How to put together a Mobile App Requirements Brief

Whether you’re a startup with an original idea, or a large corporation looking to simplify daily tasks for
it is essential that each and every project starts with an App Requirements Brief. For app
developers such as ourselves, there is nothing more frustrating than a brilliant idea that hasn’t been thought
through logically. We understand that users seek fast digital solutions that fit into their daily lives, therefore
it is important to consider all the features of your app and their functionalities before the development process
begins. A clear App Brief makes the development process much smoother as it gives us a greater understanding
of requirements to ensure your app reaches its full potential once it is live in the app stores. This article outlines
all the areas that must be thought through carefully when putting together your App Brief.

Remember; the clearer your App Brief, the quicker we can work on turning those requirements into a
reality to help your business achieve its long-term goals.

Focus on Solving a Problem                                                                                          

The main purpose of building an app is to overcome a problem and make business processes more efficient.
Hence, clients should be prepared to share where their strategies are disjointed, so we can work with them
to bridge this gap and enhance enterprise mobility management (EMM). The power of apps lie in their capability
to connect people and share intelligent data, therefore it is important that you pinpoint what area of your
business would thrive most with these improvements. For example, Johnson & Johnson realized that printing a
monthly catalogue was outdated, so they replaced it with a digital version that saved paper and allowed their
users to interact. This has been a massive success as they can now gain valuable data insights of client activity
on the app, and use this to make their marketing campaigns much more effective. This is a classic example, so
don’t worry if your problem is completely different. As long as it can be solved with a digital solution, your app
will succeed.

Research your Target Market                                                                            

With competition tougher than ever before, it is key that your app is aimed at a target market. The more you
know about your potential users, the more effectively our developers can tailor your app to their needs. This
requires serious research on demographics. Make sure to know the location, age, and sex of your users as the
tone of your app will depend on these factors. Also, think about what your users do on a day to day basis. Are
they professionals / students / singles? And what is it that this group of people are looking to gain from using
your app? As experienced developers, we know that the look and feel of your app is just as important to users
as the service it offers. Therefore this is a major part of your app brief that will play into the design and
determine the language that is used for your app.

Choose your platform carefully                                                                         

Within the development process, choosing the right platform is a crucial decision that can enhance your app’s
purpose and functionality. There are four coding methodologies you can choose from, these being: Native iOS/
Android development, HTML5 development, Hybrid development (Native and HTML5), and a Web version.      

Native iOS/Android apps are specific to the platforms they are developed on. This means that they use the
development tools and language that the given platform supports, such as
Xcode and Objective-C for iOS.
Consequently, we recommend that if your app requires the use of complex features that use the phone’s native
functionality (e.g. Camera), this is the best option for you. This platform is the fastest, most responsive with
graphics, and provides the best overall user experience. However, it is the most expensive development option.

HTML5 apps are cross platform apps. This means that code can be reused and opened across any browser or
device. If your app is more simple and content-based (e.g. BBC News), we suggest using this platform as it is
significantly cheaper and faster to develop.         

Hybrid apps are a mix of Native iOS/Android and HTML5 development. They are typically described as
web apps and take a highly skilled design and development team to create a seamless user experience. Once
done well, it can be hard to tell the difference between a Hybrid app and a Native app, thus it is the second most
expensive development option.

A Web version of your app is also a development option to consider. If your app is targeted at consumers then
maybe this is not a priority. However, if it is targeted at business users you may want to have this. Your web
version may be a simplified version of your app, to make steps like registration, forms and payments clearer on
a desktop.

Core Features

Describing the core features is the most important part of your brief, as this will outline the basic functionalities
of your app. Think through the whole user journey from start to finish. What screens will your app have and
what are their specific functionalities? Where will your buttons be on the screen and where will they lead to?
And how many screens are there altogether? Consider what will be the most efficient experience for your user,
and make your choices based on this. If you can provide your developers with wire frames or visuals, this would
be a huge help. If not, your UX/UI designer can help you with this in the design stage, but it is always useful to
include in your App Brief if possible.

Have a Design Idea                                                                                               

Having a design in mind is always beneficial so that your UX/UI designer has something to work with. You want
to create the right look and feel for your app, so make sure to consider what will be most appealing to your
target audience. If you’re a company, you may want to use your existing brand colors and font for consistency.
However, if you’re a startup, this is a new and exciting stage that calls for a creative flare. Yet again, research is
key; If your app is aimed at professionals, maybe dark colors and formal language is best? / If your app is
aimed at students, maybe light colors with casual language is best? (One way of gaining inspiration and showing
you developers what you want is looking at other similar apps you like the design of.)


It is also important to consider where the content for your app will be sourced. Will you provide this? Or will the
information be provided by a third party? And if so, do you have copyright to the material? It is important to be
aware that images searched through google are often subject to copyright. So it may be best to use an image
libraryif you require stock images for your app. RSS feeds are a common source of content and are normally
free to use within your app. If your content is coming from an existing website, you will need to provide an API
to enable the app to display this content.

Budget & Time-frame

Having a realistic budget for your app is essential. Depending on how complex your app is, the price can vary
drastically. Most app projects require a backend system to manage the data within the app, as well as a Native
iOS and Android app build. In addition, when you consider the design work, testing, and project management,
a typical app might have a team of 7-10 people working on its development at any given time. Bearing this in
mind,it is understandable that app projects often cost an excess of $20,000. Furthermore, although it is
possible to develop an app quickly, it is more important to get the user experience and the design right before
any coding starts. This phase might take 4-6 weeks in itself. When you add the development and testing phases,
we find that most app projects take 3-6 months to complete.

Social Connections                                                                        

Another part of your brief should include Social Connections. This means deciding whether or not you would
like your users to have the opportunity to log in to your app using Facebook, Twitter, LinkedIn or other social
media platforms. A major part of your app’s success depends on how easy it is to register, share and connect
with others, so this is a popular option that is often forgotten in the App Brief!

3rd Party Integrations and API’s                                    

If you are a company with an existing database, you may want to consider connecting this to your app. An API is
typically defined as a set of Hypertext Transfer Protocol (HTTP) request messages, which is usually in an
Extensible Markup Language (XML) or JavaScript Object Notation (JSON) format. All APIs are hosted on a secure
server, with a SSL certificate to ensure all data is encrypted as it travels from the app to the backend. All APIs
have token based authentication to ensure the highest level of security. Red C have extensive experience of
developing and working with REST (JSON) and


Different apps have different security requirements. Broadly, the more security required, the more expensive
the app will be to build and maintain, however, there are a number of practices we employ as standard when
setting up systems with user accounts, passwords & general server security. For new apps/systems, we advise
using third party services to take care of any information or process which requires a high level of security. This
reduces the riskto the app owner and reduces the initial systems administration burden. Key examples of this
are using drop-in solutions for payments like Paypal or Stripe. Using these integrations means that no financial
data about the customer will be stored on your server, and therefore you can be confident that your customer’s
data is secure without having to ensure your system is fully PCI compliant.
