Let’s do a brief comparison between Native Apps, Traditional Web Apps.
A native mobile app is a smartphone app that is coded in a programming language like Objective-C for iOS or Java for Android operating systems.
Native apps have the following features:
Fast performance and a high degree of reliability.
Complete access to the phone’s hardware.
Native apps can even modify system settings.
Native apps can even access the phone’s various devices and features, such as the camera and address book. It can also use the phone’s telephony features to send messages or to make calls.
Native apps have slower iterations. What this means is that it takes a while for updates to be available to users. This is because Native Apps are usually found in app stores, so any update sent by the developer has to go through the store’s regulation before it is made available to the public.
Traditional Web Apps are apps that have the following features:
Real-Time Delivery — Depending on the speed of your internet, the web app will be instantly delivered to you.
Limited access to the device’s features. So while your app may be able to access features like camera or location services, it won’t have access to your mobile’s telephony features.
Web apps depend on internet connectivity. Without a proper connection, all that you would be able to do is play with the Chrome Dinosaur.
You cannot install the web app on your device.
Any update will be instantly delivered to all the users. Unlike native apps, web apps don’t have to bother with any kind of app store restrictions.
