Keen's popularity comes from its similarity to IRL psychic appointments. The application even allows users to "fall in line" for available online psychics. Keen also screens the best psychics applying for their platform as a quality assurance measure. Some users have complained about the quality of some online psychic services, which is not uncommon even at in-person readings. In addition, some energies do not match, so it would be best to find a partner in tune with your spirit.
