Great app, but.. “Risk of Pregnancy” ?

Dear Eve,

I love your app. It’s helped me manage my cycles every month. It’s been very accurate recently because of all my previous logs. However, I noticed something today. Maybe it was there before, and I’m just seeing it for the first time, but I could help but notice how the notification states “risk of pregnancy” followed by a percentage. The percentage system is great. I can understand the use of wanting to know when you would be more likely to have pregnancy. But for me, I’m someone who one day would like to be able to get pregnant and I just feel that the choice of words for that percentage only covers a certain group of people who might actually be fearful to be pregnant, but not the woman who are striving to one day raise their own child. The very definition of “risk” is a situation involving exposure to danger or “to expose something of value to danger, harm, or loss”. For me, I don’t view pregnancy as a “danger harm or loss”. It’s a miracle. Because I am but only one woman trying to have a baby one day. I use you app to track my periods, yes, absolutely, and maybe that’s all you’re about, but if you’re so much more than just a “period” app, and more a “woman’s app”, wouldn’t you also be for pregnancies as well? My suggestion is replace the word “risk” with “probability”. That word is more neutral. It takes neither side of the battle and it’s factual. “Risk” sounds very one-sided minded. Thank you for your time.

Trying To Conceive

I absolutely love this app for keeping track of my periods! And being able to talk to all the ladies! However I wish there was an option just for those of us who are trying to conceive, because a lot of the cyclescopes and other parts are mainly directed more so at the women who are on either on birth control or not trying to conceive. Just for example, if it’s fertile week it’ll mention about taking precaution since you could get pregnant. It would just be nice for us women who are trying month after month, to have a little bit of encouragement around that time! and also maybe some information on whats going on with our bodies if we did actually conceive, but the pregnancy didn’t take. My dr told me that happens more often than we realize and will think its just a heavy period. Just like it does when it gives us all the helpful information on all of our moods and hormones and all of that during the cycle scope! That’s my only opinion to make it better. Other than that I cannot complain, I enjoy a community of women being able to just talk about all of our women issues and not have to be embarrassed or ashamed. I love Eve, I also have a couple other apps, but I can’t even use those ones like I can Eve, because they’re primarily for pregnancy. Which obviously after TTC for 5 years only keeps me looking and hoping. Anyways! Thanks Eve!

Hi Brittany! Please check out our app, Glow, which was created with the intent of helping women conceive!

Looks good.

I haven’t gotten my period yet, however I’ve been looking at different apps. This seems like a very high quality app. The only thing I wanted to point out is that this app says its for 17+, however I’m sure many girls who have recently started their period could use this. I understand that there are questions concerning sex, however I believe that girls who have gotten their period have already had the talk about sex. It should not seem inappropriate or gross for a girl to see, and I doubt there would be an issue concerning it. There could be this explanation in the game description for caution. There’s also a large chance that girls using this app would be masturbating, which is completely okay! I’m very happy that this app includes that detail, and I don’t think young girls should be excluded because of it. Also, many girls under 17 have sex, so questions like those would be necessary for even girls under 17. I just thought I would point that out. Anyways, the app seems wonderful. I’m not sure if this is in the app, but I think reminders for using protection during sex and that infertile windows should not be used to determine when to have sex, as it is is still very possible to become pregnant even when not fertile, should be added(if not already included.)
