ISO certified

Ascensor is one of only a handful of digital agencies in Leeds to achieve ISO 27001 certification, ensuring the highest standards for website and data security. ISO 27001 accreditation gives our clients assurances that data is processed securely across all our departments, from website design development to digital marketing and accounts. We've completely ingrained ISO 27001 methodology across the entire digital agency, from physical building access control security through to delivery of services.

We pride ourselves on world-class information security - and we can prove it to our clients. Our certification guarantees that when you come to us, you're working with a web design and development agency that offers optimal site security. This means your users can have peace of mind when sharing their personal and banking data with your site.

Native app development

Traditional native apps are developed for each device platform (iOS and Android) and are coded to use the technology of the device (phone or tablet). Native mobile apps can make full use of device features - not only the hardware but potentially also stored data and contacts - and our full-stack team are experts at developing technology solutions to make your native app a complete success.

iOS and Android apps

Our design and development team create apps for both Android and iOS, and our services include submission into the App Store and Google Play Store, to ensure that your new app can be discovered by your target audience. For businesses creating apps for internal purposes, they can also be installed directly to team members' Android devices without going through the Play Store.

As top app developers, one of our main focuses has been creating non-commercial apps that enhance business processes, and we have a wealth of experience in working within the facilities management, healthcare, education and legal professions.

Progressive web app development

Progressive web apps (PWA) combine the user experience of an app with the accessibility of a website. We think they're the future. Running your applications within a mobile web browser instead of a traditional installed native app makes sense for many clients. This is where progressive web apps can thrive - the development time is quicker, costs are reduced and they're gaining more features in each browser release.

Some of the main benefits of PWAs include:

Improved performance
Faster loading times
Engaging user experiences
Reduced data use

They're accessible from any device and can generally be much more cost-effective than a native app. Progressive web apps are by their very nature mobile-first, but they also accessible via a desktop, which presents much more scope than traditional native apps, giving great user experience regardless of device.

Bespoke web app development

Our apps are coded using the latest development techniques to make the most of reduced screen size, ensuring users don't get lost within your site and can intuitively navigate your key information. Plus, our PWA development is always properly planned within the UX design process to ensure that the mobile experience meets expectations for usability.

Website development capability is evolving faster than ever, alongside mobile internet usage, and we believe that progressive web apps are the future for all website development in the coming years. We're developing more and more PWAs for businesses whose device traffic is heavily skewed towards mobile and tablet. Have you thought about a progressive web app for your next project?

Consultation & objectives

The first step in the mobile app development process is sitting down with you to fully understand what you want to achieve. During this stage of the application development project, our app design agency experts liaise with you to identify your target users, the purpose of the app, research the competition and establish the aims and objectives of your business.

Wireframe & refine

Our apps always have UX at heart, that's why we spend time ensuring that the user experience is smooth and effective to achieve your goals. Once the purpose is decided, our application development UX team will get to work on the wireframe to provide a visual structure of the app's functionality.

App build

The core app build will then start, beginning with the back-end development to support the desired functions of your app, followed by integration with any APIs or third-party systems. The next stage is to develop the front-end for your native or progressive web app and make the user interface work intuitively for the user.

Analytics & UX optimisation

As a data-driven mobile app development company, we know just how important it is to know exactly how your investment in digital products is working for you. So your project manager will take an in-depth look into the analytics of your new app and look to understand and optimise the user experience.

Ascensor have been at the heart of our approach to gaining clients once hair salons were allowed to re-open on July 4. Many salons have been quiet after the initial rush of clients coming back to have their hair cut and re-styled following lockdown. However, thanks to Ascensor’s very practical and hands-on help and advice on website enhancement, SEO and social media promotion, our team of nine stylists have been at full capacity for the last four months.

Delivering this initial project with Ascensor has introduced yet another distinctive advantage to Magnet. We have freed ourselves from a manual and time-consuming customer engagement process. This is just the beginning and we look forward to working with Ascensor on our next value-add initiative.

Alicia Kite

Founder

Working with Ascensor has made an enormous difference to how we run our business - it’s been truly transformative. We have saved so much time thanks to the automated processes we were previously doing manually. Everything is quicker, smoother and easier and our customers are enjoying a better level of service online as a result.

HubSpot is a very capable, yet complex CRM and marketing system. We’ve adopted it at Schofield Sweeney but weren’t getting the most out of it. Thanks to working with Ascensor we’ve been able to make big improvements to all our automations, including meeting sequencing, nurturing and follow-up.

Common questions

Why choose Ascensor as your app development agency?

Ascensor is an app development agency with experience across UX, software development, integrations and digital strategy. This means app projects can be shaped around user behaviour and business value, not just technical delivery. From early scoping through to build and optimisation, Ascensor can help create apps that solve real problems and support measurable outcomes.

Can an app help generate more leads or customer engagement?

An app can support lead generation or customer engagement when it gives users a practical reason to return. This might include account tools, loyalty features, booking functionality, calculators, notifications or personalised content. The key is to make the app genuinely useful rather than treating it as another marketing channel. Ascensor can help identify whether an app would create enough value for users and the business.

How much planning is needed before app development starts?

App development should start with enough planning to define users, core features, data flows, integrations, security requirements and success measures. This avoids building features that are not needed and helps prioritise a realistic first version. Ascensor uses discovery and UX planning to shape the scope before development begins, reducing risk and making budgets easier to control.

What is the difference between a native app and a progressive web app?

A native app is built for a specific operating system, such as iOS or Android, and is often distributed through an app store. A progressive web app is delivered through the web and can provide app-like features, although device access varies by browser and platform. The right approach depends on required functionality, audience, budget and long-term maintenance.

‍

Does my business need a mobile app?

Your business may need a mobile app if users need frequent access, account features, offline functionality, push notifications or a faster way to complete repeat tasks. If the requirement is mainly information-based, a responsive website or progressive web app may be more cost-effective. Ascensor can help compare the options before you commit budget to a full app build.

What does an app development agency do?

An app development agency plans, designs and builds mobile apps, web apps or progressive web apps for specific user and business needs. This includes discovery, UX, technical architecture, development, testing and launch support. Ascensor helps businesses understand whether an app is the right solution, then scopes the features, integrations and user experience required to make it commercially useful.
