Diet and nutrition app development: Close-up

Nowadays, mobile devices have become widely distributed and have penetrated all spheres of life. Due to this fact, almost any user has an idea of mobile applications, like diet and nutrition app development.

Really, mobile devices open up a whole new way for us to interact with computing resources, the Internet, and even corporate infrastructure.

What is a diet and nutrition app?

Modern digital technologies make weight loss more and more comfortable. Mobile diet and nutrition apps by Weelorum help users control their diet and count calories regardless of location.

If you want to create such as make sure that it can make slimming effective and fast. In the app, users can choose varying levels of difficulty. With the help of an app like this one, people can draw up their training plans.

So, pay attention to adding control options. They will help not miss the date and time of the training. In short, the described type of diet and nutrition app may get a lot of fans.

How to develop it?

Recommendations for developing mobile applications

The development process and architecture of mobile applications are generally similar to web applications. Yet, there are certain aspects to consider. Let’s talk about them a little.


Implementing multitasking (the ability to run multiple applications simultaneously) on mobile devices poses two main challenges. First, due to the limited size of the screen, it is physically difficult to fit multiple applications on it.

Accordingly, only one application can be in the foreground of the mobile device screen at a time. Second, multiple concurrent and task-oriented applications consume battery power very quickly.

On each platform, the implementation of multitasking has its characteristics, which we will consider in general terms.

Form factor

Mobile devices are usually divided into two main categories with possible intersections between them. These categories are phones and tablets. The diet and nutrition app development processes are very similar for different form factors. However, the design of applications can vary considerably.

The phone screen is extremely limited. Tablets can boast of a larger screen but still, they are also mobile devices. Therefore, the control elements for the user interface on a mobile device are developed according to the form factor limitations.

Fragmentation of devices and operating systems

Throughout the software development life cycle, it is important to consider the differences between devices:

  • Remember that hardware and device functionalities may differ, so linking to certain features may affect your application’s performance on some devices. For example, not all devices are equipped with a camera, so if you are developing a video messaging app, some devices will be able to play video but not shoot it.
  • When designing the interaction mechanism with the application, pay attention to the differences in the proportions and sizes of the screen between the devices. In addition, when designing the user interface, consider the possibility of working with different screen resolutions.
  • Before using any function from the code, you must first test it. For example, before using the camera, you should always ask the OS for information about its presence on the device. When initializing a feature or device, first request information from the OS about current support and use the device-specific configuration settings.
  • Lastly, it is important to start testing the application as early as possible on real devices and carry it out as often as possible. Even devices with similar hardware characteristics can react in varied ways.

Limited resources

The productivity of mobile devices is constantly increasing. Nevertheless, they still have very limited resources compared to desktop computers and laptops.

For instance, desktop developers usually don’t worry about memory because they’re used to having large amounts of physical and virtual memory available. However, on a mobile device, you can quickly run out of free resources by simply downloading a few high-quality images.

In addition, applications that actively use mobile processor resources, such as games or text recognition, can significantly reduce device performance.

Because of this, it’s important to be smart about your coding and deploy to real devices as early and often as possible. This will help you to evaluate the effectiveness of your application.

The peculiarities of iOS app development


With iOS, you can effectively manage multitasking and define several rules and requirements that your diet and nutrition app development should meet. If these requirements are not met, your application may simply be closed by iOS.

Device-dependent resources

Even devices related to the same form factor can use completely different equipment. For example, some devices have only a main camera, others also have a front-facing camera, and some lack a camera. Because of these differences, it is important to always check for a feature on the device before trying to use it.

Operating System Restrictions

To guarantee the health and security of applications, iOS applies many mandatory rules and requirements. Beyond multitasking rules, many event methods have been defined from which the application must return within the specified time. Otherwise, the iOS system will terminate its operation.

The peculiarities of Android app development


In Android, multitasking is implemented based on two components. The first one relates to the life cycle of action. Each screen in the Android app is represented by an action.

And it is defined by the set of events that occur when you bring the application to the foreground or when it goes into the background. The requirements of this life cycle must be adhered to when creating effective applications.

The second component of multitasking in Android is related to the use of services. Services are long-running processes that exist independently of the application. They are used to execute processes while the application is in the background.

Multiple devices and form factors

Google does not impose any restrictions on the devices on which you can run the Android operating system. This open approach has led to the emergence of a variety of devices with myriads of hardware, screen resolutions, features, and capabilities.

Because of the highly fragmented segment of Android devices, most developers choose to design and test 5 or 6 popular devices, focusing on them.

Security and safety

In Android, applications run under a stand-alone identity with limited permissions. By default, minimum permissions are assigned to applications. For example, without permission, an application cannot send a text message, determine the status of the phone, or even go online. To access these features, your application must contain the required permissions.

Wrapping it up

Today, people try to do their best in taking care of their health. That’s why diet and nutrition apps are getting more and more popular. So, if you search for a team of creative and tech-savvy professionals to develop, choose Weelorum.
