  Premium & Spam 👎🏾

  I actually have been using this app for years, and I had loved it! I enjoyed the insights and the recording aspects. However, many features are now locked behind a pay wall. What I HATE the most are all the pop-ups. You literally get spammed by the app whenever you log in. Which is why I now prefer to just use Apple Health. I comeback to the app due to nostalgia but I’m quickly reminded it is NOT what it once was…sadly

  Great App and Support Team

  Wonderful app and customer service! I purchased a free trial of Premium and was billed after it (having forgotten to unsubscribe), and I quickly emailed the support team for a refund and cancellation of benefits at 1:00 in the morning. They responded in a matter of minutes with a full refund! The app itself is amazing as well, with and without Premium benefits! Very helpful!!

  Extremely inconvenient

  Each time I open this app, it tells me to subscribe with an offer, and I have to 2-3 different buttons to exit out of the offer just so that I can use the app. It shouldn’t have to be this way. I just want to access the app free, if I wanted to pay for the extra features which seem unnecessary to me, I would.

  Expensive, but helpful

  I enjoy this app. I pay for it to track my cycle. Concerns/Areas to improve: 1. I’m worried they are apart of the lawsuit that sold our information, but I guess since the government watches us anyway, it doesn’t matter. 2. It would be great if the notifications could be adjusted. 4-5 notifications with irrelevant things isn’t helpful, perhaps letting us adjust the settings for what we want to see. 3. My cycle can be tracked, but it makes assumptions based on my inconsistent cycle. Telling me I might have PCOS each week and not letting me adjust that away can be frightening to the wrong audience. I would suggest changing that wording, or at least allow patients to remove the alert if they have been tested and confirmed no PCOS. Helpful/Good: 1. Overall mechanisms of the app are easy to use, and newbie-friendly. The environment of the app can feel like a safe place sometimes, which is helpful for those that view this as a sensitive topic, or need discretion. 2. Articles do feel helpful sometimes. I would add more resources, and add more ways to explore more research about women’s health. For those without a uterus using the app, it could be helpful to see those resources to continue to educate about each process. 3. The calendar function is helpful, and extremely useful. Find a way to discreetly add it to the Google Calendar. (Or if you have figured it out, let me know how to merge them).
