Frequently Asked Questions (FAQ's) About App3null Projects

How long does it take to develop an app with App3null?

While a basic version of a mobile app can take up to three months to develop, complex mobile app development can proceed for nine months. 

What are the costs of mobile app development?

The cost of an app varies, even among apps that belong to the same category (e.g. dating apps or logistics apps). Costs for basic apps are usually around 5,000 euros. There is no upper limit, depending on the duration and complexity, a mobile or web app can cost 100,000 euros and more.

Read App3null average mobile app development cost in 2022. We give you a deeper insight into the factors that exert an influence on app development costs. At the same time, we list sample budgets for different apps.

What are the prerequisites for a mobile app development project?

Anyone who has made it this far will be rewarded with a short summary of what is important for successful app development:

Define clear goals and set KPIs for the project:

  • Design the concept
  • Provide the developers with sufficient input
  • Allocate sufficient budget with enough buffer
  • Select the best partner agency for your idea

If you want to be on the safe side, you should contact us directly and don’t keep looking forever, because we are an agency where software projects don’t fail.

How can I find good investors to fund my app development?

Your app development project can’t kick off without the essential funds. There are many ways to find reliable investors for your app development.

There is a large amount of grants and funding that want to advance the topic of digitalization. We help you with both the application process and the development. Together, we apply for funding for your project and implement it. For more specific information you can visit our page about subsidies for digitalization.

How do we communicate with the project or software development team?

Permanent coordination and communication with the developers is another important factor for the success of your project. If you have your app built by an agency, you should hold regular meetings or calls. At APP3null we have weekly calls with our customers. Regular face-to-face meetings don’t hurt either, provided the circumstances allow it. However, online meetings and calls do not have a major negative impact on the projects and sometimes reduce the time required for travel etc.

Do you develop a mobile app for all platforms?

Yes, we build mobile applications for all major mobile development platforms. You can hire our app developers for creating an app for iOS, Android and hybrid. Whether you want to develop apps for just one or two platforms or want to develop an app that works on all the mobile platforms, we are at your service.

How much does a chatbot cost?

The question “What does a chatbot cost?” cannot be answered in a blanket way. As always, the price depends on how complicated the solution should be. As a summary, we can again list the factors that influence the price of a chatbot:

1. building block system vs. programming required.

2. standard backend (from a third party) or own custom backend.

3. standard integration (Facebook, Telegram, etc.) or custom integration e.g., into own website.

4. predefined question-answer tree or AI-based.

5. number of various integrations: from no API integration to complex integration from various sources (e.g., CRM, ERP, HR software, etc.).

What if I want changes to be made in the app once it is launched or delivered?

As soon as you have accepted the project, the source code and ideally also the corresponding rights must be transferred to you. For successful operation of the developed app, it must be regularly updated and maintained. This also applies to the monitoring and optimization of the server infrastructure. Typically, software companies offer this service. With APP3null, software maintenance and support is an optional part of the offer. All successful software needs further development and occasional updates since there is a need for new functions on the one hand and the source code has to be brought up to date on the other.

Which framework or programming language would you use to develop a mobile application?

The framework or programming language that we use to develop applications depends upon the chosen platform by the client. We are very familiar with Android Software Development Kit (SDK), Kotlin,Java, Dagger , ReactiveX / RxAndroid, OpenGL, 3D Graphics, Location-based Service APIs, Android Security Architecture and other technologies. Our hybrid app developers use the following technologies: We are very familiar with Xamarin, React Native and Flutter, as well as 3D graphics, location-based service APIs, mobile app security architecture and other technologies.
