Development speed

Custom Projects

100% tailored to your specific requests. We do not use ready-made templates or user interface kits that do not suit your specific needs.



We invest heavily upfront in defining features based on your desires, vision, and requirements for your application. Before proceeding with development, we create a detailed document with technical requirements and descriptions. According to your budget and needs, at this stage we provide you with a suitable proposal, which allows our team to know exactly what success is, and you to have an idea of the final result.

Fully functional app


This review period is for you to confidently run your application. During this period, you can test every aspect of your app and note any issues we need to fix before launch. During the review, we run a test version of the application on Testflight, and when you are ready to launch, we will deploy your application and transfer full ownership of the intellectual property so that everything is under your control.
