Your tracker measures your sleep, heart rate and recovery every night. We use it to find the habits and products that suit you.
Sleep aids, recovery drinks and running shoes all promise to improve how your body feels. Your tracker measures your body every night. So we use your data to choose products.
Most wellness products are chosen from adverts and other people's reviews. Your tracker data is about you, and records the sleep, heart rate and recovery those products claim to improve.
Want better sleep? Your tracker records your sleep. Want to recover faster? Your tracker records your recovery overnight. No guesswork in between.
We start from six months of your own data. Your matches are based on how you compare with your usual self, not with an average person.
Your tracker keeps recording after you buy. The same measurements show whether the product made a difference.
Pick what you want to improve, such as sleep or recovery. You can choose up to two.
We read six months of your sleep, heart rate, heart rate variability, skin temperature and activity.
We suggest habits and meals first, then products, tests or experts that suit your data.
Your tracker keeps recording, so you can see whether your sleep or recovery improves.
For each goal: what your tracker measures, what we might suggest, and how you will see progress.
The most common reason people buy wellness products, and something trackers measure well.
Exercise only helps if your body recovers afterwards. Your heart rate overnight shows how quickly you bounce back after a hard workout.
How far you run each week, and how quickly that distance goes up, tells us which shoes and kit suit you, and when your shoes need replacing.
A busy month shows up in your sleep and heart rate before you start to feel stressed. The trend over several weeks matters more than one bad night.
An afternoon slump often starts the night before. Looking at your day and night together shows where your energy is going.
Your skin temperature changes during your cycle, and your tracker already records those changes. You can plan routines and products around your cycle.
Flying across time zones moves your sleep times. Your tracker shows how far your sleep times have moved, and how quickly your sleep returns to normal.
You own a tracker and you spend money on your health. Until now, nothing used your tracker data to help you choose what to buy.
You exercise three or four times a week and your watch records every session. We help you choose what to eat, how to recover and which kit to buy.
Your calendar is full and your evenings run late. Your sleep and heart rate show the strain before you start to feel tired.
Your skin temperature changes across the month. Your routines, training and products can change with your cycle too.
Every suggestion tells you which measurement should improve and how long to wait. Your tracker keeps recording, so you can see the result for yourself.
After three weeks, your overnight recovery is above your usual level. Keep going.
