Our idea of a smartphone app that runs on iOS and Android will be materialized professionally using React Native and Flutter which is a leading industry-standard technology developed by Facebook and google. We are a team of professionals, having great experiences developing react native and flutter mobile applications. Everyone in our team is having minimum 5 years of React native and Flutter development experience, we also developed back-end and web application so feel free to contact us for a complete application. Please note that an Apple Developers Account is required and I will need to be added to it for an iOS build of the app. If you have any more questions then please send a message my way and I'll reply as soon as possible.
