I'd react-native anytime. It is easy to learn for devs, has a lot of resources online, and when it comes to delivery, it supports iOS and Android both. If you're in an early-stage company, react-native also helps you keep the costing low as possible, as compared to running 2 different teams and 2 different tech stacks for your mobile. We help our clients on building and scaling apps., reach out to me on how FirstPrinciples.io can help you develop your world-class app in a cost-effective way. If you're looking out for a cheaper solution, I'd suggest hiring a react-native developer from Upwork. Cheers.,
