Our Services

Here at Cobalt Sign, we focus on developing qualitative apps for iOS & Android. We take a meticulous approach to create innovative solutions for businesses.

App Development Services

Our app development process covers everything from the ideation stage to post-launch support and patching. This ensures that your app is perfectly suited for the market and that you do not run into long-term quality issues.

With over 9 years of experience and 2 million downloads for our products, we focus on the quality of our apps and an excellent user experience.

Here is what our development process looks like:

Analysis & Specifications

Step I.

Project development starts with the analysis of an app idea, and our top priority at this stage is to determine its viability and implementation.

Each app is built to meet a business objective, address a target audience, have a unique sales proposition, and compete against other players in the market.

You then have to take into account the target platforms, the development budget and timeframe, and the marketing/advertisement campaigns needed to get the app to market.

At this initial stage, we take all these factors into account and map out the specifications needed to implement them.

Once the features and specifications are laid out, we move on to the development stage.

Development & Testing

Step II.

Here we start by mapping out both the UI and the UX of the app, in order to make sure that it will be visually appealing and engaging to users.

We lay out the information architecture and the workflows, create different wireframes to find the best layout, codify everything into a style guide, and iterate through prototypes until the right look and feel are achieved.

At the same time, we are setting up the back-end, by creating the database and server-side objects that will support the various functionalities of the app.

If you already have an API we can use it in the app, otherwise, we can collaborate with your technical teams to create them. The APIs will allow you to integrate the app with other tools and systems.

Publishing & Support

Step III.

Once the app is finished, we will help you deploy it to the Google Play/Apple App Store. Then, we provide ongoing support and updates to ensure that the app stays competitive.

As user feedback starts to come in, you will often find new ways to address the needs of the market, and improve the success of an app.

I've had the pleasure of working with the Cobalt Sign team on a few projects and I'm looking forward to working with them again. Using a clean and structured project management approach, oriented to getting things done, they were able to deliver high quality work on amazingly short deadlines, while leaving out the stress and chaos that usually arises in these situations. Did I mention they consistently create beautiful and responsive UI's?
