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 (Just press firmly on the Apple Watch screen to get to settings)
* 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 1.1.5

*** Workout identification ***

We now detect your Apple Health workouts and show them on the chart so you can better understand what is affecting your RTT score. Tap the screen to see details of the workout as you scroll through the chart with the Digital Crown and when you see the workout indicator.

If you have completed a recent workout but Apple Watch has not yet recorded your HRV following that, we now show an exclamation Indicator (!) which will prompt you to use the Breathe app when tapped, so we get the most recent data for your chart your RTT score is up to date.

Excellent so far

I’ve been trying to incorporate HRV into my training for a while but so far available apps have insisted on specific hardware and/or been too top-heavy looking for manually inputted correlations with other metrics. Many of the latter exist in other app ecosystems that only partially share data with each other or with apple health. I’d frankly rather be out riding my bike that any more messing around with this, and have been waiting for a solution that just used what’s on hand in apple health already. I get that it’s not as good as standalone hardware, and that ideally HRV would be measured at a fixed time, like every am etc., but it’s still data, and after looking at it for over a year (and using Breathe first thing each am) it does correlate with how I’m feeling and my performance.

So, 5 minutes with this new app and using existing apple health data it perfectly predicted in retrospect what my week has been like, including having felt fantastic on the bike this morning, which was correlated with a 10/10 peak performance prediction.

Not much in the iOS app itself, but the watch complication/app is perfect. Get it. Oh, and I’d be willing to pay for this BTW.

Useful and Easy

What a nice little application. I’ve tried various HRV apps to track cycling and CrossFit recovery (or damage depending on how you look at it) and all required some intervention on my end. Most were simple but I just couldn’t stay compliant.

Training Today is easy, just wear your watch and keep an eye on the complication.

The app recently showed that I was race ready and that day I set multiple PR’s and top ten finishes on segments in Strava. Awesome for knowing how hard to push and when to rest.

Nice little update that just included workout data in to the RTT score. Looking forward to future updates.

Pretty useless

I’m not sure where this app gets its calculations from. I downloaded it more out of curiosity because I’m an advanced athlete and I know exactly how I’m feeling and when I need to take it easy and when I can push it. I always do think that HRV is a fairly decent approximation of how ready you are to train. So I thought hey let’s see if this actually works.

Bad news: it doesn’t. You would think it would be pretty easy app to design. Just look at your average HRV and see if you are below or above. Then give yourself a score. You can see average HRV for any period in the Apple health app. You can also see your latest HRV value. So just do the math and voila. But this app really doesn’t seem to capable of making that calculation, instead relying on smoothing or something. If you play with the two settings you can get the app to say completely different things, which is frankly laughable.

I get this is basically a beta, so I’ll give them a chance to improve but really how difficult is it to do that very simple calculation?
