Mobile App Development

App Development in Chicago



App Development

An application is designed entirely and only for a specific platform (Android, iPhone, Windows Phone, etc.), unlike a mobile site, which is generally only an adaptation of the original site. Because of this important difference, applications often have more suitable interfaces, better ergonomics and faster than a mobile site. The possibilities in terms of development and ergonomics are therefore more advanced for an application. In addition, and this is a significant point, the application is accessible (once downloaded) even without an internet connection, which is obviously impossible for a site. Zazz has mastered the art of developing mobile apps and is creating wonders here in Chicago.

App Development


iOS App Development

It is one of our premium software tools including Swift coding, simple UI design principles, iOS content integration and prototyping. There is no question that Apple offers uniqueness, and we are also making sure that our products based on iOS offer the same.

Android App Development

Android is an operating system utilized by most manufacturers. From the wealthy to a common man, all have access to the internet thanks to budget phones. We're making sure our Android apps are available, making them fully usable.

Mobile Backend Engineering

The back-end developer works on the server-side, behind the scenes, allowing the user to enjoy his work experience. We apply ASP.NET, PHP, Ruby, Python, and Java and so on effortlessly and keep in mind the main consumer idea.

QA and testing

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

Native App Development

We know that all kinds of system functionality, sensors, and 100 per cent quality are achieved by going to the native app.

Hybrid App Development

Hybrid apps are increasingly being used in the mobile world today, because of their cost-effectiveness and streamlined interface. We have designers at Zazz who are able to create hybrid applications based on incorporating all the focal points of the customers.

iOS App Development

Following the development of your iPhone application, we can support you when it is published on the App Store and develop a personalized communication strategy, according to your needs, to promote your mobile application. In the same vein, we are implementing tracking and analysis tools to measure the performance and campaigns of your mobile application. On the other hand, to adapt to regular updates of the iOS operating system and the release of new iPhone models, the Zazz mobile agency can take care of the maintenance of your mobile application. Thus, you ensure its continuity and optimal operation.

Mobile Backend Engineering

Note that as part of a business application project (BtoE), a good mobile backend capable of embedding the profession (software and databases) independently will allow you to obtain a test version more quickly, leaving the dynamic connection with the information system at the production phase.

QA and Testing

Any development must be accompanied by an advanced Testing phase called “recipe” to ensure the reliability of the deliverables. In fact, your users will not stay that long if your app does not reach an acceptable level of quality (instability, crash, functional bug, latency, etc.). We often hear that tests are time consuming and are considered a bonus. However, the earlier they are integrated into the development of the project the more they will be relevant and effective (and will cost you less!). To guarantee the quality of your app, therefore entrust the testing phase to experts. Project managers are often asked, although it is not their primary task, they are however better placed than developers who regularly test and debug your app, but will not have an objective look and the ability to get started. We also perform tests on a variety of devices (screen size, resolution, OS version, etc.), because what applies to one does not guarantee for all…

Development Approaches

It is an application that is developed in the language of the operating system. The language is not the same depending on the system. A native application performs better than a hybrid application or a web app..

A hybrid application allows faster development, the language used is compatible with several operating systems.

Mobile App Development

A really suitable format

I do not know if you have noticed, but like what is practiced on the "office" web, mobile applications of media sites are also more and more frequently responding to common standards of interface and ergonomics (sequential navigation buttons, adjustment of the font size, sharing in social networks and by email, etc.). Even if that is not a sufficient argument (we can very well do the same thing with a webapp), these standards contribute to a standardization of interfaces favorable to users. On the other hand, a well-designed application is really adapted to the mobile experience because it is a real software produced using development tools specific to the platform and not the sometimes awkward adaptation.

Greater ease of use for the general public

With the development of App Stores (and of course more precisely that of Apple) we are witnessing a reversal of practices that we would not have imagined in the heroic times of the pioneers of the mobile: it is easier today to install an app than go get the mobile version of a website. Based on the observation that the iPhone is now a very mainstream mobile, when I look around among "normal" people (understand: non-geek and not necessarily up to date with the latest technology), I am surprised to see the number of apps they have installed on their iPhone, and to find that most of these apps are those of media websites. So many regular and loyal users of the 20 Minutes applications, which represents hundreds of thousands of page views more each day for these publishers. And yet most of these sites also offer a mobile web version! Does the general public use the mobile versions of these sites? The answer is no, for sure. Why? See next point.

The general public hates URLs

No need for marketing or behavioral studies to make this observation: people hate URLs! The storage capacity of a domain name in the average homo internet must be limited to two or three, no more. Take the test around you and ask someone to give you the exact url of the three or four sites they frequent most. Also look at the way that the same people find their favorite sites: by entering their name in Google, which has become the first address bar in the browser. In this context, imagine in addition that it is necessary to memorize a mobile address, among this small non-exhaustive anthology of addresses as friendly: just impossible. While with an application, all the work is chewed: you install and to you the mobile web, clear and simple as an icon. People love the concrete, which is packaged and ready to eat. An app (and its icon) perfectly meets this expectation. Which brings us to the next point.

The general public loves icons

The iPhone did not invent the mobile icon interface, but it did impose it as the only valid standard. No wonder then that the public is in favor of this type of navigation where applications hold a special place. Once again, simplicity of use takes precedence: it is much easier to read Le Monde on your iPhone or Android by simply clicking on an icon than if it requires launching your browser and then looking for the site in the list of your favorites. (When you only know that the favorites function exists). It may just be one click less, but it is that one click that makes all the difference. You tell me that you can create a favorite icon on your iPhone screen with any website: it's true, but how many do it? And how many can make a personalized icon?

The push

Some media applications offer a push function that displays the latest news (or a selection of these) in a small alert window on the screen of their iPhone. This is the case, for example, of Le Monde (again!) Or This is an interesting function which can prove, depending on the case and the individual, very addictive or, on the contrary, completely unbearable. But whatever one thinks of it and whatever the use that one makes of it, this one is to my knowledge possible only by the intermediary of an application. Functionality all the more appreciable in the context of a single-task device like the iPhone.
