I used Clue and it was Okay - I'm using Flo now and I like it better. Fertility Friend is good for customized tracking of symptoms. And Premom has a pretty neat ovulation test reader app.

I use Flo and love it. I find it particularly helpful when I see my doctor and can just pull up the graphs and reports for her to look at.

I have been using clue for 2 years now, it is helpful to track symptoms and it can be good at predicting even my craziest cycles.
The paid version for $12.99 CAD a year is a great option if you haven't tried it yet!
It also will give you the option for a print out version which is helpful in appointments with doctors.

Thank you. I will try them all 🙏🏻
