Your cycle, your way. Guided by Neuroscience.
We won't bullsh*t you
It is just another tracking app, except...
While developing Nettle™, the world’s first medical-grade device for PMS and menstrual pain, we discovered that many of the women we worked with lacked a clear understanding of how their menstrual cycles impacted their well-being. Often, the science behind their cycles was overlooked, and the emotional and physical challenges were downplayed or ignored. While this highlights a broader issue within the healthcare industry—one that tends to deprioritise women’s health and will take years to solve—we asked ourselves: how can we address this today and build a tool that equips every woman with the knowledge of her body she needs to make the right decisions for it, judgment-free?
✨ We provide you with phase-specific inspiration and educational content, to be there alongside as you get to know your body - and the science behind it. ✨
The Samphire app helps you track your cycle in detail, breaking it down by phase and educating you about what each phase is, and what’s normal for you. By monitoring changes over time, you’ll gain a better understanding of your unique patterns and how they affect your body and mind. Knowing which phase of your cycle you're in can also help you set realistic and empowering fitness, lifestyle, social, and nutrition goals.
🧠 We provide you with phase insights for your symptoms, including your sleep and activity statistics (if you have wearables/Apple or Google Health), and let you set phase-specific goals that are right for you, your body and mind. 🧠
After speaking with thousands of women about their menstrual cycles, we saw that most women think that their menstrual cycle boils down to a single day - the start of their period. However, we know that real experiences are not that clear-cut - there are a range of symptoms that will define your own individual cycle phases: the menstrual phase, the follicular phase, the ovulation phase, and the luteal phase. We built a symptom rather than a period tracker, to help you learn what your phases mean to you specifically, so that you could be in charge. Finally.

"Insane how great this is" · 10 Dec · Pkograd
This app is a game changer. It helps me understand and manage my cycles in ways I didn’t know were possible. I learn more about myself every day.
It’s a personal diary of features that paint a picture of your unique cycle fluctuations, symptoms & patterns, displayed in a way I’ve never seen before in any other app.
This was clearly built by people who have a deep understanding of what women want. Amazing. Highly recommend!

"Amazing App" · 13 Dec · Elida Sari
I’ve downloaded this app because I decided to try Nettle after struggling with PMDD. I was asked by my GP to do a manual tracking for symptoms on paper, which was helpful to see the trends etc. I the. Tried looking up any app that could do the same, have the flexibility of adding unusual symptoms, but couldn’t find any.
Until I accidentally came across this from Nettle and realise the app is as amazing as the product. I can add intensity of each symptom and even add custom symptoms. Emilé is super responsive, kind, empathetic and just overall great!
