My wife and i started to plan on starting a family at the end of the year.  I had read an article, in September, about the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> and downloaded the application.  We wanted to have a August child, so November was our conception time period.  We enter all her daily stats for September and October to come up with the best time table to try to conceive in November.  Just came back from the doctors office today and my wife is 6 weeks pregnant.  Highly recommend this app, but you must add the daily info for the best chance of conveiving.  Also recommend taking advice by googling the best way to increase  the male sperm count, such as limit alcohol intake, morning sex, etc.  We feel very blessed and hope this assist everyone trying to have kids.
