App Design Agency in London

Apps. Reimagined. Fixed prices from £12,000, and a team that designs and ships.

Digiruu is an award-winning app design agency in London. We work out of 86-90 Paul Street in Shoreditch, EC2A 4NE, and we take mobile products from a first conversation through UX, UI and full development to launch on the App Store and Google Play.

Award-winning UI/UX design, done differently. Crafted by humans. Accelerated by AI. Over 30 verified Clutch reviews, a Trustpilot presence, and recognition from Clutch as a top app developer in London.

Get Started

What you get

Most agencies sell you hours. We sell you three stages, each with a fixed price and a defined output, so you always know what you are buying and what you will hold at the end of it.

You can stop after any one of them. Plenty of clients take a Blueprint, go away and raise money on it, and come back six months later for the design. That is a perfectly good outcome and we would rather you did that than commit to a number nobody has properly worked out yet.

Blueprint

Discovery, requirements and scope. We interview you and your users, map every screen and rule the product needs, and write it down as a specification any developer could build from.

You leave with a functional requirements document, user stories, a feature map and a realistic cost and timeline. If you take the Blueprint elsewhere, it still works. That is deliberate.

Design

UX first, then UI. Information architecture, user flows and wireframes come before a single colour is chosen, because a beautiful screen in the wrong place is still the wrong screen.

Then the interface: a clickable prototype of every state, a component library, motion and micro-interactions, and accessibility checked against real contrast and touch-target standards. You can put the prototype in front of users, or investors, before anything is built.

Build

Native and cross-platform development, backend and APIs, analytics, QA on real devices, and submission to both stores. We handle the review process, the rejections, and the release notes.

You get the code. You get the repository. You get an app that is yours, not a licence to something we control.

Selected work

Design is judged by what happens after launch. Here is what happened after ours.

Amore Pizzeria

A food ordering app that has taken more than 50,000 orders and helped grow the business into a multi-million pound operation. Ordering without the commission a marketplace takes.

Pretty Lavish

A fashion app for a brand with a demanding audience. Engagement rose from 30% to 80% after the redesign, because the app finally worked the way the customers already shopped.

Climate Week NYC

An event app built to a hard, immovable date, reaching 1,600 downloads across the week. Schedules, venues and thousands of attendees who needed it to work first time.

ByErim

A beauty brand app that reached a top-100 placing. Proof that a small independent label can hold its own next to companies with far larger budgets.

We have also designed Epowar for personal safety, Guava for women’s health, Stil for sleep and meditation, Refiine for sports coaching, Thrive for social work, Family Flow for parenting, Pilates on Tap for fitness, and Moblox in telecoms. The full portfolio is at Our Apps.

Pricing, in public

Three packages. Fixed prices, published, so you can work out whether to talk to us before you talk to us.

Starter — £12,000 fixed

The Blueprint on its own. Discovery, requirements, scope, and a costed plan for the whole product.

Right for founders who need to know what they are actually building, and what it will take, before committing to a full budget.

Pro — £30,000 fixed

Blueprint plus Design. Full UX and UI, a clickable prototype of every screen and state, and a design system your developers can build from.

Right for teams with engineering in place, or anyone raising on the strength of a product people can hold and tap.

Max — from £75,000

Blueprint, Design and Build. The whole product, designed and developed, tested and shipped to the App Store and Google Play.

Right for anyone who wants one team accountable from the first workshop to the first download.

Fixed means fixed. The scope is agreed at the end of the Blueprint, and the price does not move unless you decide to change what you are building. There is no hourly meter running in the background.

If you want to see how those numbers sit against the rest of the market, our guide to how much app design costs in the UK sets out the typical price bands and what pushes a quote up or down.

Why work with a London agency

We are at 86-90 Paul Street, London EC2A 4NE, a few minutes from Old Street. Shoreditch is where a large share of the UK’s app startups sit, and proximity still matters more than people admit.

Workshops go better in a room. Design reviews go better when someone can point at a screen rather than describe it over a call. When a launch date is close, being an hour away from your office instead of a time zone away changes what is possible.

It also means we understand the market you are selling into. London users have high expectations and no patience — they have already used the best app in your category, and they will judge yours against it within about twenty seconds. We design for that standard because it is the one on our doorstep.

We work with early-stage founders raising their first round and with established brands adding a mobile channel. The process is the same either way. The difference is only how much of it you need.

Being here also gives us the network that comes with it. When a project needs a specialist — a particular backend skill, a compliance question, a research participant who matches your audience — they are usually a short walk or a single introduction away rather than a procurement exercise.

