In some apps, when navigating to a page that has number showing one or more different numbers it will animate from zero to the final number in about 0.5 seconds, counting upwards. Till example if the final number is 15, it starts on zero, 1,2,3,4,5,6,7,10,11,12,13,14,15 changing the value every for example every 100 millisecs.
Is there any user interface reason to do this? Is it because it looks cool, or the user will direct more attention to reading numbers that were animted instead of static when entering the page? Is it reserved for numbers with specific meaning, like it does it make sense to do this animation to a phone number?
(If anyone finds an example GIF, its greatly appreciated)
