I was so frustrated when i was unable to convert 1 billion in words, i searched it everywhere but didn't find any solution for it ,then one day i was just going through m- indicator app Page and when tap the developer page , unexpectedly i found this app in the list of mobond app list , completely different from other mobond apps but this the app i want ,thank you so much

I wish it could convert and display the values in real time without any need to press 'Convert' button.

Number of digits are limited to 12....! Why....? I am, in the view of a parent, urgently in need of an app this like... I am disappointed with its limits in handling numbers with more digits.... To say trillion, quadrillion etc and their equivalents in Indian system.... Plz help.... Plz check for correctness of the grouping of digits within a large number in Indian system...
