Marriage is sacred. However, violence against women is currently prevalent in all countries, with 35% of women worldwide experiencing physical violence, including intimate partner violence. Mutual understanding and timely communication is a way to avoid domestic violence, hence the design of PROMISE.
PROMISE is the ring to monitor the health status of a couple. It will detect when you are in a poor state of health or mood, and flash vibration on your lover's ring as well as the corresponding APP alert so that he/she can take more care of you, communicate in time, and reduce conflicts.
