I need an iOS and Android application, fully packaged for App Store and Google Play submission, that turns a user’s uploaded photo combined with detailed text prompts (from the app) into a polished cinematic video. The core engine is Veo3 accessed through the Gemini API and using Flow, so the build must cover secure API authentication, prompt handling and streaming the resulting footage and editing back to the device. Video styles The app should let users to pick among Action, Romantic & Documentary and Sports scenes with the flexibility to add many more genres. Internally, the prompts you pass to Gemini (for each type of scene) will be predetermined and stored in the app but the image uploaded will be individual to each user.. Key functions • User account creation with email and social media (plus Apple/Google sign-in) • Photo upload and crop/preview before submission • Rich text-prompt entry with character counter • Real-time status updates while Veo3 renders the clip • In-app purchases / subscriptions handled via Apple’s StoreKit and Google Play Billing • Local gallery to rewatch, rename or delete generated videos • Automatic clean-up of temporary files to keep the install size lean Social sharing of generated videos Scheduling with prompts for the user to watch the video/s ability to select characteristics (multiple-choice) of another key character in the VEO3 generated video Compliance & release All store assets—screenshots, privacy policy URLs, icons—must be included alongside signed IPA and AAB builds ready for direct submission. Source code (Swift/SwiftUI for iOS, Kotlin for Android, or a cross-platform framework if you prefer) and a concise README are part of the hand-off. Acceptance criteria 1. A test build on TestFlight and Google Play Console alpha track that passes review. 2. Successful generation of at least one video in each style using a sandbox Veo3 key. 3. Payment flow completes and unlocks the generator without errors. 4. Code compiles from a clean checkout with documented environment variables. That’s the full scope—once those boxes are ticked, we’re done. The brief for the app front end will be provided via a Lovable working web app so very detailed and efficient. The build you complete however, has to be native from the ground up to ensure a quality app is produced and approved by the iTunes Store in particular. This means including a number of native features including offline functionality, fallback, access to device hardware like the camera & microphone, Siri, push notifications and integration with the iOS ecosystem.
