KarmoMeter is a lifestyle app developed by KARMOMETER LLC for iPhone users. The app hosts a weekly giveaway where participants have the opportunity to win various prizes. To enter, users are only required to provide a phone number and email for signup.

The giveaway consists of three rounds each week. Participants receive a unique number for the first round by pressing the "Start" button. Internet speed may influence this process. Subsequent rounds allow users to obtain numbers during a five-minute break by pressing the "Start" button again. The app automatically disables the button after number allocation, with the KARMOMETER team manually enabling it for each subsequent round.
