Basic question

HI Guys ,

I am new to app development . I am using the Ionic framework to develop an app. What I would like to know is if I develop a simple app that has all the information in the app and has no remote database interaction how does the updating of the data work.

Lets say I change some wording does this mean the users that have the app loaded on their device ( IOS and Android platforms) have to re download the new version of the entire app ?
