Mobile Backend Engineering

Thanks to the use of a mobile backend, marketers can now respond precisely to their customers' requests: cms, ad server, positioning on stores, and distribution of uses on different devices (smartphone, tablet etc.), geographic distribution, usage habits, data updates and qualification of mobile user profiles.

QA and testing

We also consider our customers ' needs and goals at Zazz. Upon releasing the app, we not only do QA sessions but also build mid-sessions with clients from scratch to prototype. As prevention is better than cure, we check the app many times.

Native App Development

They are the market favorites because they offer more powerful results in terms of design, usability and efficiency. Its distribution is done through the official market place of each operating system, which guarantees full visibility and security.

Hybrid App Development

Hybrid applications are mobile applications designed in a web programming language either HTML5, CSS or JavaScript, together with a framework that allows you to adapt the web view to any view of a mobile device.

iOS App Development

Apple's native mobile application development language, Objective-C, was one of the first programming languages and proved useful for creating applications on multiple devices. A more modern programming language is Swift, which was launched in 2014 and was created as a replacement for Objective-C. Thanks to its simplified language and advanced error control system, it is easier and faster for developers to create applications.

Android App Development

Android applications are programmed in Java, currently the most popular programming language in the world. While Java requires a lot of coding, there is an alternative: Kotlin. This coding language is easier for developers to read and coding can be done more efficiently. Another popular programming language for Android applications, especially among junior application developers, is C #. It is compatible with useful tools like Unity and Xamarin to create multiplatform games and applications.

Mobile Backend Engineering

The mobile backend allows developers to easily design application projects and offer an optimal administration platform, thanks to many features: flow synchronization, campaign management, push notifications and ROI analysis and statistics use. With a mobile backend, developers are now gaining productivity thanks to the development of cross-platform applications much faster. On average, this is around 50% of time saved compared to ad hoc development (development without infrastructure).

QA and Testing

Usability testing verifies how user-friendly the app is. In this case, a self-test is not an option, since only users can determine how easy or not to use an application. Also the use of an emulator or a simulator is not very useful for the aspects verified by a usability test because only on a mobile device it is possible to evaluate the functioning of an application. Only in this way it becomes clear how the touch screen works, how you can scroll a page or how you press the keys and what the app's reaction times are to these commands.

Mobile apps demand a specific type of strategy and agile development. We strategize the whole process for our clients and offer them a roadmap.

Mobile App Development

If a company without a website was considered outdated and unable to compete a few years ago, today the one that does not have a presence on mobile devices will suffer the same fate. And in that framework, no tool as promising and appropriate, as apps or portable applications.

In a world in which consumers saturate the network with searches, downloads and all kinds of pages viewed from their mobile phones, the optimization of the websites of the brands and the creation of applications for this type of devices is elementary. Not in vain recent studies reveal the large amount of time that the public devotes to apps. According to these, smartphone users spend up to 127 minutes a day, whether to play, classify your agenda, perform banking operations, search various topics, enter social networks, download music, read documents, etc., and so on.

Such frequency of use makes smartphones a very attractive field for trade that in fact, since the spectacular appearance of the iPhone in 2007, is constantly exploited. Just take a look at the size of the traffic on the web and check that approximately 10% to 25% of the traffic they receive comes from mobile devices, to understand why the percentages only grow over time. This and other indicators (such as selling more tablets and smartphones than PCs today) make visible the need to have a presence in the mobile world that, as we know, is very competitive and full of products. How to achieve it?

What to consider before having a mobile app?

Before finally deciding to bet on ordering the design of an app from professionals (there are programs to do it by hand but we do not recommend it in any way) you should reflect on certain things. We say this because some companies mistakenly assume that having an application means being "fashionable" or as a task to meet new trends, without calibrating the actual results they could obtain and without knowing their chances. Worse, based on the real ratio between application inquiries and final project contracting, it is perceived that there are companies that come without having the slightest idea of what they want. Many concerns are forgotten because the client does not really know if the application will be profitable or even if he really needs it.

Business apps

To overcome this we must consider whether the objectives of the company need to create and manage an application, and then deepen their variables. It has a reason. Applications usually work best when customers already know the brand or have an affinity for it, so if the goal is to improve the brand experience or build customer loyalty, an app (an optimized website) is a good way. On the other hand, if the objective is to give visibility to the brand through an application (a native app), we must not forget that it must first be made known, which naturally is a long-term strategy. It is true that the life of an app can be a couple of months, but do not forget that once downloaded you can stay there forever. And above all, regardless of how long you stay on the mobile, whenever it is used, it must be efficient and provide quality services indefinitely.


Another important aspect are the objectives. When creating a mobile application it is essential for the company to establish a clear strategy, in which the design is key as a subsequent weapon of engagement with users. Be clear about all the points before thinking about what you want: a mobile application that will be plowed. If there is a way to ensure success on mobile devices, it goes through a category that is popular and create a product capable of creating a native mobile experience. As in any area of marketing, being unique is an attribute reserved for a few. Try to be one of them.

iOS or Android?

And finally, now that your expectations are more grounded and have grown, it's time to take a look at the options. Which one to choose: iOS or Android? (Development for BlackBerry at this time is no longer a priority for most companies.) About iOS we can tell you that it is the standard and offers the opportunity to create an elegant application. It has several positive points such as good design, ease of use and a variety of applications and huge games that make it a benchmark. Its perfect integration with cloud services and desktops, especially Mac, is another of its strengths. On the other hand, Android has a greater potential audience - the largest operating system in the market worldwide. It is practically adaptable to all types of devices, is modifiable and upgradeable, accepts any application (something very important), uses any operator, is customizable and has multitasking capability.
