New charts and data are now available! Single in-app purchase provides baseline fitness chart of HRV and RHR, historic RTT data; and a widget to use on your home screen.

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.

Good... in theory?

Edit 2: changing to 5 stars because Ian on the dev team went above and beyond to help me out with the app. Couldn't figure it out in the long run but appreciate the customer support and will keep the app to see if/how it improves over time.

Edit: ended up just deleting. No response from team with an app that's got just over 200 reviews. The app might as well be just pulling arbitrary numbers. I'm fully rested and ready to train, and it's telling me I'm at a 3 and should rest. Better off just seeing how you feel than try and decipher what this app is trying to tell you. Not sure what the 5 star reviews are about.

Not sure how to read this. I workout heavy weights for over an hour. Sleep a decent 7 hours. Run 4 miles in 100 degree weather and it still says "10 - peak performance!" How about maybe 5? And this is with intensity adjusted to -10. Like, what? Not to mention it has said "no hrv reading use breathe app" every day even though i have hrv readings via my health app AND have done the breathe app twice each day. So what exactly does your app DO? I know what it's SUPPOSED to do. Luckily it's free and easy to delete. Anyone have suggestions for an app that does what this says it does but actually works? Im willing to pay. Just want something to help gauge my recovery and "readiness" to train.

Sorry we have not responded earlier and I’d like to understand why the app is reporting bad data for you. If you would like to give it another go please email me at and we can investigate

Kind regards

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.

Love the app and can’t wait for more features!

Hello, I just had to comment because this app is exactly what I have been looking for and does a great job at it too. In essence, this app tracks your HRV over a period of time, including during the evening which is the best time to measure when viewing how “recovered” you are and ready to take on more strain. I compare this to the Whoop strap recovery system, and it’s pretty spot on regarding how recovered my body is compared to Whoop. I know Whoop takes HRV, RHR, and sleep into account for their recovery score, and I think this only takes into account HRV. I know the others might be duplicative and I’m not sure if this takes into account RHR. Keep it up though, look forward to more features as you roll them out!
