The love meters at Astrospeak.com and Love-Tester.com both provide a percentage score alongside a written explanation. Love Tester also has ten other love tests including a long-distance relationship test, a crush test and a soul mate test as well as a love horoscope. Simpler tests exist at Love-Meter.net and Prokerala.com.
Love calculators, or love meters, work by taking two names (and possibly more information) and, using a sophisticated algorithm, matching each partner with love, romance and relationship traits. The percentage rating is a reflection of the amount of traits that the partners have in common.
By far the simplest love meter is at Prokerala.com, with a simple design that takes two names and genders, returning the percentage of romantic compatibility that users then share on Facebook. Prokerala also has free daily and monthly love horoscopes based off of partner's zodiac signs.
The most advanced love test is at Lovetest.com. This process uses the full names, genders, ages, zodiac signs of two people, as well as 43 relationship questions, to calculate compatibility. The site also publishes a love test prank, where users send friends custom love test links, receiving email results. Lovetest.com also has a love fortune teller and a mobile app.
