Training Today constantly monitors your Health Data from Apple Watch to determine your readiness to train (RTT) each day and throughout the day.

Training Today can help you stay safe from overtraining injury or let you know if it’s the best time to work hard, take it easy, or have a rest day (yes please).

Developed with British Triathlon Coaches and tested on athletes of varying ability, we have taken a holistic view of your life by using the advanced capabilities of Apple Watch to monitor your health 24hrs a day and process that data to create a simple accurate readiness to train (RTT) score to help you reach your training goal.

Key Features

* Calculates your readiness to train (RTT) score automatically throughout the day.
* Presents a multi-day chart showing how your score is changing.
* Using the Digital Crown you can scroll through previous RTT scores on the chart.
* Runs independently on Apple Watch, no need for iPhone to be present.
* iPhone companion app also shows your current RTT score and tutorial.
* Full support for all complications means you can quickly glance at your watch and see your current RTT score at any time.
* Because each athlete handles variations differently, you can fine-tune the recommendations and chart using adjustable “smoothing” and “intensity” settings in the iPhone app (with in-app purchase)
* We use Heart Rate Variability (HRV) and Workout detection and our own algorithm to determine your RTT score. For best performance wear your Apple Watch as much as possible and overnight if you can. You can force a new HRV reading if needed by using the Apple Breathe app. Using two Apple Watches on the same Apple ID account is fully supported (though it can take a little while to sync the data between them)
* Automatic filtering of outlier data (e.g. very larger variances in data)
* Workout detection - we detect when you have completed a workout logged to Apple Health and show it on the chart. Tap the screen when you see one to get details of the workout and better understand the impact on your RTT score.
* Post workout prompt - if you have completed a workout but we don't have a recent HRV reading the chart will show an exclamation indicator (!) prompting you to use the Breathe app to get a new reading so we can update your RTT score and chart.

NOTE: Both iPhone and Apple Watch apps need access to HRV & Workouts in Apple Health. You should be prompted for this but you can check on Apple Watch using Settings > Health > Apps > Training Today and on iPhone in Settings > Health > Data Access & Devices > Training Today.

What’s New

Version 1.6

Development improvements mean that we now do a better job of keeping the iPhone and Apple Watch RTT scores in sync at all times.
Ready for watchOS 8 and Apple Watch Series 7.
We have moved the Smoothing and Intensity settings to the iPhone app (available via the extra charts in-App purchase) to provide more clarity and accesibility and to keep the interaction on Apple Watch nice and simple.
Improved the HRV display accuracy in the 60-day chart (available via the extra charts in-App purchase) so it now shows one decimal place.

Absolutely Amazing App

I gave this app some time before putting this review out.

I feel this is the perfect timing to talk about training today as of last week I came down with Covid and I didn’t expect the see what the app displayed.

My body went into complete shock with the virus and training today showed my score as 0.0 and recommends to take a break! Even tho I am recovering and 80% recovered the app still recommend I go for a very gentle walk!! It’s incredible how it knows how my body feels and it’s a absolutely spot on. Even prior to falling sick upon waking up I have a score of racing and again the assessment by the app is on the ball. All in all an app that I can rely on not to exhaust myself in training and take the right beaks for full recovery. Well done team

A very useful and helpful app

At last a way to understand and make use of all that HRV data! This app provides a useful indication of how well I’ve recovered from previous workouts so I can modify my workout plans for the week or maintain awareness of how I feel during workouts so I can push myself (or not!) accordingly. I think paying for the extra charts is well worth it for those like me who appreciate geeking out 🤓. They could do with making the functionality and UI a bit more self explanatory/intuitive but knocking a star off just for that would be disproportionate to the value of what the app offers. I hope they continue to improve on it. Well done!

Great app but still has more potential

Absolutely been loving the app, I’ve been looking for a whoop like Experience on the Apple Watch and this has delivered. However, the app could improve a bit more with having a questionnaire to assess your perceived exertion or taking into consideration your sleep data. With that being said, the app is fantastic and paying the small fee for the graphs in my opinion is a no brainier. Love this app so much, I’m constantly looking at it during the day as a form of assessing my physical condition. Worth the purchase and can’t recommend enough🙂
