Is there a way to show disk usage (and disk space left) prominently in iOS by issuing alerts when treshhold is met?

I wish I could see my disk usage (and remaining disk space) like "10GB/256GB remaining" prominently every time I use my iPhone (iPhone 13, iOS 15) much like I can see the date/time and battery % every time.

Ideally I can set a threshold, below which the OS will alert me rather than depend on the OS to decide that.

Is there a way I can do this on iOS 15?

Is there a way to show disk usage (and disk space left) prominently in iOS and/or macOS, and/or issue alerts when treshhold is met?

I wish I could see my disk usage (and remaining disk space) like "10GB/256GB remaining" prominently every time I use my iPhone (iPhone 13, iOS 15) or my Mac (macOS 10.13.6, A1990), much like I can see the date/time and battery % every time.

I also wish I can set a threshold, below which the OS will alert me.

Is there a way I can do this? I need this urgently for iOS 15 first. It will be a bonus if there's a way to do this also for macOS 10.13.6.
