The way they understand the requirements we present to them is fairly solid. Both in terms of bringing their own interpretation in nailing the requirements and their design sense. By the time we launched, I had gotten significantly more value from our collaboration than what we had discussed in the original specs.

This is a boutique development firm where the Founder is directly involved with the project and the primary contact. This is unlike many development firms where you are simply handed off to developers that are not stakeholders. This is an important distinction that results in much better project accountability.

Idea Maker's portfolio is what drew us in. Their design style was in alignment with what we were after. We had initial consultations with 3 companies that we had narrowed it down to. Once we had our initial meeting with Tom at Idea Maker we knew we had the right choice to make. Their communication style works well for us.

As a mobile app development company in California, for nearly a decade we’ve honed our app development process to ensure quality with every project. We follow an Agile methodology that facilitates a flexible development process, increasing development speed and providing various scalability options.
Location Step 1

Consultation & Planning

We start every project with an initial consultation wherein we take time to fully understand your mobile app idea, your requirements, and your business. Once we’ve gathered enough information, we can then put a plan together for you to review–this will include everything from estimated development hours to the framework we plan to use.
Location Step 2

Design & Prototyping

The next step is to create a design for your mobile app based on your requirements. We build an interactive prototype that highlights intended features before adding athletic design. This allows you to test the app before its development, ensuring every detail is correct.
Location Step 3

Development

When you’re happy with our design and proposed functionality, we get to work actually developing your mobile app. Thanks to our iterative Agile approach, we’re able to test features as they’re built, speeding up development time and preventing bugs from slipping through the cracks.
Location Step 4

Launch & Deployment

Once your mobile app is built, we then work with you to get it on app stores. This involves ensuring the app meets App Store and Google Play Store guidelines and sometimes requires some back and forth. However, we guarantee that we’ll meet the store requirements for your mobile app.
Location Step 5

Maintenance & Updates

After launch, we’ll stick around to help keep your mobile app properly maintained. We offer post-release support packages to ensure that your app continually delivers an exceptional experience to its users.
