Because Pokemon Go has a bug on the iPad version and I cannot see the number of Pokeballs remaining to catch a Raid Boss (due to aspect ratio of iPad about 4:3, not the same as iPhone's 16:9), so I want to use the 2-app-side-by-side method to see if I can somehow change the aspect ratio of the app.

So I either run Pokemon Go and slide in a Safari, or run the Safari and slide in Pokemon Go. (By running Pokemon Go, and then slide from bottom up of the screen to see the dock, and then touch-and-hold an app and move it to the edge of the main screen area).

Either case, I see Pokemon Go running as a full screen app. Is it true? Some apps cannot run as a side-by-side app but must remain full screen?

Yes, that is true. The app must be compatible to run side-by-side - and if the app is not, there's nothing users can do about it other than encourage the developers to add the support.

  • so in a way it is not "black box"... meaning that the app can't be running in an environment that the iOS provides. If it is a black box, then an app doesn't need to be specially made into able to run side-by-side, but is just made into displaying in that given region (such as by iOS resizing the window to fit into the side-by-side panel) Jan 17, 2018 at 13:12
  • Your statement does not really make sense. No one is claiming that apps are "black boxes" - nor is being a black box a requirement for running in an environment the OS provides. And even if it were a "black box", apps still would need to be created so that they support multiple view port sizes in order for that to work. The reality of this is that there's a property list inside each and every apps on your iOS device. When trying to side-by-side an app, iOS will check if this property list contains a key that tells that the developer okays side-by-side usage. If it is not there, it won't work.

  • what you are saying is poor software design. If it is good design, it should be able to run in any reasonable screen size just by resizing. Given a square region that is 768 x 768 on the iPad, if the app runs well full screen on an iPad, then just resize this app to be 768 x 3 / 4 : 768, which is 576 x 768. Doing so is really simple in the OS, and it allows all the full screen apps to run in any region without needing any special change. Jan 18, 2018 at 3:19
  • It is your opinion that it is poor software design. I do not agree with your opinion. It reasonable to allow the developer of the app to decide if their app is designed to be run simultaneously with other apps and at a different view port size. The app developer can then decide if that is a good user experience, or if they want that not to happen to avoid user's having difficulties due to these circumstances.

  • if the OS is robust enough, it should allow simply running of an app in a certain dimension in another different environment. iPhone-only apps being able to run on iPad with the iPad showing it in the iPhone aspect ratio and with everything running perfectly is a good example and is good design. Why you don't agree with good design is beyond comprehension. Jan 24, 2018 at 0:41
