English Question Curriculum & App Logo -- 2

I’m building a language-learning app aimed at teenagers and I want its first release to feel as engaging and game-like as Duolingo. To get there, I need two things developed in parallel:

• A complete English-learning curriculum broken down into XP-style skill trees, each packed with varied question types (multiple-choice, tap-match, type-what-you-hear, fill-in-the-blank, etc.). Every unit should clearly state its grammar or vocabulary target and come with enough graded questions to support spaced repetition. Deliver the content in a clean spreadsheet so I can import it directly into my CMS, along with a concise guide explaining the logic behind the difficulty curve and any media assets (audio snippets, sample sentences) you create.

• A fresh, memorable app logo that speaks to a teenage audience. I’m after a flat, modern look that still feels friendly—think bold colors and rounded shapes rather than corporate minimalism. Please provide the final design as an SVG plus PNG exports in the common sizes for iOS, Android, and web.

I’ll review the curriculum for pedagogical flow and accuracy and test the logo for clarity at small sizes before signing off, so editable files (Illustrator, Figma, or Affinity) are essential. If you have previous work on gamified language platforms, let me know—seeing live examples will help speed up approval.
