When calculating fertility for pregnancy with natural family planning, Cycles takes advantage of scientific research that’s more accurate than the 'rhythm method' of yesteryear and has a real-world failure rate comparable to that of condoms. Even so, this app is designed for informational purposes only and should not be used to prevent pregnancy.

Good for estimates

Had this app a few years and find it really helpful to see roughly where I am on my cycle.
Love that you can edit the length of days for your cycle etc and make notes on specific days.
The only thing that isn’t so helpful and I would love to see changed, is how previous dates that have already passed are automatically changed if you amend current or future predictions on the calendar. For example, if I think I’m ovulating I’ll check the cycle ‘wheel’ to check it lines up with the prediction of what day that’s due to happen so that the day I start my period is also likely to be accurate. However, in changing that wheel it moves the Previous date(s) of when my period started last month(s), making it impossible to keep a log of how long Each cycle is on the app’s calendar. So I keep a separate notes list of dates for this.
It doesn’t make sense for previous dates to be moved automatically.
Is there a way around this?

Not as good as it used to be

I used to love this app, I used it for years and found it great for estimating dates for fertility treatments, really handy and easy to use. In the time I was pregnant the layout and functionality has changed, it’s now clunky and difficult. As my cycle has been disrupted from pregnancy and breastfeeding it has decided I have a 58 day cycle, despite my last cycle now being back to around 30 days. As a result when I check the app (used to let me see at a glance where I am in my cycle) it now tells me I’m not due for another 38 days despite only started my last period 2 weeks ago. There’s no way to change this - unless, maybe I pay for it, which I’m unlikely to do with how clunky it’s become. Really disappointing.

Great app

I do love the app but the update has a few changes features that I don’t like ... hence the 4 stars.

I like how you can keep track of the period and love the cycle view ... but the new view of the cycle and the calendar is a bit confusing.

I lost my years worth of notes due to an update & lack of back up on the Cycles system so that was a big disappointment.
