You don’t have to know anything about code to create an app!
There are two types of apps that we deal with. The first would be a native app created for iPhones and Samsung etc. These apps are usually found in their respective app stores. These are far more complex to create and to distribute because the app stores are fussy and complicated. They are definitely not for the faint of heart. To get yours listed at the Apple App Store, you’ll need to build it on a Mac but Android apps can be built on just about any computer.
The next kind of app is a web app. These are essentially super responsive and interactive websites that load perfectly in a phone, a tablet, computer, etc. There are two main advantages to these types of apps. First, they are much easier to build than native apps. Second, they work on any web capable device with nothing to install. For most use cases, they are just fine, especially for beginners. The only real disadvantage is that they aren’t eligible to be in the Apple App Store or Google Play.
