Know when to train, how hard to train & when to rest in order to optimise health, fitness and athletic performance.

A 60 second measurement each morning will tell you how stressed, recovered and ready for training your body is. Using heart rate variability (HRV), resting heart rate and lifestyle factors, such as stress, diet, sleep, and more, ithlete delivers a truly personalised training recommendation that anyone from a recreational runner to an Olympic athlete can use.

The many benefits of having this information (quite literally) at your fingertips include:

- Make the most of every training session
- Manage recovery
- Optimise fitness
- Enjoy guilt free rest days
- Avoid overtraining & injury
- Balance workouts and lifestyle demands
- Improve health, fitness and performance

Getting the right balance between training and recovery is a challenge, even for experienced athletes. Remove the need for guess work by using ithlete and base your training on an objective measure of fatigue and recovery. You will reap the benefits in fitness and performance.


Heart rate variability is a proven window into the body’s nervous system, going beyond a simple resting heart rate (RHR) measure. Training is all about stress and recovery and a hard session will lower your HRV score. By using ithlete to monitor training stress you can adjust sessions according to your body’s current readiness to train, improve and perform.
Simply take a 1 minute measurement every morning and follow the colour coded training recommendation: train as normal, train light or take a rest day.

The ithlete HRV app requires additional hardware.

Users will need either an ithlete Finger Sensor OR a compatible analog or Bluetooth Smart HRM strap. These are all available from www.myithlete.com/products. Please see the website FAQs for a full list of compatible models and purchasing options.

Please also note that this HRV app is NOT a heart rate monitor app, which people use during exercise. The ithlete app is an app that uses heart rate variability to indicate your state of fatigue, recovery and readiness to train following a 1 minute morning measure, and it is not used during the actual exercise.

Helpful recovery tool

This is a great tool if your training for an event. I use the finger sensor every morning to get a snapshot of my cns. More than a few times I've adapted my workouts because of my HRV results ( if it's low I'll do light cardio or just scale the workout back, if it's really high I'll find a workout that really pushes me). It seems to be very consistent & the finger sensor makes it simple & quick to do first thing after awaking. The only reason I didn't give it 5 stars is I'd like to see the actual numbers it measured & I'd like to be able to slow down the visual breathing tool.

Helpful if you can get it to work

This is a great concept IF the app were able to detect pulse for a solid 55 seconds. More than 70% of the time it loses connection to the thing measuring pulse before the time is up, and the whole process takes on average about 5 tries with varying levels of success. This is pretty consistent throughout different measuring tools - I’ve used their ECG receiver, finger sensor, HR monitor, and a Under Armour HR monitor. Actually, the tool that worked the most often was the UA HR monitor, but still around 3 tries every time to get it to work. I wouldn’t recommend any of the other tools they sell.


Trouble detecting pulse

Every time I use this, I need to make multiple attempts to get the app to accurately track my pulse for 55 seconds. It always stops me at least once and makes me start over due to lost connection between my HR monitor and the app. It’s really frustrating, because it’s a great concept, but it is difficult to do every day because it turns into a whole process with several attempts each time I do it.
