If the app is the product, it should feel native. Major apps lie WhatsApp, Snapchat, instagram etc are built natively because that’s what users expect of a professional app. If the app is auxiliary to your main value add, and users primarily use your product on desktop, then a mobile website might make more sense. Have you considered a middle ground of something like react native?
