Mobile App Development

App Development in Washington



App Development

Tens of thousands of companies offer their services first and foremost via a mobile app and many businesses are completely dependent on one or more apps. Spotify, Facebook, and Netflix are three examples of companies that mainly exist in people's lives as icons on the mobile screen. But a mobile app doesn't have to be big and do everything. An app can give businesses more natural and easier ways to interact with their customers or allow users to do brand new things. An app can be a game, a digital map of a building, an interactive guidebook, and a thousand other things. Apps are tools, and their strength often lies in accomplishing one or a few tasks very well.

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

Design of applications for iOS devices is important if we recognize that the use of this operating system has greatly increased in recent years. For this reason it can be very useful for your company to adapt to Apple's own framework. There are times where this may be an area of considerable significance depending on the type of audience we're discussing. All this without forgetting the value for our organization of creating a mobile application. The level of proximity that it provides to us about our target audience puts us in an advantage situation.

Android App Development

Flutter is Google's open source framework for reactive programming. It's still new, but has grown rapidly since its inception in 2018. Flutter completely bypasses the platform's components and renders UI and graphics in its own 2D rendering engine. In this way, you can create very fast apps, which are not as dependent on built-in components. Developing an Android app would allow you to always go into and be closer to the pocket of your target audience, increasing the chances of this engagement with your brand. The first step for this is to design the purpose of the functionalities this application must have. The Zazz team will be happy to hear your idea and come forward with a strategy and design to suit your needs.

Mobile Backend Engineering

For mobile and web applications, we often talk about front- and back-end. While the front-end defines the user interface, interaction with the user and presentation of information, the back-end deals with business logic, data storage and security. From the perspective of a mobile developer, the backend seems to be another world, populated with databases and servers. So not only are developers expected to create beautiful high-performance mobile interfaces, but they must also be well informed about network infrastructure such as web servers, database management software, server-side scripting languages and much more.

QA and Testing

Today, consumers can interact with their favorite brands on an unlimited number of connected devices: phones, voice-activated speakers, on-board entertainment, the list goes on. Add specificities to each country and any company that wishes to offer a coherent experience faces a formidable challenge.

Thanks to the largest community of testers in the world, Zazz provides you with instant access to a large list of devices and operating systems, whether historic or just released. And as the tests are performed on real devices belonging to real people, this list continues to grow as the market evolves.

Our Android App
Development Approaches

Applications developed on the native programming language (Java, Swift, Objetive-C…) of the device. These applications are 100% platform dependent. Therefore, we must develop and maintain a complete application for each target platform (iOS, Android or others).

Applications developed in HTML, CSS and Javascript that run on an abstraction / framework layer (Apache Cordova, Ionic, React Native, Capacitor ...) that provides access to the terminal resources in a neutral way to the type of device. Therefore, through this paradigm, a single common application is developed and then prepared for each platform (with small functional adjustments if necessary).

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

Now you are still a trendsetter with an app, while prices are already falling.

The use of smartphones is growing fast, almost faster than the amount of apps that are made. The more smartphones, the more apps there are. In a few years, every company will have a pair for several purposes. That means that a company can now distinguish itself with a mobile app. It is true that most apps are still entertainment apps that we can actually do without, but use is growing fastest in the business apps category. These are apps that provide sales teams with promotional material and instructional films, apps with advertising options and apps as location-specific marketing tools.

The use of business apps is not yet very widespread. The prices of mobile apps have fallen considerably since the introduction of cross platforms. So you now get the best of both worlds: you are one of the first with a business app and you benefit from the sharply lower prices in a competitive market.

Everything revolves around marketing: always in contact with the customer

Why does our company need an app? Why do we need a website? Mobile apps are on the user's smartphone. With an app you are always visible on the customer's favorite means of communication. As a company, do you dream of that? A tap or a swipe and there is contact, without the intervention of a restrictive browser, with a superior user experience.

Use an app to inform customers via Facebook, Twitter and Google+, among other things. Sell products from your app and let the payment go through PayPal, send users push notifications with special offers. Collect data from customers and provide feedback and support. You can even integrate your loyalty card in the app. Smartphones are the most used means of communication in the foreseeable future and mobile apps are the best way to facilitate contact with customers.

Operational management gets better with mobile apps

Operational management benefits from the mobile revolution and the increasing use of apps. It all becomes a lot more efficient and easy. Are you organizing an event or conference? Then you quickly create an app that presents visitors with all information in a well-organized way on their smartphone: the program, speakers, profiles of fellow visitors and of course route navigation to the location.

It goes without saying that you don't have to pay a whole year for an app that you use for only a few weeks. Just use the same app for multiple purposes. After all, updating and converting is easy once the app is in the stores.

Are the people from the field still lugging boxes full of brochures? That can be much simpler and nicer in an app on the smartphone or tablet. You can provide apps with beautiful portfolios or clear instructional films. You can give customers or users access to only a part of the app by only releasing certain parts in the app with a password. Moreover, apps are always current and even work without an internet connection.

Easy to maintain

You can partly maintain your own app with a CMS. That works very easily. Anyone who can use a computer a little can make small changes to the app. keeping some information in the app up-to-date is even completely automatic. We link your data with a web service and you no longer have to worry about it. All changes are automatically in the app.

More customers through minimal effort

As a business owner, your goal is to reach as many customers as possible. Often this is still done in the traditional way. Consider: the newspaper, billboards, etc. Time is moving forward and you need to use new techniques to reach more potential customers. A mobile app offers the possibility to communicate directly with your target group.

You can promote products and services in a fast way. In addition, a mobile app helps to find out the opinion of the customer that you help determine your strategy.

Valuable feedback

You are probably aware of the fierce competition in the market. It is very difficult to keep your customers interested for a long time. Having said that you do have the opportunity to use their opinion. If you process customer feedback properly, your product or service can be improved.

Whether you have an Android or iOS app, the ratings and reviews say a lot about the customer's experience with your product or service.

This feedback is a parameter that allows you to better assess your product or service. If you continuously receive negative feedback, it is important to find out why this is experienced in this way. It comes down to taking customer reviews and reviews seriously and taking this into account.
