App Project Conceptualization and Planning

You are purchasing 1 project specifications document for your app project. You can choose to have us create 5 original app concepts for you. We will work with you collaboratively to arrive at a final app concept that aligns with your vision and is ready for the design and development stages of production.




With this purchase, you’re paying for Phase 1 of our app development process. We break app development into phases.

  • Phase 1: project conceptualization and planning (this phase).
  • Phase 2: user interface (menus, pop-ups, etc), illustrations (mockups, character art, etc), sound and music. Typically completed in 4 weeks for $1,500.
  • Phase 3: app development, usually produced with Unity. Results in a finished app published to the iOS and Android app stores. Typically completed in 12 weeks for $6,000.
  • Phase 4: user testing and final revisions. Typically completed in 4 weeks. Final payment due upon approval, typically for $3,000.

During Phase 1, we will produce a project specifications document. The document defines the mechanics of how your app works, the screens your app includes, and the graphic and audio assets required to make the app. This document serves as a roadmap, which you can use to begin app development whether you work with Nexus or another development company.

If you want to produce an app or game, but you’re not sure what idea to pursue, you can select “Specification Document + 5 Original Concepts.” With this option, we’ll provide you with 5 separate original ideas complete with description, references, and visuals. We’ll get your feedback and keep iterating on these ideas for up to 3 iterations until we arrive at a concept that you’re excited about producing.
