It depends on what you mean by re-rendering. I would use the Microflow timer widget to trigger the nanoflow after a certain time so you can refresh the object with the counter. This way you do not re-render the whole page but only that part of your form.

Hi Jayasree,
I would suggest taking a look at the app events widget found in Native Mobile Resources. It has a timer functionality that can trigger a nanoflow either once after a delay or in a loop with a delay between each nanoflow trigger.
From what you are describing, you should be able to update a value or create a notification based on the nanoflow that gets triggered.
Hope this helps!
