An excellent tool for gauging workout intensity... Probably the closest thing we have to a broad indication of overall health - The Telegraph

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 recovery enablers, 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. For more about heart rate variability see

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 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.

Very good

This is amongst the best of the HRV monitoring apps out there. Its beauty lies in its simplicity. The basic app provides a simple level of analysis and feedback which is perfectly useful but where the real power lies is in the iThlete Pro package. Although Pro requires a subscription it provides really useful additional layers of analysis to help you understand the influences on your HRV measure. The UI of the app is a little clunky but works fine one you are used to it.

Well worth it if you want to understand how you are recovering (or not).

Useful app

I've been using this app for a while now and feel it's very useful as a training tool that gives me an indication of actual physiological fatigue. However, I was put off using the app for a long time as I didn't have a HR monitor and didn't want to pay the rather high cost on the iThlete website. I came across a second hand HR monitor that wasn't on the list of compatible devices and it worked and I've been using them in conjunction since.

Easy and useful training aid

The finger sensor is easy to use and works well. It's been a useful app, even at the basic level, to help me keep an eye on my training load so I work hard enough but don't push myself too far. I upgraded to pro for a while and found the tips and extra detail really useful. Good dashboard. Big thumbs up.
