Complete Guide To Building An App From Scratch

how to make an app from scratch

If you are planning to enter the development process on your own without using any technical assistance, then there are some prerequisites that you should know:

  • The app requires a database, so you need to have to learn the basics of SQL.
  • You need to improve your CSS, HTML, and Javascript knowledge if you are going for the front-end web development.
  • For back-end development, you should go for Node.js as it is totally a Javascript-based platform.
  • If you're serious about the development then you should have to learn one of these languages Ruby, Python, PHP, Java, Go, C#.
  • For the development of native apps, you will need to know Swift (iOS) and Java( Android).

Step- 1: Pick an Idea

The very first step you need to take is to give yourself an idea that you want to nurture into a reality. It could be anything from creating a new game, building some service better than the existing one, or something totally unique. If you already have the idea, it’s great; move on to the second step! If you don't, then try to get one, or instead, pick a problem and observe what you can solve by using your skill. This is the step where the foundation of the development lies. Based on this idea, your app will take shape eventually, as the structure and path will be molded according to the idea.

Your research methodologies are going to decide the quality of your idea. Collect data, find patterns, and try to identify the business opportunities hidden in this data. Accordingly, plan your app that can bring great ROIs. This will also help you justify the cost of the development of an app.

Here are a few points that will help in mining out a great idea:

  • Organize market research to find out an app opportunity that aligns with your interest and skillsets.
  • Try to find an existing problem, plan an app that focuses on resolving this problem, and build a solution.
  • Look around and analyze what this world doesn't have and needed the most so you can develop something that will be appreciated by all.
  • Finally, when you have the idea in your mind and you know this is what you are going to build, note it down.
  • List the idea into points and try to simplify as much as you can.

Step 2- Lay Out The Functionalities

Without emphasizing the importance of app functionalities, the answer to the question of how to create an app from scratch can not be properly delivered. In this part of the process, you need to figure out the core functionalities of your app. Now, before you jump the gun there are a few things you need to remember. Defining the functionalities of the app doesn't mean adding all cool things you want to show off, you need to list down the functionalities that are necessary for the app to operate. At this stage of development, the functionalities need to be as simple as you are learning and you know everything starts simple.

List down all the basic functionalities and once down look again at those points to ask if they are really needed or not.

Here are some basic functionalities needed in an app for your reference:

  • Allow the user to create an account with a password.

  • Include “Forgot my password” for retrieving it.

  • User’s profile with information.

  • Include basic services, such as chatting, posting, or sharing, depending on the service you want to provide.

Step 3: Prepare a Design Wireframe

Just grab the pen and the paper to start drawing, yes, that's what you are supposed to do. Now, you need to lay down a physical presence of your idea or app so the development process could go further. Draw the user interface deciding how your end product will look like, however, it will not be the final product but just an idea of it. Decide which button and design should be placed where and how it should perform. Again, don't forget to keep things simple.

This sketch will represent the basic idea of your app and help you in shaping your development process further. While sketching, remember to look at it from the user’s perspective to come up with the best one.

Step 4: Construct the UI

This part of the development is quite important as you need to design the user interface flow of your app. That means you need to plan how exactly it will work for the users. By now, you must have a pretty good idea about the app’s functionalities, design, and how every button works.

You need to use all these in building a flowchart by considering all possible actions from the users. This will define how the user will interact with your app from being till the end. Keep a check on the evolving mobile UI design trends to design an app that suits the current market.

Start from the very first possible interaction that the user will make. And, work on the app until the user quits. You need to work on every minor detail. For example, on the account login page what happens when the user selects login or what will the app do if the user selects the forgot password. Design the whole chart with every possible step that users can select to move forward.

Step 5: Database Design

Now, you have also defined the workflow of your app and know what and how it will perform. With the help of step 4 of this guide to create an app from scratch, you will get to know the app’s behavior along with the user choices and all the functionalities of the app. In this step, it's time to design the database, as the functionalities need some storage space to operate. First, you need to point out the functionalities that will require a database for storing the information.

For example, while building a WhatsApp clone you need a database for information like user id, password, mobile no, chat back up, and story sharing.

In case your app has to interact or communicate with a server for information exchange, you will also need to draw a sequence diagram to understand the process for how to create an app from scratch will be carried out.

