(I am Indian and live in India fwiw) How about 10k Rs to be donated to the winner's favorite charity? How about 1 January 2022 as a settlement date? If the app is still mandatory on that date, I win, else you do.
I will gladly take you up on that :) Bonus that whoever wins, money goes to a charity too.
Done!
I am not a gambler, but let's say $5 if you really wish to get money involved. Or a bottle of scotch.
