What are the differences between mobile apps, web apps, and hybrid apps?
Mobile apps are also usually called native apps. They're built specifically for one platform or device. Commonly, these are apps built for iOS (written in Swift) or Android (written in Kotlin).

The performance of mobile apps is usually superior to other apps, as they are developed and compiled for one platform. This also reduces the occurrences of bugs.

How to store posts in database with Ruby on Rails

This is likely relevant for you if the app you're building consists of a feature that allows visitors to create posts (like Twitter, Facebook, Google Reviews, Reddit, literally any forum, etc.) Unless you store each new post in a database, you won't be able to access that information past any given visitor's browser session.The first step to storing post information in a database with
