I tested my current relationship, I haven't bought the other choices so in just using the Zodiac, Scorpio-Cancer. It came out at 95% and with the description is was pretty close to perfect for the accuracy. I got curious and check my last two serious relationships I had, both of which were not good and one of those being very horrible and emotionally damaging for me. Scorpio-Leo was the horrible one and what the description said was accurate. Definitely never should've had that relationship, it was a fail before it began. The other one, Scorpio-Virgo, wasn't so much bad as it was that the relationship should've stayed friends more than likely. The end results were pretty spot on too. Definitely better friends with that one. Considering buying the other bits for the app to have more to add to the Zodiac results. Definitely worth the free download if nothing else.
