### 5/5 — Awesome

*2020-10-23, version 2.33*

I’d like to thank the developers for caring about women’s health! You’re doing a great job, carry on! My story with VIO began a year ago. It was my mom who recommended it to me as a highly reliable app. Before that, I didn’t depend much on watching the cycle. Until my husband and I decided that the time to enlarge our family came...we were eager to have a baby, but our efforts were of no use for quite long. Then I realized I needed to take my health under control and watch the cycles carefully. Using VIO, I learned how to pick up the most fertile days and we did it! Now I’m 4 weeks pregnant and we’re over the moon. But I’ve not noticed any difference in the app usage during pregnancy yet...btw are there any? And I wonder are there any adjustments for users after childbearing? Anyway, I’m looking forward to a new version and the features it’s going to bring forth (as you’ve understood I’m in anticipation of the pregnancy and post-pregnancy mode).

### 5/5 — Amazing

*2020-10-23, version 2.33*

My friend is excited about the app and she recommended it to me, saying all those tips and insights and trackers will help me normalize my life... I’m interested, indeed, especially after reading reviews and descriptions, holding much promise btw. But I have a kind of problem so just need to clarify several moments...Will your app be of help if I have irregular menstrual bleeding twice a month? Will it manage to calculate the cycle and fertile windows?? It’s of great significance for me. I’m constantly suffering from irregular bleeding. The cycles are very painful, I have to stay in bed for a couple of days. And that happens twice a month!! No application helped me yet in calculating ovulation...I’m ready to buy this one but tell me whether there will be any use to me, please… P.S.: Don’t advise me to consult a doctor as I do it regularly.

### 5/5 — Like this app

*2020-10-23, version 2.33*

I’m satisfied with all the features included in the app. But I’d rather focus on a different thing I do like about it - its subtle interface. I use the app every day, so it’s important for me that it doesn’t annoy me. I got irritated with the design of apps I’d been using before VIO really fast (I won’t mention their names to be on the safe side). At first sight, I was OK with them. After some time passed, I caught myself thinking that those colors were getting on my nerves or that a certain app had a perfect design for teens, you know, but I needed something more pleasant to look at without those childish characters or whatever. I do appreciate the pleasantly appealing interface of VIO, its usability, and its seriousness of approach to women’s health. I’m happy to use it, thanks! You deserve 5 stars!

### 5/5 — Great app

*2020-10-22, version 2.33*

I’m running my own business. Due to my lifestyle, I can’t spare so much time to put all the data in daily. So I can’t use the app to the full, unfortunately. But the features I use are really helpful. The menstrual bleeding, ovulatory period, and fertile windows are always evenly calculated. For me, as a businesswoman, accuracy means everything! I need an app I can rely on 100% so that not to get into trouble during business trips but rather to feel confident during meetings. I believe I’ve found the one. I already have a personal assistant in the office and now I have another one on my phone. I can entrust VIO secrets of my private life and it helps me keep my health condition under control. But I’m sometimes irritated with the reminders of the features I don’t use, they are bothering me, often distracting from my business. I’d appreciate it if I could unable them. Nevertheless, I recommend this app!

### 5/5 — Good app

*2020-10-22, version 2.33*

I downloaded VIO 6 months ago. Though I’ve been using it for not so long, the calendar has perfectly adjusted to my menstrual period and it always produces accurate predictions. And this is I guess the very thing we all expect from such apps. It really makes my life easier, so, girls, you should definitely try it! By the way, the idea with a personal assistant and useful tips is excellent. I find it rather curious and useful to read them. Once I followed the recommendation and, as my gynecologist said, it prevented me from health complications. The thing is I got pregnant :) But I had no clue about it, only mild symptoms like headache, nausea, and exhaustion which could be indicative of some other illnesses as well. I didn’t think of pregnancy and did all the hard work, almost leading myself to miscarriage... The app suggested I was pregnant and after reading those useful tips I decided to see a gynecologist what saved both my and my future child’s lives. So thank you!!!

### 5/5 — Awesome app

### 5/5 — Excellent 🤟

*2019-12-28, version 1.2*

At first I was skeptical, but this app is terrific! I won't ever uninstall it, believe me!

### 5/5 — 🤙

*2019-12-27, version 1.2*

Now I know for sure when to expect my next period without any doubt.

### 5/5 — 💫

*2019-12-26, version 1.2*

It offers cool, useful tips written by real doctors. I trust and recommend this app!
