Digit keeps refreshing on page transition

[bishal-rumba007]

I don't know why but the digit keeps counting every time i go to new page and come back. for example: there is a navigation bar and I have placed the digit inside of home screen and if I go to notification screen and come back it again counts up. Is it possible to only make it count up once, i.e. when app first start.
here's the image for example.
