The Blood app quickly gets to know all about you, and provides personalised daily tips that go with your flow and guide you on how to benefit from each menstrual phase.

SYNC TO YOUR PERSONAL CALENDAR APP
Your period predictions can be synced with third-party calendars (such as Google Calendar or iCal) with just one tap for an overview of what your schedule holds – and how your period may come into the picture! No more switching between apps and struggling to keep track of things. With this integration, you can easily get a glimpse of your flow together with other events so that you can plan your holidays, dates and other activities – worry-free!

Taking a user-first approach, we’ve given our app a brand new refresh! There’s so much to discover about your cycle and health – this exciting interface makes tracking your period, viewing countdowns, checking on fertility, and getting support a fuss-free and fun experience that you’ll want to keep coming back for.

It used to be good. Now wants me to log in every time and the main page which tells how long til my next period asks me to input my first period, while the calendar already has several logged. I see other people have mentioned similar issues in reviews since the last update. It's no longer reliable and hassle to use. Switched back to my previous tracker.

I personally like blood because it keeps me notified when I'm gonna have my period, I know that some people have eneven(idk how to say) type of menstrual cycle(including I)but it still been helpful for me cuz i will at least get my period 1-2 day early/late but not the exact day. why I think blood is rlly good cuz it helps me to make a vacation plan without dealing with sudden period. also, there some tip for young teens. which I think it was helpful for me too.

this app is good, not for irregular. the predicted period dates don't change with each day my period is late. ie, it expects me to get my period on a certain date. my period doesn't start and is late past those dates and predicted dates are now in the past. instead of seeing the actual day of cycle, it is calculating new cycle already, even if my late period hasn't been tracked just yet. in Flo, if late it would show the upcoming day as a predicted start and show correct length of actual cycle.
