FAQ (Frequently Asked Questions)

Mobile app design services are full assistance that development companies, such as ours, provide for the development of your own mobile application, from the strategy and ideation to a full-blown product and its deployment. With the help of our development company, you can get an iOS and Android application that is a quality substitution and an accomplished companion or accessory to your existing web solutions and/or offline products. Your app needs to work closely and in concert with the rest of your business services. As an app design agency, we always consider the entire ecosystem that each app will inhabit. That way, integration, and implementation are always seamless, and your app performs flawlessly, offering a robust platform for your mobile users. Mobile apps are a valuable addition to any business. The most effective are mobile apps for the banking industry, communications, e-commerce, m-commerce, travel, healthcare, entertainment, etc.

Yes, we do! Here at Merge, our team consists of UI designers and developers who are already in sync and know how to work together productively and efficiently throughout the app design process. Our experience and combined expertise let us meticulously and without hassle create a finished product. We strive to always keep our mobile app development on par and equivalent to design services and our web app development services. The main benefit is that you don’t have to hire two different agencies for app design and development and have one review the other’s work to make their own more cohesive and true to your already established idea. Using an app design company and a development agency can also quite notably slow down your app’s release, which is another reason why our services offer a great solution for design needs.

The cost of working with a mobile app design company varies. Sometimes, the costs of design and development can dramatically differ based on a few elements, and every app has different requirements. Here are the most common factors that influence the cost of a mobile application: • Type of application (Native, Web, Hybrid) and its platform (iOS, Android). Mobile apps can also be categorized as basic (simple games, utility tools, clocks, notes), data-reliant (calendars, weather apps, maps), apps with lots of personalization, social, commercial, service apps, etc. • Its size and volume - the bigger and more complex the app will be (for example, enterprise-level projects), the more expensive (obviously) it’s going to turn out. The cost is also determined by the app’s level of customization and post-deployment maintenance. • The number of features and the overall complexity of the app’s functionality. Some apps require substantial data analysis tools within themselves to provide users with relevant information. A more complex user interface design will also lead to increased costs. • The development team’s location and structure. Depending on whether it’s a small firm with mostly freelancers or specialized companies, such as Merge, possessing in-depth experience when it comes to more sophisticated solutions. Location is also vital since the app development costs are shaped based on the cost of living in the developer’s place of residence. Given all that, here at Merge, we always aim for a reasonable price for all our clients and discuss all essential matters beforehand without taking any behind-the-scenes liberties. A very high price does not always equal supreme quality and vice versa. It’s all a matter of experience in mobile app development and design. We keep your best interest in mind with every solution we create and the decisions we make while building an app. Whether that means recommending custom solutions or even simpler approaches that can make the app less expensive to develop.

Not to sound corny again, but it also depends. A lot correlates with our previous answer about the cost of development. More sizable and more intricate apps take more time, while much smaller applications and redesigns can take up to a couple of months. More complex apps contain more design customizations, have more extensive infrastructure, and require more digital maintenance, all of which means more time is needed for mobile application development services to release a worthy product. We discuss any additional time-consuming services with our clients in advance. If you'd like more detailed information about your app, please schedule a discovery call with our development team. We'll do our best to provide specifics regarding your design.

Yes, absolutely! A mobile application redesign is also one of the things our UI designers do well. The redesign involves a thorough review of your app and its metrics, followed by extensive user research intended for our more profound understanding of your users and how to remake the application to better meet their needs. Our team then tests various design choices for the app to ensure intuitiveness and smooth adoption of any change that ensues. We pride ourselves on considering your every business need and requirement while also paying attention to your clients and their feedback when designing an app. Depending on the scope of the app redesign, we may also be able to recommend platform upgrades and other ways to improve your mobile app performance that you can choose to implement.

We have years of experience delivering cross-platform mobile applications for iOS and Android platforms. When we design and build applications, we always strive to give users the native look and feel they expect from their chosen digital platforms. Our app developers can work with your team or independently to find solutions to any challenge you're facing with your mobile strategy. Whether you're having difficulties with a specific platform, security features, or compelling design for your custom mobile application, our design team is always here to help you find what works and what can be improved.

Broadly speaking, our mobile application design and development process follows these steps We collect the requirements of the mobile application or applications you need. Our mobile app UI development team researches your competition and other apps in the same space. When we have a clear idea of the development demands and your goals, we start designing wireframes and, eventually, prototypes of the mobile applications. Then, our mobile app development services include rigorous testing to make sure the app meets or exceeds the desires and specifications. Lastly, we fully support you through the implementation and integration process of your app.

As its name implies, native app development means developing apps that operate natively within the context of a single mobile operating system, such as iOS or Android. In contrast, cross-platform app development uses frameworks that allow the same code to be used on several mobile platforms. In a nutshell, the development time for cross-platform apps can be cut in half or less compared to native apps. And, with many of today's highly efficient frameworks, such as React Native and Flutter, there are few downsides to speak of when using native design for a mobile app.

It may seem that after years of a so-called mobile app boom that caused apps to be developed for almost anything, the need for it would die out. Quite the contrary. The mainstream use of apps for everything from fintech solutions to entertainment has allowed mobile app design to mature and become increasingly refined. We now can observe a more steady digital market, with users finally aware enough of their own app preferences in each industry and developers having a more steady hand in producing well-researched applications. According to the latest Mobile App Market Outlook from Sensor Tower, the number of mobile app downloads has grown more than two times in the last eight years or so. It stands to reason that the investments in your own mobile applications in the current market are more than rational and can definitely prove themselves worthy. A mobile app can enhance your branding, increase lead generation, and improve your user experience.
