We do mobile UX, design and app development for iOS and Android.

In order to create an estimate for your app project, the following information is relevant for us:

• Scope of the desired functions and features
• Technology and platforms (iOS, Android, Flutter, React Native, web etc.)
• Integration with other systems
• Required services (strategy, UX, design, identity, software development, etc.)

Details on design ideas, references, target group of the app, time frame and budget are also helpful. For less mature ideas, we can start with a concept workshop to work on these aspects together. If the idea is already fully developed, it may make sense to define the requirements together before we prepare an offer. You can find out more about this in our services.

The cost of implementing a mobile app in Switzerland starts at around CHF 20,000 and can go up to CHF 500,000 or more. The price range depends on various factors, such as the specific requirements and the chosen platforms (iOS, Android or both).

It is also important to note that after the initial development of an app, further costs may be incurred for maintenance, enhancements and optimizations.

We can provide a rough cost estimate for your app project. Get in touch with us and tell us about your idea.

The implementation time for an app varies depending on the complexity and scope of the project. On average, it takes between 3 and 12 months to bring an app from conception to market launch. This timeframe allows us to carefully go through all the important phases of app development, from conception, design and software engineering to testing. Get in touch so we can give you a detailed estimate.

When it comes to developing and maintaining a customised software application, companies are faced with the question of how best to implement their app idea. The two most common options are hiring an external app development agency or setting up an internal app team. Both approaches have their advantages and disadvantages, which we explain in more detail below.

When it comes to timeframes and speed, external development companies like Milk Interactive have an advantage. Thanks to their specialised experts, they can often deliver results quickly. In contrast, building an internal team requires time to recruit qualified employees and establish an effective team dynamic, resulting in a slower start. The existing shortage of skilled labour in the IT industry further exacerbates this effect.
A decisive factor in this choice of "external agency vs. internal team" is also the cost aspect. External agencies charge for their services, which can lead to higher initial costs. In contrast, building an internal team requires initial investment in training and equipment, but can be more cost-effective in the long term - provided that the team can be utilised effectively. Working with an external agency, on the other hand, can be paused at any time and costs nothing during this period.

Control and flexibility also play a role. Working with an external company can lead to less direct control, depending on the collaboration model, while internal teams offer more control and flexibility to react quickly to changes.
In terms of quality and expertise, external agencies often have an advantage due to their broad experience with different projects. And missing skills can simply be booked in without having to start the recruitment machinery straight away. Internal teams, on the other hand, enable a deeper integration into the corporate culture, which can lead to a better customisation of the developed app to specific corporate goals.
Ultimately, the choice between app development by an agency and building an in-house team depends on the specific needs of the project, the resources available and the long-term goals of the organisation. A balanced consideration of cost, speed, control and quality is critical to the success of the app development project.

In reality, it is often the case that a project is launched with an external company and an internal development team is set up in parallel or after some time. This gives you enough time to find the best employees for the job and allows you to act without time pressure. This has often proven to be the most efficient and fastest option.

We offer to start your project as an external development partner and, when the time is right, to support and advise you in recruiting your own team.

Native Apps

Native apps are our specialty. To develop these apps, we use Swift for iOS and Kotlin for Android, two modern and powerful programming languages that are known for their security and excellent user experience.
We are also experienced in dealing with older projects. Our developers have extensive knowledge of Objective-C and Java, which enables us to maintain and update existing legacy applications.

Crossplatform Apps

In cross-platform development, we use either Flutter, React Native or Kotlin Multiplatform, depending on the project requirements. We recommend developing a cross-platform app in particular if the app does not require any hardware-related features. This means that the app does not rely on specific functions or sensors of the device. By choosing a cross-platform solution, we can ensure a high level of consistency across different operating systems and also save development costs and development time.

Progressive Webapps

Progressive Web Apps (PWAs) are another important area of our development work. When creating PWAs, we prefer to use React and Vue.js, two advanced and flexible JavaScript frameworks.

Backend

In the backend area, we use Kotlin or Node.js depending on the project requirements. The choice of backend language often depends on the choice of frontend language. If we create the frontend with React Native, we prefer Node and Typescript in the backend. Kotlin is our preferred choice for projects that require strong type safety and compatibility with the Java ecosystem. Thanks to its language features and ability to avoid common programming errors, Kotlin is ideal for developing stable and maintainable backend systems.
