If you are running a boutique, then yes, you should absolutely have an online app. This app allows people to buy clothes online, manage pick-ups in-store, and get support on orders should something go wrong. This gets you more sales outside of opening hours and can make it easier for your business to grow as time goes on. An app, though, should be developed for your own specific business.
Many people need to start using a generic app that is for shops. That can work, but they are free or cheap for a reason. They offer more functionality, customisation, and the promise of security. Hire mobile app developers to build the app from scratch, though, and you will soon feel the benefits of having an app developed specifically for your business.
