Understand changes in your HRV and resting heart rate against your own baseline, with your recent training and recovery alongside.
Your watch reads your heart rate all day. NOYU turns it into a battery: sleep charges it, workouts and stressful stretches drain it, and you can see what’s left for today.

Late coffee, travel, a night out. Add what happened around your readings and see which ones keep coming before a worse night.

It’s like having a nutritionist, a well-being therapist, and a fitness coach all in one place!
It’s picked up on patterns and made suggestions I wouldn’t have thought of myself.
There is nothing else available that fits my needs.
I asked NOYU why, and it turned out I was significantly under-fuelling, which apparently pushes up injury risk too.
When I had a niggle in my knee, NOYU reworked my week so I could rest it.
I have felt so much healthier, physically and mentally, since I started using it.
NOYU makes messy, scattered data much more intuitive and engaging.
In my case, it flagged that I was training in my grey zone and since then, my VO2max has increased from 47 to 50.
It caters to senior people in an easy-to-use format that is easy to navigate.
On longer runs I’d fade badly in the second half.
Every morning it tells me how to approach the day, based on my sleep and that week’s training load.
I love that it tracks my sleep debt and tells me when to go to bed, in line with my body clock.
NOYU makes it so much easier, and I’ve already found a few things that make me feel better and have more energy in the mornings.
It knows how I slept, what I ate and how I’m feeling, then tells me how to best train today to achieve my goals.

A lower HRV reading after a hard session tells a different story from one after a restless night. NOYU brings your training, sleep and daily context together to help you understand what a change could mean for you, and whether to do anything differently.

Log a meal with a photo and see your day against targets that move with your training. NOYU suggests what’s worth changing.
