Arabic Audio Library App Development

I have roughly 150 guided-audio recordings in Arabic, each about ten minutes long, that I want to package into a dedicated mobile library aimed at easing stress and anxiety. The app must launch on both iOS and Android from a single codebase—Flutter or React Native is fine as long as performance and future maintenance stay smooth.

Core requirements
• Native-feeling Arabic experience: full RTL layout, proper typography, and diacritics handling.
• Account system that supports email signup, social-media log-in, and an integrated payment gateway so listeners can subscribe seamlessly.
• Audio files stored on Google Cloud Storage, streamed with buffering that feels instantaneous even on slower connections.
• Modern, sleek interface: dark and light themes, unobtrusive navigation, and a listening screen that lets users scrub, loop, and pick next tracks without friction.
• Admin console or simple script that allows me to upload, tag, and reorder the 150 files without cracking open the code each time.

Deliverables
1. Source code with clear build instructions.
2. Deployed test builds on TestFlight and Google Play Console.
3. Brief hand-off document covering GCS bucket setup, subscription flow, and how to add new audio.
4. Two weeks of post-launch bug fixing to iron out any edge cases.

Acceptance criteria: a new user can install the app, register via email or social, purchase a subscription, browse the full library, stream any track with no noticeable delay, and switch the UI to RTL without glitches. If this sounds like a challenge you enjoy, I’m ready to get started right away.
