The average cost to develop an app is about CHF 10,000. If you want to create customized, complex apps, you may need to pay more than CHF 300,000. The cost of app development for mobile apps depends on various factors, such as:

  • App functionality
  • Development approach: hybrid, native, or cross-platform
  • Platforms: Android, iOS, or both
  • UX/UI design requirements
  • Technologies 
  • Integration with third-party services
  • The mobile app development company you choose to develop your mobile app

Each mobile app development platform has pros and cons. More specifically:

  • Native development (Android and iOS): This platform comes with the best performance and access to platform-specific features. You can also integrate your apps with the respective systems. However, this option demands separate codebases for Android and iOS, which may increase app development costs and time. 
  • Cross-platform development: On this mobile application development platform, you can write your code once and then deploy it on various platforms to reduce development cost and time. Unfortunately, you cannot access platform-specific features. Moreover, your apps cannot be optimized easily. 
  • Progressive web apps (PWAs): You don’t need separate app stores for your PWAs because you can access them through web browsers. These apps are also easy to update and maintain. Yet, compared to native apps, PWAs don’t have as many device features. They don’t offer the same degree of user experience and performance either. 
  • Hybrid mobile app development: In this approach, you use web technologies and access native device features to accelerate the development process. However, your apps may come with fewer platform-specific features. Plus, you cannot optimize them easily as you would with native apps. 

Yes. The mobile app development cost depends on many factors, such as project scope, app functionality, platforms, UX/UI design, technologies, and its features. But don’t worry! As a dedicated and friendly mobile app development company, we offer low-cost services to optimize the app development price.

You can choose one from the following outsourcing models: 

  • Time and material or fixed price contract: In this model, we provide a highly experienced project manager to take care of your project. 
  • Dedicated team contract: Our outsourcing app development team works exclusively on your project, while the team’s management is on your side.

It takes about two to three months to get your MVP ready and deployed. You may wait for three to ten months if you want to have a full-fledged mobile app.

Our NDA and ISO 27001 certifications ensure high-quality mobile app development services with security as a top priority. We also have years of experience in creating healthcare and BFSI apps.

We stick to advanced technologies when delivering app development services. Here are the top trends in mobile app development that we follow:

  • Internet of Things (IoT) app integration

  • Applications for foldable devices
  • Augmented Reality (AR) and Virtual Reality (VR)
