Our Approach to Mobile App Planning


Discovery and Planning Phase: This is where we get to know your business, your target audience, and your goals for the app. Our team of experts will work with you to define the scope of the project, create a roadmap, and identify the features and functionalities that will make your app stand out in the crowded mobile app marketplace. We’ll also conduct a competitive analysis and market research to ensure that your app is optimised for success.

Our Approach to mobile app design


Design Phase: In this phase, our team of skilled designers will create a visual prototype of your app, including wireframes and user interface design. We’ll work with you to ensure that the design meets your brand’s aesthetic and resonates with your target audience. Our designers will also create a user experience (UX) strategy that will make your app easy to use and navigate.

Our Approach to mobile app development


Development Phase: In the development phase, our experienced developers will turn the design into a fully functioning mobile app. Our developers will use the latest technology and best practices to create a robust and scalable app that meets all of your requirements. We’ll also conduct rigorous testing to ensure that the app is bug-free and ready for launch.

Our Approach to Mobile App Deployment


Deployment and Maintenance Phase: Once your app is ready for deployment, we’ll help you get it on the app stores and ensure that it’s discoverable by your target audience. We’ll also provide ongoing maintenance and support to ensure that your app is always up-to-date and performing at its best.

Frequently Asked Questions

At 89Ninety, we strive for transparency and honesty in all our interactions. We believe that working with a Creative Digital Marketing agency should be simple and straightforward, leaving you feeling confident in our process.

To help you better understand our services, pricing, and expectations, we’ve compiled this list of frequently asked questions. If you have any additional inquiries, please don’t hesitate to reach out to us. We’re here to make your experience with us as smooth and informative as possible.

As an agency, 89Ninety has been delivering our expert Creative Digital Marketing services since 2014 from our base in Belfast. Expanding our reach across Northern Ireland, the UK, and the United States. 

At 89Ninety, we’re a full-service digital marketing agency. Our services include Experience, Digital Marketing, Public Relations, Creative, and Strategy.

We offer customisable packages to suit the unique needs of your business. Our services can be used independently or combined for a comprehensive, integrated approach.

89Ninety, through the experience of working with a varied clientele, offers three distinct project models. 

These are Project-Based, Retainer, and A La Carte.

Project Based: At 89Ninety, our approach to individual projects is rooted in clearly defined scope and requirements. We use an iterative process that focuses on achieving specific goals, and we work closely with you to make informed decisions and distill your objectives. We support you every step of the way, using proven processes and transparent pricing to help you achieve your goals.

Our project-based arrangements are designed to deliver mutual gains, and many of our clients choose to continue working with us on a retainer basis after their initial projects are complete.


At 89Ninety, we offer monthly, bi-yearly, or yearly retainers for all of our services. This allows us to become an extension of your team and work closely with you over the long term. Our structured, timely execution and regular updates will keep you informed and involved, and our services can be tailored to fit your unique needs and goals.

Experience has taught us that retainers are most effective when they’re used to provide ongoing support after completing individual projects.

A La Carte:

At 89Ninety, we understand that flexibility is key to building strong, lasting relationships with our clients. That’s why we’re happy to provide specific services and deliver individual components that support your brand and products, even if they’re not part of a larger scope of work.

Our one-off services are contract-free and hassle-free, and there are no strings attached.

Contact our offices in Belfast and London to learn more about how we can help your business succeed with our tailored, flexible services.

At 89Ninety, we believe in transparency and honesty in all our pricing. The monthly retainer covers all our services, with the exception of biddable media spend on platforms such as Google Ads, Microsoft Ads, and Facebook Ads. This spend will be billed separately to our management fee, so you’ll always know exactly what you’re paying for. We want to make sure you have all the information you need to make informed decisions about your digital marketing strategy.

“When comparing prices from different digital marketing agencies, it’s important to consider the level of service and expertise included. A lower price may not necessarily equate to a lower level of service. Make sure to carefully review the deliverables included in the quotes you receive, and don’t be afraid to ask questions.

At 89Ninety, we pride ourselves on our transparency and honesty. We’ll always be upfront about the services and results you can expect from us. In our experience, it takes a significant amount of time and effort to achieve the best results, so be wary of agencies that quote significantly lower prices without explaining the potential trade-offs in service or performance. We want to ensure that our clients receive the highest level of service and the best possible results.”

At 89Ninety, you’ll have a dedicated team member who will act as your main point of contact and manage your account on a day-to-day basis. In addition, you may also work with one of our client strategy experts who will help develop your overall digital marketing strategy.

Depending on the project, various specialists from our team may also be involved, working on specific areas such as PPC, social media, or content marketing. We’re always transparent about who is working on your account and the roles they play, and all of our experts are 89Ninety employees. This allows us to provide a seamless and cohesive service that is tailored to your unique needs and goals.

At 89Ninety, we are a digital marketing agency with our main office in Belfast and a satellite office in London. We serve clients across the UK and location is not a barrier to working with us. While we value the opportunity to meet with our local clients in person, we also arrange regular calls and meetings with clients located further away. We believe that open and frequent communication is key to the success of any project, and we’re always happy to travel to meet with our clients for in-person meetings on a quarterly or bi-annual basis. We’re committed to providing the same high level of service and support to all of our clients, regardless of their location.

At 89Ninety, we take the time to thoroughly understand your business and its needs. We believe that this is essential in developing an effective digital marketing strategy.

To gain insight into your business and industry, we conduct interviews with you and your team, conduct research on your industry, analyse internal and external data, listen to your audience on social media, and study your competitors’ online presence. If you’re a local client, we’re also able to spend time working from your office each month to better understand your business operations.

All of this information helps us gain a comprehensive understanding of your business and its unique challenges and opportunities. We believe that this level of knowledge is crucial in developing a successful digital marketing plan that delivers results.

When you start working with us, our Belfast or London team will schedule a kick-off meeting with you and your team. This meeting allows us to gather all the information we need to create a comprehensive, 6-month digital marketing strategy. The strategy will outline the specific actions we plan to take and the dates you can expect to see results.

We believe in keeping our clients informed and involved, so we review and refresh the strategy every 6 months (or more frequently if needed) to ensure that you’re always aware of what’s happening and when you can expect to see progress. Our goal is to provide a clear, transparent plan that helps you track our progress and understand the value of our work.

At 89Ninety, our content marketing team is comprised of highly skilled writers who are dedicated to creating engaging and effective content. Before writing, we conduct thorough research using tools such as Answer the Public, Ahrefs, Google Trends, SEMRush, and Buzzsumo. We also incorporate input from you to ensure that our content aligns with your business goals and targets the right audiences.

We believe that marketing content often performs better when it’s written in a clear, jargon-free style that is accessible to a wider audience. We’re happy to provide examples of the content we’ve produced for our clients, both at our offices in Belfast and London. Contact us to learn more about how our content marketing services can help your business succeed online.

The time it takes to see results from our digital marketing efforts will vary depending on factors such as the channels we use, your competition, your budget, and the state of your website before we begin working with you.

However, as a general rule, you can expect to see an improvement in your online visibility and key metrics within the first three months of our work together. This is because the first three months are typically focused on developing a solid digital strategy and laying the groundwork for a successful long-term project.

Projects that incorporate PPC and biddable media tend to see results more quickly, as these channels can generate qualified web traffic almost immediately. Contact our offices in Belfast and London to learn more about how we can help you achieve your digital marketing goals.
