Groove is the most intuitive and easy-to-use period tracker available, and our customers LOVE it. Here’s what they have to say:

“This is what I've been looking for all along. Wish I hadn’t paid for so many other period apps because Groove blows them all out of the water. It is perfect.”

“Okay, let’s start with the fact that this app isn’t pink or covered in flowers. I, for one, like to be treated like an adult and not an eight-year-old while tracking my lady things. Second, this app represents the data wonderfully and is so intuitive. 10 STARS!!”

“We started trying for another baby around Halloween. I have heard a lot about natural family planning and looked for something that would help me track my most fertile time. It lets you do one month 'fertility style' free to start, and then it's .99 a month after that. Period tracking is free... It includes lots of extra info to read, which helped me become more knowledgeable. As my trial month went along I loved entering the data and seeing my chart grow. Being a graphic designer myself I loved all the smooth graphics. Ends up we conceived around thanksgiving, and I knew we were pregnant before it asked me if I wanted to purchase another month!! It WORKS!”

Here are just a couple of other nice things that have been written about Groove:

Customer Reviews

Great app!

I just recently upgraded to the Groove Pro version of this app and I love it! The helpful links that show you how and why this method works are super great, especially for people who are just starting out. The notes feature is awesome for keep track of diet, exercise, and anything else that will impact your cycle. Highly recommend this app for anyone who is new to the sympto-thermal method and want to learn more about their bodies!

So smart!

This app makes me feel like I actually know what's going on with my cycle and my ovulation! It is so intuitive and scientifically backed and I really am enjoying getting to know my body. I highly recommend this to anyone and who wants to take charge of her own body and have the confidence to accurately prevent or achieve pregnancy, all without hormones.

Great app!

My fiancé and I are new to Natural Family Planning, and this app is amazing for helping us understand exactly how the female body works, and what makes you fertile. It’s an invaluable tool for anyone who wants to better understand their body or their cycle. I just upgraded to Groove Pro and it’s extremely inexpensive and very useful. Overall top notch app!
