App development

At Spring Production, we are native app developers for iOS and Android. From ideation to finished app, we ensure the highest levels of functionality and quality. 

We can help you develop any kind of app – even branded games. Just tell us your idea, and we will help you determine which kind of app would be the best fit for your project. Most of the time, the sensible thing will be to develop your app for all devices and platforms. Occasionally, however, it makes more sense to limit the app to iPhone and Android smartphones or iPads and tablets.

1. First meeting

In our first meeting, we begin by discussing ideas and objectives. Next, we can start building a process and a solution that matches your needs.

2. Workshop

The workshop is a great format for defining what your app should do – how should it work and who is going to use it and how. During the workshop, we get input from as many stakeholders as possible to ensure the app concept it bulletproof.  

3. Concept document

Next, we make our first technical and visual draft of the app solution – this is what we call the concept document. In this document, we define whether the app should be a native app, a progressive web app, or a hybrid app.

Native apps are the ones you are used to downloading from the App Store or Google Play. A progressive web app (PWA) runs in your web browser and loads its content from the Internet. Finally, the hybrid app is a mixture of the two and sometimes called a cross-platform app.

Settling this question early in the process is extremely important because time scales and development costs of native apps, PWAs, and hybrid apps can vary significantly.

4. Design

At this stage, based on the design sketches we made together during the workshop, we get to work on how your app works and looks. As we all know from personal experience, design and functionality are absolutely crucial to an app’s success.

5. Requirements

Before we can start programming the app, we agree on the scope and nature of the app, and then write down a complete and detailed software requirements specification (SRS), describing all known requirements, functionalities and the final feature set.

6. Programming and test

This is where it gets real. We start programming the app based on the SRS and will regularly provide you with test versions so you can give us feedback before the final stage. You are involved throughout and will have the opportunity to follow the development process closely.

7. Launch

If your app is a native or hybrid app, the last step involves us uploading it to Apple’s App Store and Google Play, so your target groups can get their hands (and thumbs) on it. If the app is a PWA, we launch it on the chosen website/URL.
