Very unfortunate as someone who has suffered a miscarriage and they seem to post a lot of good info ### 5/5 — So far so good! *2020-11-20, version 1.6.525* I just downloaded it today, but so far it seems perfect for women who are TTC, suffered miscarriages, going through IVF, all that. It’s great to have a place to turn to where people, like me, who have suffered 4 miscarriages, don’t feel so alone. ### 5/5 — Great App! *2020-08-03, version 1.1.415* Such a great concept. These topics are often not discussed as they are sensitive, so this provides a great platform and open forum for people. ### 5/5 — Just what I needed *2020-07-02, version 1.0.385* This app was just what I needed. Infertility is a lonely road and this app helps connect you to people who truly know the struggle. I love how you can hide pregnancy features. ### 5/5 — Great App! *2020-06-30, version 1.0.385* What an incredibly well thought out App! Finally, an all encompassing resource that helps every person in every phase of creating their perfect family! Lisa ### 5/5 — An outstanding resource *2020-06-29, version 1.0.385* Couldn’t have asked for a better app to gain knowledge from medical articles and personal stories. Really great to know you are not alone in your battles and can benefit from others’ experiences!!! ### 5/5 — WOW! This is needed! *2020-06-29, version 1.0.385* Truly a great App! Going to help so many of us who are always looking for these resources and support! ### 5/5 — Great for tracking everything !! *2020-06-29, version 1.0.385* This app has a lot of ways of tracking fertility and even journals and week to week up dates. I am not TTC until January but it’s better to start early with tracking and this is the perfect app. There are also articles and question forums of people who are currently in the journey themselves. Love love love !!! ### 5/5 — Excellent resource *2020-06-29, version 1.0.385* As a professional in the field 1in4 is an excellent resource to direct patients to for information as well as support. I highly recommend using this app! Thank you 1in4 for being there. ### 5/5 — Amazing app *2020-06-29, version 1.0.385* Incredibly powerful app on an area that more women experience than many realize. Extremely proud of the creator of this app all the work that went into what I know will be very impactful. ## Frequently asked questions about 1in4 ### What kind of content does 1in4 offer? 1in4 provides articles and personal stories related to infertility, adoption, surrogacy, miscarriage support, and fostering.
