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. 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. * We use Heart Rate Variability (HRV), Workout detection and our own algorithm to determine your RTT score. * 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. The following are available in the subscription version: * Siri support - ask, "Hey Siri, what's my Training Today score?" or "Hey Siri, what's my Training Today RTT?" to see your score and current weekly chart * Siri shortcuts - get your current Training Today score as input for automation you can create in Apple Shortcuts. * Apple Watch notifications when your RTT drops by a configured amount compared to your 4-day average. * View your RTT chart on your iPhone as well as your Apple Watch * View your complete baseline HRV and RHR (Resting Heart Rate) data in the iPhone app and scroll through Years, Months and the related weekly RTT charts. * Fine-tune your RTT score using Smoothing and Intensity Settings on your iPhone * Add widgets to your iPhone home screens and lock screens showing your current RTT score and chart. * Apple Watch Smart Stack Widget * Compare your Resting Heart Rate data with your RTT and HRV scores. * Notifications on Apple Watch when your RTT changes over a configured value compared to your 4-day average. * More features with each release More info at https://TrainingTodayApp.com For best performance, wear your Apple Watch as much as possible and overnight if you can.

MyCaffeine helps you track your daily caffeine intake and understand how it affects your body — from your morning coffee to your last drink before bed. Log a drink in seconds, see exactly how much caffeine is in your system right now, and get a clear picture of how it builds up and fades throughout the day. Caffeine Tracking - See the current caffeine level in your body, updated in real time. - A live prediction graph shows your caffeine rising and falling across 24 hours, centred on now. - Caffeine now absorbs gradually rather than spiking instantly, so the curve better matches how you actually feel. - Forecast how much caffeine will still be in your system at bedtime. - A heads-up before you log a drink that would push you past your daily or bedtime limit. Water Tracking - Track your hydration alongside your caffeine, with a daily goal and a rolling 24-hour graph. - A hydration status label, from Dehydrated to Well Hydrated. - Water from every drink you log counts automatically. Apple Watch - Log drinks and water straight from your wrist. - Check your caffeine, hydration and daily total at a glance. - Complications for your watch face, kept in sync with your iPhone. Health Analysis - See how your caffeine lines up with your sleep, heart rate and activity, using data already in Apple Health. - Plain-language findings explain what your data actually shows. Trends & History - Track your intake, weekly patterns and bedtime caffeine levels over time. - Findings on every chart explain what you're looking at, in plain language. - Brand Ranking shows which brands you drink most, and what they add up to. - A calendar history with colour-coded daily intake at a glance. - Edit or delete any drink you've logged, from Today or History. Branded Drinks - Browse a growing catalogue from Coca-Cola, Starbucks, Red Bull and more — with serving sizes, nutrition and ingredients built in. - A redesigned Drinks tab, with search that ranks the closest matches first. - Your recent drinks are one tap away, remembering the serving size you last used. Custom Beverages - Create your own drinks based on caffeine quantity or concentration. - Custom drinks are saved under their own brand. - Decimal precision for more accurate tracking. Made For You - A metabolic calculator personalises your caffeine half-life and daily limits, instead of guessing. Widgets - Home Screen widgets showing your current level, drinks today, predicted bedtime level, and a 24-hour graph. - Lock Screen widgets to check your caffeine at a glance. - Water widgets for your Home Screen, Lock Screen and Apple Watch. - Quick Add shortcuts you choose, so your usuals are always one tap away.

Verdict

The call

The clearest difference is rating: Training Today at 4.6 against MyCaffeine's 3.6. Training Today also leads on ads (none vs shown) and ratings volume (2.6K vs 5). MyCaffeine's advantage is review sentiment (75% vs 53%) and update cadence (every 9 days vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Training Today sells 4 in-app purchases, starting at $2.95 per month and MyCaffeine sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Training Today holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Training Today has 2.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 53% of Training Today's written reviews are positive against 75% of MyCaffeine's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Training Today ships an update every 6 weeks, MyCaffeine every 9 days. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