Step 6: Let's give UX to the app with wireframes

The backend works as the spinal cord for any software to work, but the look and app design are what makes it capable of interacting with the user. Now, it's time to work on the design, look, and feel by designing the UX. As you know how every function of the app works and how it will respond to the user, you can draw a visual look.

It's not similar to the app design that we have discussed in Step 3 when building an app from scratch, you don't need to draw it on paper. The UX wireframes will give your product almost a final look and you will be able to see it after finishing. For this, you need to work on wireframing and mockup tools recommended by the leading software development companies in the USA like Axure, Mockflow, Framebox, Wireframe.cc, Invisionapp, etc for designing the UX flow.

As the design and look of a software play a very important role in the app, you should start designing after conducting deep research. This will include analyzing your existing rivals and how your targeted audience wants it to be. This will also help you in giving a more user-oriented feel when building an app from scratch.

Step 7: Planning the Development Approach

So, you have successfully planned everything and you also have the perfect layout with all the required functionalities defined. Now, you have to code all the things that you have planned, but how are you supposed to code all that? Don't panic! Calm down, you will be able to do the coding too.

First, you need to understand that research will help you plan a better development approach. Divide all the things that you need to code in two categories; one, what are the unique things that you want to integrate; and, second, the functionalities that have been already used by the existing apps.

You can explore open-source codes to integrate functionalities that are already developed and available to use. This reduces the overall development time by making you focused on the USPs that you are planning for your apps.

Make sure you understand what could be taken from existing codes and what you need to build by yourself. For example, if your app requires the user to login, forget the password, sign up functionalities, you can borrow the code to implement the same from existing ones.

For now, you are learning to build an app so don't rush into the complicated functions.

As a beginner and don't have in-depth information about coding, you should go for the low-code app development tools. The available tools that you can use are AppGyver, Salesforce Lightning, Microsoft Power Apps, and Outsystems Platform.

Step 8: Finally, building the app

After all this tedious task of planning and designing the application, we are finally here to kickstart the development process. Now you should start developing the app with the above-prescribed considerations listed step-by-step.

Just before you press the ignition button of your app development process, there are a few things that you should know and follow when building an app from scratch.

  • Prepare a list

If you just jump into the process out of excitement without any proper plan you may end up getting confused and may forget something important. You need to prepare a to-do list from start to the end, list down all the functionalities and features one by one accordingly. This will help you in prioritizing the task that you need to perform first.

Use that list to write and implement your codes, this will help you in building the app functions step-by-step. You need to make sure that you are working on your app’s back-end as well as front-end development before moving to the next function.

  • Testing is Must

You need to ensure writing a test for each function and testing to identify possible errors and bugs. Moreover, all the pro-developers from leading custom software development companies prefer Test-Driven Development to save their time, effort, and money. Prepare a testing strategy that applies to your app.

There are plenty of app testing tools available that you can use to test your app function. You can use Jasmine and Karma for Javascript testing, PyTest for Python, PHPUnit for PHP and Rspec for Ruby, however, there are many more tools available on the web that you can choose from. 

  • Control System Tools

As you are a beginner and developing your first app, it is obvious you may encounter many mistakes during the development phase. It is advisable to use the control system with the full version of tracking capabilities. The control system will help you undo your mistakes and recover any mistakenly lost data. The most popular control systems you can use are Git, SVN, CVS and, Mercurial.

  • Extra Tips

You are in the process of developing an app that requires coding with elementary details so it quite obvious that you will have to devote considerable time and effort in your app development. But, don't worry and don’t get frustrated too, it happens to everyone, just take a sip of your coffee and follow the below-mentioned tips.

  • Google It!!

If you get stuck somewhere or you won't be able to find a bug in your function, it is suggested to Google it. You will definitely come across the solution to your problem with Google search.

  • Use information exchanging platforms

When developing an app from scratch, you'll inevitably encounter challenges and roadblocks. In such instances, information-exchanging platforms like Stack Overflow, GitHub, Reddit, and various developer forums can be invaluable resources. These platforms serve as communities where developers of all skill levels come together to share knowledge, troubleshoot issues, and collaborate on solutions.