And it makes us easy to check. Over 30 verified reviews on Clutch, a Trustpilot presence, and recognition from Clutch as a top app developer in London. You can read what our clients said in their own words, and several of them will take a call about it.

We would rather you compared us properly than took our word for it, so we keep an honestly ranked guide to the best app design agencies in London. It includes the studios better suited than us to certain kinds of project, and says which ones those are.

How a project actually runs

1. The first call

Thirty minutes. You describe the problem, we tell you honestly whether an app is the right answer and roughly what it would cost. Some of these calls end with us telling people not to build anything yet.

2. Blueprint workshops

A short series of sessions with you and, where it helps, your users. We pull apart the idea, find the features that carry the value and the ones that are just noise, and write the specification.

3. UX

Flows, structure and wireframes. This is where the arguments happen, and it is much cheaper to have them here than in code.

4. UI

Visual design across every screen and state, built as a system rather than a set of pictures. Empty states, error states and loading states get designed too, because that is where most apps quietly fall apart.

5. Prototype and test

A clickable build you can put in front of real people. We watch where they hesitate and change the design before it costs anything to change.

6. Build and launch

Development in visible increments, QA on real devices, then store submission. We handle App Store and Google Play review, including the rejections nobody warns you about.

7. After launch

Analytics reviewed against the outcomes we agreed at the start, and an honest conversation about what to fix, what to add, and what to remove.

Frequently asked questions

What does app design cost in the UK?

Our published prices are £12,000 for the Blueprint, £30,000 for Blueprint plus Design, and from £75,000 for Blueprint, Design and Build. Across the UK market you will see anything from a few thousand pounds for a freelancer to several hundred thousand for a large consultancy. The wide range is mostly a question of how much thinking is included before anyone opens a design tool. A cheap design that has to be rebuilt is the most expensive option available.

How long does app design take?

A Blueprint typically runs a few weeks. Design usually takes a couple of months for a first version, depending on how many screens and states the product needs. Build is the longest stage and varies most with scope. We give you a dated timeline at the end of the Blueprint rather than a guess at the start, because a guess at the start is worth nothing to either of us.

What is included in UI/UX design?

UX covers research, information architecture, user flows and wireframes — the structure of the product and the order things happen in. UI covers the visual layer: typography, colour, iconography, layout, motion, and a component library so everything stays consistent as the app grows. Both include a clickable prototype, accessibility checks, and handover files your developers can build from without guessing.

Do you build the app as well as design it?

Yes. The Max package covers Blueprint, Design and Build from £75,000, including development, backend, QA and store submission. If you already have engineers, take the Pro package and we will hand over designs and a system built for the way your team works. We are happy to sit in your sprint ceremonies during the build either way.

Do you work with early-stage startups?

Often. The £12,000 Blueprint exists partly for this: it gives a founder a specification, a costed plan and something concrete to take to investors without committing to a full design and build budget first. We have worked with founders at idea stage and with companies well past their Series A. What we look for is a real problem and someone serious about solving it.

What happens after launch?

Launch is the middle of the project, not the end. We review analytics against the outcomes agreed in the Blueprint, watch how people actually use what we made, and prioritise changes from that rather than from opinion. Ongoing design and development support is arranged separately, so you are not locked into a retainer you have stopped needing.

How do you work with clients outside London?

Comfortably. Much of our work is remote, including clients across the UK, Europe and the United States, and Climate Week NYC was delivered for an event on another continent. Workshops run over video, prototypes are shared as links, and progress is visible continuously rather than in a monthly report. If you would rather do the first workshop in person, Shoreditch is easy to reach and you are welcome.

What makes you different from other London app design agencies?

Three things. Our prices are published, so you are not put through a discovery call to find out whether you can afford us. The Blueprint is a standalone deliverable you own outright, even if you never work with us again. And we are a design agency that ships — Amore Pizzeria has processed over 50,000 orders, Pretty Lavish’s marketing messages went from being read 30% of the time to 80%. Over 30 verified Clutch reviews and recognition from Clutch as a top app developer in London, from clients who can say whether we did what we promised.

Tell us what you are building.

Thirty minutes, no pitch deck required. You will leave the call knowing roughly what your app would cost, how long it would take, and whether it is worth building at all.

Not ready for a call? Send us what you already have and we will do a free UX audit — a review of your app or website and a written document of what we found. If the product already exists and the problem is that it is underperforming, our app redesign page covers how we handle that.
