I’m working on a mobile app concept focused on emotional connection and human interaction, and I’m looking for an experienced mobile professional to review the concept and the existing visual material. Concept overview The app allows users to: Discover anonymous messages placed on a map Unlock these messages by answering a short challenge or question Reveal a personal or emotional message once unlocked Start a private conversation after unlocking The app explores themes such as: emotional intelligence relationships and human connection anonymity, curiosity, and discovery Current state The app is not publicly released I have created: several screens and flows using FlutterFlow a structured user journey (onboarding, message creation, unlocking, conversations) a clear functional logic behind the app (rules, conditions, interactions) I can provide screenshots, flows, and explanations of how everything works At this stage, I am not looking for development or implementation. What I need I’m looking for a senior profile to: Review the concept and user flows Assess the technical and architectural implications of such an app Give feedback on: overall structure scalability considerations complexity of the logic coherence of the product vision This is a concept-level and architecture-oriented mission, based on visuals, explanations, and product logic — not on an existing production app. Ideal profile Strong experience with Flutter / mobile apps Familiar with Firebase-based architectures Able to reason at product + technical level Comfortable discussing apps that are early-stage but well thought-out Deliverable Written feedback (short report or structured message) High-level assessment of the concept and its technical implications Optional suggestions or risks to consider This is a short, focused mission, but it may lead to further collaboration later
