Does every business require a mobile application?

Hello! I agree with Olivia, it's not mandatory, but a lot of businesses choose applications. A lot of people use smartphones much more than it was before, a laptop is comfortable to use only for work. The best example here, as I think is food delivery apps. It's more suitable for me to use a food delivery mobile application, (check https://madappgang.com/blog/food-delivery-app-development-everything-you-need/) than to use a PC, so food delivery application development is one of the best trends in 2021. By the way, apps like Bolt, Uber earned a lot of money just because they decided to invest in mobile apps.
