Tech Stack

React Native + Expo + Firebase
Built with Expo SDK for cross-platform delivery and Firebase for auth, database, and storage — a production-grade combination for modern mobile apps.

Platform Coverage

Android & iOS (Single Codebase)
Both platforms are covered from one shared codebase using Expo, reducing development time and keeping your app consistent across devices.

Delivery Window

7 to 21 Days
Basic prototype delivers in 7 days, while the Premium tier with full backend allows up to 21 days — giving buyers flexibility based on project complexity.

Source Code Included

All Tiers
Full source code is handed over across Basic, Boost, and Premium packages, meaning buyers retain complete ownership and can extend the app independently.

As my tech advisors for both front-end and back-end development of my mobile app has been an incredible experience. Their expertise, attention to detail, and dedication to building a high-quality product have truly stood out. From the very beginning, they provided clear guidance on the best technologies and frameworks to use, helping me make informed decisions that aligned with my goals. Their proactive approach to problem-solving, combined with their ability to translate complex technical concepts into simple terms, made the entire development process smooth and collaborative. Thanks to their support, my app not only looks great but functions seamlessly. I highly recommend them to anyone

El equipo de Creative Feel me está creando una web+app. Ellos ofrecen buena atención, buen manejo y precios competitivos. Es cierto que ha habido un retraso imprevisto, pero se nota que están intentando retomar los tiempos de entrega. De momento estamos contentos con las entregas de backend e iniciando con las de Front y para crear una opinión más sólida de sus servicios, sigo a la espera de sus siguientes entregas.

Muy buenos profesionales!
