Very simple but fun idea to play around with mobile app development and later with Fase framework. Please forgive lack of any design.
Lot's of websites have reputation systems like "karma" points, for example, HackerNews, ProductHunt, Reddit, StackOverflow. KarmaCounter can provide APIs and integrations to earn and share reputation across services and real world.
Along with "karma" points add ability to send cup of coffee or another small gift. Currently "I own cup of coffee" is difficult to fulfill.
Give users karma challenges for day, week and month like fitness apps and watches do. Track karma performance and give users updates.
If someone interested in collaboration, becoming a co-founder or taking over the project, please contact.
