Need an app built around the way your business works? See our custom mobile app development.

Every app project includes a written scope and fixed price, design and development, testing before launch, help with publishing, and a support period after launch set out in your quote.

Need more than an app? We also offer website design, SEO services, Google Ads and hosting and maintenance.

Features we can build into your app

Accounts and logins

Customer or staff accounts, so people see their own orders, bookings, rewards or records when they sign in.

Bookings and ordering

Appointment booking, order ahead and Click & Collect, planned around how your business takes bookings and orders today.

Payments

Payment integrations, so customers can pay for orders, bookings or services inside the app.

Push notifications

Send offers, reminders and updates straight to the phones of people who have the app.

Loyalty, Wallet passes and QR codes

Digital stamp cards, Apple and Google Wallet passes and QR scanning at the till, as we built for Bob & Berts.

Dashboards and integrations

Admin dashboards and reporting where you need them, and connections to your website, EPOS or other systems you already use.

How an app project works

The same four steps we use on every project.

Tell us about your app idea

What the app needs to do, who will use it and how it fits with your business. If a smaller or different option suits you better, we will say so.

Get a fixed price

You receive a written scope and a fixed price before any work starts. The price only changes if the scope changes.

Stay involved as we build

You review the app at agreed points and get progress updates, so you always know what happens next.

Launch and keep improving

We test before launch and help with App Store and Google Play publishing. Afterwards we can host and maintain the app for you.

Questions about mobile app development

How much does a mobile app cost?

Every app is quoted individually, because the cost depends on what it needs to do. After a conversation about your idea, you get a written scope and a fixed price before any work starts, and the price only changes if the scope changes.

Do you build for iOS and Android?

Yes. We build for both, and we will recommend whether one cross-platform app or separate iOS and Android apps suits your project.

How long does it take to build an app?

It depends on the features. Your written scope includes the expected timetable, so you know the plan before any work starts.

Will you publish the app to the App Store and Google Play?

Yes. We prepare the app for submission and support you through App Store and Google Play publishing.

Can the app connect to my website, EPOS or booking system?

In most cases, yes, where the system allows it. For Bob & Berts we built a bespoke EPOS integration so loyalty stamps update in real time at the till.

Can you build an app with AI features?

Yes. The SafeSite Companion app uses an AI question-and-answer layer grounded in recognised industry guidance, with a reporting dashboard for managers.

Do you host and maintain apps after launch?

Yes. Your quote sets out the support period after launch. After that we can host and maintain the app, as we do for Bob & Berts. See our hosting and maintenance plans.

Do you only work with businesses in Belfast, Glasgow and Liverpool?

No. Belfast, Glasgow and Liverpool are the cities we focus on, and projects run online and by phone, so we work with businesses across the UK. Our registered office is in Glasgow.

Discuss your app

Tell us about your idea, who the app is for and what it needs to do. We will come back with questions and a fixed price, not a sales pitch.

Not sure whether you need iOS, Android or both? Say so in the form and we will recommend one.

Stephen has kept me up to date every step of the way as they rebuilt my website. Very reasonable and transparent pricing. Support is excellent too. Highly recommended 👍🏻

Zeal Tax

Stephen and the team at Juggernaut couldn’t be more helpful. Nothing is too much trouble and their knowledge and expertise are invaluable. They have helped us get our website and Google adverts where we need them to be to increase lead generation and conversion. Without their specialist skills, we wouldn’t have known where to start! Couldn’t recommend them higher.

Elaine Smyth

Stephen has been a wee friend of mine on LinkedIn for years… starting my own business in December there, in great timing he reached out. I watched him over the years work an employed job to acing it on his own. Since he reached out he rescued me from the pain of computers that I cannot relate to and helped not only build a beautiful because but aid in building my business. He’s been a friend, a wealth of knowledge and a constant support. I couldn’t recommend a better person for the job!! Thanks my wee pall

Graham Burden

Stephen and the team at Juggernaut have built me a new site for my PAT Testing business. From start to finish the service has been second to none. Great comms I was kept in the loop and asked before they made any major decisions. The site went on there system so I could see the layout and ask for any changes which were carried out with ease. Very happy with the site and I highly recommend them.

Kev Chesters

Such a simple and smooth process. Fantastic communication throughout. Responsive and excellent service.

Sammi

After a very stressful and difficult experience with the first build of my website, Juggernaut Technologies completely restored my faith in the industry. From the very beginning, the team took the time to truly understand my vision, my business, and most importantly, my customers. They didn’t just build a website — they created a platform that feels perfectly aligned with Branded by Sammi and exactly what I needed to move the business forward. Nothing was ever too much trouble, and their communication throughout was exceptional. I was kept updated every step of the way, and for the first time in this process, I felt genuinely valued as a customer and listened to. Their attention to detail, patience, and commitment to getting everything right really stood out. I’m so grateful for their support and couldn’t be happier with the final result. I would highly recommend Juggernaut Technologies to anyone looking for a team that genuinely cares and delivers outstanding results.

Pip Doherty

Super helpful service, always quick response when you need something done. Efficient and professional. Many thanks for your service.

SafeSite Companion

Stephen and his team at Juggernaut helped bring my idea to life with a fantastic app and piece of software. The software is the first of its kind in the traffic management industry, and helped us win two national highway awards in the first two weeks of launching. Cant recommend them enough.

Matthew Lewis

Stephen and the team helped me get my website up and running and also helped me with my Google Business profile as well as Setting up Google search console which I had no clue how to do and was so easy to work with them from day one. Multiple calls with Stephen and he broken it all down to make things easy to understand from the beginning. I have now began working with them on SEO and already ranking on the 1st page for some key words and now we are undertaking PPC with them. They have even got me ranking in AI prompts which we have already had leads /clients from. I couldn't thank the team at Juggernaut enough and would highly recommend them even if you have a modest budget.

William Tinsley

Stephen and the team at Juggernaut Technologies have been brilliant from start to finish. They built our Shopify website in around a month and uploaded over 500 products, making the whole process much easier than we expected. What impressed me most was how hands-on they were. They came into the shop, helped with product photos, and gave us honest advice on what would and wouldn't work online. They now manage our website and SEO, and it's great knowing everything is being looked after properly. A big thank you to Stephen, Vinny and Rohit for all their hard work and support. I'd happily recommend Juggernaut Technologies to anyone looking for a website or help growing their online presence. William Tinsley J&W Novelty Toys & Bucket Hats
