Our Mobile App Development Process
At HBOX Digital, we turn ideas into powerful mobile experiences. Our process is transparent, collaborative, and designed to deliver a polished product that exceeds expectations—every step of the way.
Idea Discovery & Consultation
📌 Start with your vision.
We begin by understanding your app goals, business objectives, and user needs. This helps us shape the scope, features, and foundation of your mobile application.
Planning & Blueprinting
📌 Blueprint before we build.
We create detailed wireframes, user flows, and feature outlines to give structure to your idea. You'll get a clear picture of how the app will function and feel.
UI/UX Design & Prototyping
📌 Designing with purpose.
Our design team crafts stunning, user-centric interfaces. We build interactive prototypes so you can visualize and interact with your app before development begins—ensuring the experience is both beautiful and intuitive.
Development Kickoff
📌 Bringing design to life.
Now the real build begins. Our developers use Swift, Objective-C, Kotlin, and Java—along with official tools like Xcode and Android Studio—to turn the approved design into a fully functional mobile app.
Quality Assurance & Testing
📌 Testing for perfection.
We conduct thorough testing for bugs, usability, performance, and security. Every screen and feature is carefully checked to ensure everything runs smoothly across devices.
Beta Testing & Feedback
📌 Real users, real feedback.
We release a beta version to a select group of users. Their feedback helps us identify any last refinements and ensures the app is ready for real-world use.
Final Review & App Store Launch
📌 Launch with confidence.
Once testing is complete and you're satisfied, we prepare your app for launch. We handle the deployment process, ensuring your app meets all App Store and Play Store guidelines.
Transparent Pricing, Flexible Engagement Models
We know that each industry and each business has its own unique opportunities, challenges and objectives. That's why we have designed three hiring models to suit your budget and needs. Full-time, part-time, or on demand.
Project-Based
This is our preferred engagement model where we take complete ownership and responsibility of your project, from discovery call and kickoff to final deployment and beyond. The whole development and deployment plan is divided into three categories – Project kickoff, Front-end development, Backend development, & Deployment and maintenance.
Staff Augmentation
Perfect for startups or small agencies needing extra hands. We seamlessly integrate our Flutter app developers into your existing team to accelerate development and hit tight deadlines. Whether you’re aiming for faster time-to-market, or temporarily replacing key resources, we help you scale with speed and precision – at your preferred pace.
Consultancy
Ideal for companies and tech startups seeking expert guidance. Our consultancy model provides deep insights into your project’s strategy and development roadmap. We offer tailored advice, process optimization, and technical expertise to help you make informed decisions and overcome any challenges or roadblocks along the way.

What our clients say
HBox digital have been providing their Gold support package for just over six months and we have found them to be excellent in all respects. HBox digital have updated our Magento site to the latest version, resolved our outstanding bugs, found a cheaper hosting solution and installed a new payments system. They are easy and transparent to deal with and any additional costs are outlined before they start any work. Highly recommended.
Mark BurleyTheir communication skills and ability to complete the project within budget and timescale were impressive.
After the launch of the website, the client received feedback from customers concerning a better UX, and HBox digital Ltd. was able to update easier than before. They communicated through Campfire and had weekly updates through Zoom meetings. Overall, the team provided a good value for the budget.
Luisa Coates ThermapenGood Knowledge of Magento: HBox digital was recommended to us for their Magento knowledge which has proved to be excellent. We worked with Bowo and Vipin to migrate and upgrade our existing Magento shops to a new UK Fast server with additional features and plug ins installed resulting in a faster admin than we previously had. I would recommend HBox digital for Magento especially multiple shops.
Steve Long Merlin WorkwearHaving gone through the process of having new Magento sites brought online a couple of times now, I have to say that Dean and the team at HBox digital have made our latest project as smooth as can be possible.
From my experience, I can’t imagine that any new website is a trouble-free project. However, HBox digital have worked tirelessly to ensure that obstacles and hurdles have been dealt with as quickly and efficiently as possible. Would I recommend? I already have… Twice!
Richard Smith Niton999Great work with the team at HBox digital. They undertook our website maintenance from a previous developer and they have managed to accommodate many of our initial needs, including an upgrade to Magento 2.4.
Since then, we have overcome many more requests to improve website and shopping functionality and while I personally will not be overseeing their work anymore, I trust though that Versapak are in safe hands and that they can meet any new challenge that may arise.
Jeremy Graham VersapakOur Magento multistore was up and running on time and working as expected.
Sandra Simion our contact, gave us excellent customer support throughout the set-up process, she was immensely helpful and understanding. Sandra helped us purchase the correct modules and explained how they worked, Vipin sent us video demonstrations and advice too. [+]
Amanda YJ Europe LtdI've worked with many web agencies in the past and HBox digital certainly shine above the rest. Our account manager Bowo has been extremely attentive and pro-active, without whom we would not have been able to deploy our Magento 2 migration by the end of 2020.
We're very pleased at the hard work and patience that Bowo and the development team have put into this project, especially as we were working long hours towards the end. I look forward to continued work with HBox digital in 2021!
Laura Lam Phoenix MedicalOur website is built in Prestashop, and finding credible developers to maintain and progress the site was very difficult once we had made the decision to move on from our current developer.
Chilli Apple initially upgraded and re-themed our site to a very high standard with excellent communication throughout. We went live with the update (which was quite a major undertaking as it had not been done for some time and a lot had changed) right at the beginning of the COVID fiasco. [+]
Kieron Miller Skirting4uWe have found the dedicated development service an excellent way to quickly expand our team and give complete flexibility.
Priya has been a great asset to the team and provided valuable knowledge and ability to resolve our development requirements.
Garth Hoggins UBT (EU) LtdHBox digital has been the perfect fit for us. We needed a web development firm that we could trust to deliver on time and on cost. HBox digital has provided that..
We're incredibly pleased with the quality of work that HBox digital have produced and how receptive they've been to new design iterations. A great company to work alongside with upfront and transparent pricing and delivery. [+]
Alex Nowak WorkOutDepotWe received a great customer service from HBox digital. The team is very friendly and helpful. Highly recommended! Thanks to Nick, Seb, Vipin, Spencer and all the team!
