flows, data models and the design system that keeps everything consistent.

Our own products

We build and run our own software too. It keeps us honest about maintenance, support and what it really takes to ship.

How we work

Small team, full ownership.

No hand-offs between agencies and contractors. The people who design your product are the people who build it and keep it running — so nothing gets lost in translation.

  • One team across product, design and engineering
  • Ship early, iterate with real users
  • Production-grade from day one — tests, CI, migrations
  • We stay on to maintain and grow what we build
Case study
Dyno logoDyno

A club management platform, built from scratch.

Dyno is our flagship product: one platform for clubs to run memberships, events, payments and bookings, with a real mobile app members actually open. We designed and built every part of it — the member app, the organiser dashboard, the API and the billing engine.

It's a working business, not a demo: live Stripe payments, UK Direct Debit, multi-tenant clubs and a member app shipped to both app stores.

Under the hood

A real app, not a mobile-friendly portal.

Members browse and book events, carry their membership card, chat and discover new clubs — all from a native app. Organisers get a full back office on the web. Both sit on the same TypeScript backend.

PeriNet Live access-control app
Case study
PeriNet logo

A mobile app for industrial access control.

PeriNet GmbH builds perimeter-security and access-control systems for industrial sites across Germany. We designed and built PeriNet Live — the mobile app that puts every gate, door and barrier on a site into the operator's pocket.

Operators see each entry point's status in real time, open and close them from anywhere, hand out temporary mobile keys and review a full log of who went where — all over an encrypted link to the on-site Live Hub.

250devices per Live Hub — gates, doors & barriers
2app stores — iOS & Android, one codebase
0cellular modules — runs on the site's own network
24/7real-time status & push alerts
PeriNet Live architecture — phones connect through the on-site Live Hub to I/O modules on gates, doors and barriers
Under the hood

One hub, the whole site, no cloud lock-in.

The app talks to a Live Hub on the site's own network, which drives up to 250 I/O modules across gates, doors and barriers over standard Ethernet — no cellular module, no per-device SIM. We built it to stay fast and secure whether the operator is on site or miles away.
