Was great but…

I loved this period tracker. I’ve been using it since it was launched. I loved the ease of use and the look of everything and the focus on hormonal health… BUT. Why has everything aside from nutrition always been accessible and now I have to pay a subscription to get insights?! I don’t understand and I’m thinking about uninstalling. I don’t want to deal with the hassle of getting bugged to pay money and it doesn’t seem right that certain components were free and now they aren’t.

Good when it works

UPDATE: So after writing this review and putting in multiple tickets with their support I just now get an email stating the issue was fixed. What about paying for a year of a service I lost out on several months of? I’m so fuming I refuse to use the app even though I paid.



I mistakenly purchased a year subscription. I couldn’t get my money back and that’s fine I came to terms with it because I like the app. However, the app hasn’t worked for months now. The loading bar won’t move unless I uninstall the app and reinstall it. I have contacted support twice and gotten no response. I’m very frustrated because I want to like the app

changed my life - ruined by a paywall

EDIT: the message below was my honest review of this app a few years ago… i found it during the height of my PCOS which we know is now called PMOS and it helped me get in tune with my cycle so i could start feeling more comfortable in my body. after years of using the app, they have decided to put almost every feature, now including the insights, behind a nasty greedy paywall. this was done before a while ago and i remember being so disappointed then and i continue to be disappointed. it is almost impossible for women to have access to effective and validating healthcare and while i am completely aware that this app is not a substitute for medical advice, it is still instrumental in helpful women understand their cycle and heal their cycle through information, nutrition, and exercise. i am several disgusted by how greedy and money hungry this platform would be to exploit women who are hoping to understand themselves a little more. shame on you.

original review: being someone with a uterus and menstrual cycle can be a very confusing and lonely experience even though most of it is quite universal. this app has changed my life. i’ve wanted an app where i can track which phase of my cycle i’m in beyond just menstruation and ovulation. besides that wonderful feature, i find the best part of the app are the daily insights. it’s always reassuring to read into why im feeling a particular way every morning i wake up. this morning i just felt incredibly sad and couldn't stop crying and my insights today were so enlightening in explaining my body, my hormones, and how that manifests in my energy, mood, etc. i love this app so much.

Disappointed

Update: I have now deleted this app. When you first look at the app it looks like it’s going to have a lot of features that are customizable. But it’s not. If you set your cycle to 28 days and your period starts a day early so you adjust the calendar, all historical data. Why would anyone want to do that? If you’re trying to get pregnant or going through perimenopause you don’t want your history changed. You’re trying to TRACK it.

Further, now all of the insights to mood, your body etc. are behind a lock and require a paid subscription.

The people running this app think they’re being smart by giving full access for free and slowly reducing the free inclusions. For some reason they think you’re going to now pay for the app. Wrong. It’s market manipulation and I won’t have it. There are better apps that are free and actually work better

Original review:

I have had a free membership to this app since its inception. Recently, the nutrition section is completely behind membership permissions and is no longer viewable. There have always been parts of the app that a paid membership was required to use. That’s to be expected. But it’s very disappointing when features that were once free are no longer. That pretty much reduces this app to keeping track of your cycle and a bit of peptalk. Hardly worth logging in.

Very frustrated with new updates

I have been using this for years now, and have been paying for the premium subscription for most of that time as well. With recent updates, my calendar got messed up somehow and changed the dates of my period recently. I am now for some reason locked out of viewing recipes, workouts and even the tabs that tell you about your body, mood, path etc. despite paying for a yearly premium subscription that is set to renew in December. I emailed support a week ago and have not gotten any response so here I am writing a review. If this doesn’t get fixed I will most certainly be canceling my subscription because what’s the point if the calendar isn’t accurate and I can’t access anything else despite paying for it. Very disappointed with this new AI, as it seems to have made this app worse, not better.
