I have been using this app for over a year and I love it. Use it to track my periods and avoid having sex on my fertile days at first, then to determine my fertile days for trying to conceive. Worked like a champ for both - didnt get pregnant when we werent trying, then got pregnant on the first try. Especially like pregnancy mode bc the calendar tells you how many weeks/days you are. You can look at future months and plan accordingly. My other pregnancy app doesnt have a calendar like that so this is very useful.
