In the initial meetings, we discuss the viability of your idea and the high-level goals. Then we come back to you with a proposed project plan. Any negotiations of the budgets and timelines may take place. Once both our parties are agreed, contracts are signed and a dedicated expert team is assembled to start the project!

Our skilled UI/UX designers come up with the initial drafts of the look and feel of your app. Few iterations of these wireframes may happen to get it just right. On the engineering side, our developers work on the overall architecture and the design of the app solution.

Moment of truth! We prepare the App Store/Play Store pages and push the final version to it. You may choose whether you want to do a gradual, soft launch or if you want to make a big splash, a big bang launch!
After the warranty period, you may choose to continue to work with us to build new features, optimize and upgrade the codebase as time goes on.
