There are all manner of addictions that can be "assisted"/made worse with technology. The solution isn't in the technology though - it surely starts with the person??

Should my toaster warn me if I use it too often in an hour? I might put weight on with all that toast I am eating.

Should my coffee machine warn me if I make too many coffees? I might have too much caffeine and suffer heart problems.

Should my app warn me if I use it too much? I might be a workaholic and spend too much time in Excel.

Who is in control of the toaster? Me or the toaster? Who is in control of the coffee machine? Me or the coffee machine? Who is in control of the phone/PC/app? Me or the phone/PC/app?
