TL;DR<\/h2>\n\n\n\n

\u2022 A mobile app product specification is a structured document that defines the purpose, functionality, and requirements of a mobile application before development begins.<\/p>\n\n\n\n

\u2022 The specification typically outlines product goals, target users, key features, and the overall vision of the application.<\/p>\n\n\n\n

\u2022 It also describes technical requirements, system architecture, integrations, and the technology stack needed to build the product.<\/p>\n\n\n\n

\u2022 A well-prepared specification helps development teams align on scope, reduce misunderstandings, and plan development milestones more effectively.<\/p>\n\n\n\n

\u2022 Product specifications often include wireframes, user flows, and feature descriptions to clearly communicate how the app should work.<\/p>\n\n\n\n

\u2022 Creating a detailed product specification improves collaboration between stakeholders, designers, and developers throughout the mobile app development process.<\/p>\n\n\n\n

Intro\u00a0<\/h2>\n\n\n\n

Mobile app product specification is a crucial part of mobile app development<\/strong><\/a>. <\/p>\n\n\n\n

Imagine that you got an amazing idea for a mobile application, the one that will change everything! You find a developer that will create it for you. In your mind, it\u2019s beautiful – white and blue with little bubbles all around. The user knows exactly how to use all the options<\/strong>. You\u2019re smiling – this time you thought about everything. <\/p>\n\n\n\n

And then this day comes – you can see your app for the first time. <\/p>\n\n\n\n

And\u2026 that\u2019s weird – in a way, it is your app, but it doesn\u2019t look like you wanted. It\u2019s grey and black and there are no bubbles! <\/p>\n\n\n\n

But in one thing you\u2019re right – you thought about everything. The problem is – you only thought. And no one can read your mind. <\/p>\n\n\n\n

That\u2019s why you need a mobile app product specification – to avoid situations like this. But also to be on the same page with the rest of the team, spend less time and money<\/strong> during the process and avoid the bugs. <\/p>\n\n\n\n

The key is to provide a clear picture of the scope of work<\/strong> to help the mobile app development company<\/a> make a better assessment of the time and effort that\u2019s required for the project. <\/p>\n\n\n\n

Preparing a mobile app requirements document is one of the steps in creating a perfect product. <\/p>\n\n\n\n

What is a mobile app product specification<\/h2>\n\n\n\n

A mobile app product specification is a detailed technical documentation containing information about the app features, goals, and technical requirements <\/strong>of the product.<\/p>\n\n\n\n

The main goal of this document is to provide a foundation for a successful product.<\/strong> Based on it, the entire project development proceeds and aligns the development team with the owner\u2019s vision.<\/p>\n\n\n\n

It also contains information such as acceptance criteria for the project (helpful with building a project scope), project success metrics, user requirements, and business requirements.<\/p>\n\n\n\n

A well-prepared specification prevents you from developing unnecessary functions and decreases the rework<\/strong>, which often has a huge impact on the total cost of software development. <\/p>\n\n\n\n

There are some important points that every specification should cover. <\/p>\n\n\n\n

Brief description of the app<\/span><\/h3>\n\n\n\n

A brief description is like an introduction to your app. It identifies the purpose of the product<\/strong>, the \u2018look and feel\u2019 of an app, and the main features you want to deploy. <\/p>\n\n\n\n

If you are about to work with a software house or external agency, you should cover some information about your company – what you are working on, how long are you prospering on the market and what are your main goals<\/strong>. Also, if you have any similar products or if the app is a part of the biggest project, you can describe it here. <\/p>\n\n\n\n

Then, to create a clear vision of the product<\/strong>, focus on the one problem your customer has, that your app will solve. <\/p>\n\n\n\n

The description should cover the terms and definitions of the document, and the expected time it will take to develop it. <\/p>\n\n\n\n

Also in this section, you can add all the information that you got from the market research<\/a>. <\/p>\n\n\n\n

Business context<\/span><\/h3>\n\n\n\n

To describe the business context, focus on a reason why even building mobile apps is necessary for your business, and the outcomes you expect<\/strong>. The benefits should be SMART (specific, measurable, achievable, relevant and time-bound). <\/p>\n\n\n\n

Concentrate on how your app will differentiate from other,<\/strong> similar applications, and why would customers choose yours above the others.<\/p>\n\n\n\n

It is time to define how your product will generate revenue<\/strong>. Here are some main strategies of monetization in mobile apps:<\/p>\n\n\n\n

\"Main<\/figure>\n\n\n\n

Advertisement<\/strong> <\/h4>\n\n\n\n

Earning from selling advertisement space in your app. The main benefit is that your app can stay free, so you can be sure you will have more installs.<\/p>\n\n\n\n

Freemium (Gated features) <\/strong><\/h4>\n\n\n\n

The app can stay free and have some advanced, paid features. Remember to carefully choose both free and paid features. If you offer too few features, your customers won\u2019t become engaged. If too many, users won\u2019t choose to pay.<\/p>\n\n\n\n

Premium (Subscription) <\/strong><\/h4>\n\n\n\n

In this model, the users are allowed to see some specified content, but they will have to pay to see more. One of the main benefits of this model is an automatically renewed subscription, so you will have a continual flow of revenue.<\/p>\n\n\n\n

Paid app<\/strong> <\/h4>\n\n\n\n

Those apps can\u2019t be downloaded for free, but are offered to be purchased. This is in a way, a typical form of paid services. Before you choose this model, check out competing apps – customers usually prefer to start with the free version if they have the option to use just a core feature.<\/p>\n\n\n\n

Usually, this model is chosen by recognizable brands, like Minecraft<\/a> – a popular game, that prepared a mobile version.<\/p>\n\n\n\n

In-app purchases<\/strong> <\/h4>\n\n\n\n

This model turns your app into a sales channel. You can sell both physical and digital products. It helps to make comfortable profits with the lowest amount of risk.<\/p>\n\n\n\n

In-app sponsorship <\/strong><\/h4>\n\n\n\n

Here you cooperate with ad partners who reward your users for taking specific action. It\u2019s popular in different games, like Block Puzzle Guardian<\/a>, where you can i.e. gain some more points for watching longer ads.<\/p>\n\n\n\n

During describing a business context it\u2019s crucial to set the main measurements<\/strong>, that will help stakeholders understand when your project achieves success. It can be a revenue within X months or the number of cross-sales in a chosen time. This is also a moment to get interested in different payment system options.<\/p>\n\n\n\n

The next important step is to define the business risks<\/strong> – possible situations that can badly affect your company. Estimate the probability of the risk and how it will impact the business. Once it\u2019s done, plan your actions to control, measure and mitigate the risks.<\/p>\n\n\n\n \n

User stories <\/span><\/h3>\n\n\n\n

User stories put the customer at the heart of your project.<\/strong> They are informal explanations of the features, written from the end user’s perspective. By arranging them, you can form a product roadmap that defines the features you should implement and when.<\/p>\n\n\n\n

They help developers involved in the app development process, to understand the scope of work<\/strong> and user flow. This is an essential part of software requirements specification that bridges the communication and negotiation between the development team and app owners.<\/p>\n\n\n\n

They bring many benefits to the project: <\/p>\n\n\n\n
