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.

Ratings and Reviews


Essential training tool

This is essential to training effectively. Great app


Good App

I have been using ithlete for a couple of years. I use it to determine my training level each day. The app syncs with Training Peaks reliably so that my data is transferred each day. It doesn't always seem to sync well with Garmin to import my training load. It would be good if I didn't have to login online each day to see my training recommendation - I can never login from the app. The app itself could do with a facelift IMHO.



The app has bugs! Firstly, sometimes at the end of a 55 seconds ready the app just suddenly turns off. This happens 2x pw. Secondly, it it can take forever sometimes to get the green button to start. I use this app daily alongside sweetbeat and hrv+, and unfortunately this is the poorest. Please fix, as I like what your doing, but bugs are letting you down big time! I'm on a 4s if that helps, but if the other apps work fine on a 4s I would guess yours should too!
