App Development in Denver



App Development

Mobile apps have positioned themselves as one of the most effective tools for businesses in the last decade, especially in the field of e-commerce. And it's not for less, because the frameworks promote user existence, encourage interconnectivity and enhance the experience of product and service acquisitions. In short, the use of smartphones has forever altered market dynamics. The implementation of these systems in business models is thus a fundamental pillar for any startup's development. Here in Denver, Zazz has delivered creative and superior programs, and is considered one of the best companies in the United States.

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

Our iOS developers can draw upon years of iOS development experience. We love the challenge, and are enthusiastically designing native iOS apps. Our iOS developers look forward to every single project, big or small, basic or complex! Native iOS development shouldn't turn into a black box. And we work with quality-consciousness and log our applications for iOS.

Mobile Backend Engineering

Developers, whose main task is to implement outstanding app frontends and a smooth user experience, invest most of their time in implementing backend integration. The problem is exacerbated by the fact that different platforms such as iOS, Android and possibly even Windows should often run the same solution. Several times the same integration problems are resolved, in part by different developers. There is a risk that it will suffer from issues such as safety, quality and functional aspects. Fortunately Zazz has invested in Mobile Backend Engineering and got what it takes to perfectly program an app.

QA and Testing

The variety of mobile device hardware and software is called fragmentation-this poses many challenges to quality assurance of apps. It is where mobile device testing comes into play: it tests whether an application will run under various conditions and if it is difficult to replicate the applications. The detection and correction of these violations will guarantee as many users as possible the desired user experience. Because the application has the widest possible range only if an app offers good performance and user-friendliness on as many mobile devices as possible.

Development Approaches

A native app can be loaded to the store and disabled on the tablet or smartphone. Complex projects with a complex user interface that require unlimited hardware access are particularly useful for the creation of native apps.

A hybrid app cannot be described as a pure native application, nor as a pure web application. It's a fusion of the benefits of both worlds-like a marble cake, somehow. Hybrid apps are written with native code, and at any point, HTML5 elements are added. It provides a perfect combination of elements which are native and web oriented.

Mobile App Development

The application offers something extra and not only technically

The technical advantages of mobile applications over the mobile site are obvious, for example in the form of local or push notifications, which keeps users in touch with the application and, in a transfer, with your business. They also benefit from the way users use the app. The user can turn on the mobile app several times a day for a few seconds or minutes while waiting for a bus, and during this time he will do the “most important” thing he can do from his mobile. Such a user does not need all the features you have on the web, because they are just as easy to do on a computer. Therefore, a mobile app should not be a parent site clone in a mobile coat. It should provide a limited set of features, or redesigned the most common interface to best match your mobile app experience.

Applications are used frequently, but in short sections

Perhaps the best example of such an application directly from our workshop is MINDSET. The whole service is very extensive and offers a wide range of features. However, we've selected only the most frequented applications, and we've optimized all the features for mobile so they can be executed as quickly as possible. And that sometimes I need some advanced function or settings? Never mind, that's why the web serves!

Applications can also support your business indirectly

Some businesses tell us that mobile apps are not good for their business. This may be true, but it's good to realize that a mobile app may not serve as a direct "support" for your existing service. A good example is the trade in building materials. Probably no one forensic can expect a person in the field to buy building materials through a mobile application. However, everything can change when a company wants to retain existing customers or attract new ones and comes to the market with a “material calculator” that can quickly calculate the approximate price and amount of material for a particular construction job. Such a well-made app can be used by people who are not yet your customers, but when they recalculate that the color they need is accidentally in action and your affiliate is only 5 minutes away by car, they can easily become your customers.

Set your priorities

At Zazz, we thought the market was big. There are plenty of customers and suppliers, and someone will always be cheaper. We care about quality, interesting projects and long-term and fair relationship with the client. Therefore, we leave clients that are overly price-oriented to others. Now we are dealing with only a few inquiries and after the initial meeting with the client we discover whether it is worth further cooperation. If both sides sit down and the project is interesting, we use our best efforts to do the best presales work and amaze the customer.

This is a huge advantage. We are not dealing with dozens of projects in the presales phase at the same time, but only one or two projects that we are really interested in. We also win often. When we ask our clients why they chose us in the end, we hear that we were the best and that they could see that we really wanted to do it.

Don't be afraid to shatter features!

Finally, I would like to summarize some facts. A mobile site is not the same as a mobile app, and one should definitely not replace the other. The mobile app should contain content that the user wants to use from the mobile, and the app should serve it as comfortable as possible. Fragmentation of features is not a harm, it is always better if the user uses your services on more than one platform. If the app is used well, it will return to it.

You may need an application even if you think you don't need it or it is unnecessary for you, you just don't know which one. At this point, it is best to contact experts who are experienced and able to advise you.
