ASO Optimization & Store Publishing (App Store + Google Play) for a Language-Learning App

Hi, We're about to launch a freemium language-learning app (iOS + Android). We want the store listing properly optimized and published from day one, on both platforms. What we need: - Keyword research and metadata optimization (title, subtitle, description) for both the App Store and Google Play, tailored specifically to the Education / Language Learning category. - We'll provide access to App Store Connect and Google Play Console so you can configure and optimize the listing directly yourself (that's exactly what you're the expert for). - We already have a defined visual identity (a dark theme and an illustrated mascot, used consistently across the app and website) and we'd also like you to design the screenshots and other visual assets for the listing with conversion in mind, built on top of that identity. We'll share our brand kit (colors, typography...) as a starting point. Languages: the app teaches and offers content in 12 languages: Spanish, English, Portuguese, French, German, Italian, Russian, Japanese, Korean, Chinese (Simplified), Arabic, and Hindi. The interface is available in the same set of languages. We're especially interested in optimizing for Europe, the US, and LATAM, though other markets tied to those languages are of interest too. Current status and timeline: the app is currently entering external testing. We're aiming to launch around September-October, with November as our hard deadline. So there's room to do this properly, but we need it wrapped up well ahead of that deadline. Best regards
