It's Valentine's Day. We at Android Police won't belabor that particular point, but the family-focused social network provider Life360 will, because they've made a serendipitous purchase that just happens to coincide with this weekend. The company has purchased Couple, another targeted social app that goes after, well, couples. The announcement was made on Friday, but it's surprisingly lacking in any mention of a price, because huge denominations of money that aren't attached to large vehicles or small carbon concentrations aren't very romantic.
