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.

Train with clarity, not guesswork. Simple Insights uses Apple Health and Apple Intelligence to turn your health and workout data into clear coaching answers for recovery, training, movement, and performance — processed on device, no cloud required. Start with a 7-day free trial with full access. No account. No cloud processing. No data selling. Ever. NEW: Coach-Ready Workout Details Open any workout and read a plain sentence about it — “A hard 45-minute ride — one of your bigger workloads in the last 14 days” — before a single number. Then the figures a coach would ask for: • Training Load (TSS) and Intensity Factor, on every activity type • Zone 4+ efforts, longest effort, and dominant zone • Elapsed, active, and paused time • Heart rate drift, time to peak, average as a percentage of max • A comparison against your own recent sessions, not a population average Tap any figure for a plain-language explainer. Share the session as an image, or export the heart rate data as a spreadsheet. The last 7 days are free; subscribers get full history, sharing, and export. Ask AI (Powered by Apple Intelligence) Ask natural-language questions about your health and performance, answered from your own Apple Health trends, on device. • “How much did I train this week vs last week?” • “Show my HRV trend over the last 30 days.” • “Tell me about Morning Briefing.” • “Is my data private in Simple Insights?” Subscribers get unlimited prompts. Free mode includes 2 per day. Ask AI requires an Apple Intelligence compatible iPhone. Heart Rate Data Export Your workout data belongs to you. Export any workout’s heart rate readings to a CSV spreadsheet for Numbers, Excel, or Google Sheets — every reading in order, with elapsed time, zone, and percentage of max. Built on device, nothing uploaded. Morning Briefing Start each day with a proactive recommendation — Push, Steady, or Recover — plus a confidence score and the key drivers behind it. Tap through for how each number was calculated. Trend Anomaly Alerts Simple Insights watches your trends for you. When resting heart rate spikes, HRV drops, sleep declines, or activity falls off, you get a clear alert before you feel the impact. Workout streaks and new personal bests are flagged too. Every alert says what changed, why it matters, and what to do — then clears itself when the trend recovers. Weekly Intelligence Report A weekly report that answers one question: “Am I improving?” • Training, Recovery, Movement, and Sleep sections • Confidence-aware interpretation • Driver lines and practical next actions • Shareable PDF export for coach check-ins Built for Apple Health users Works with what you already track — Apple Watch, compatible heart rate monitors and exercise machines, and other Apple Health sources. No manual syncing. Recovery Intelligence • HRV trends • Resting heart rate patterns • High and low heart rate monitoring • Recovery behavior over time Training Intelligence • Per-session Training Load (TSS) and Intensity Factor • Heart rate zone distribution, Zone 4+ efforts, and drift • Weekly and monthly training comparisons • Workout trend summaries Movement Intelligence • Steps and movement trends • Active calorie patterns • Weekly and monthly consistency signals Intelligent Dashboards • My Dashboard and Coach Dashboard • Modular tile layouts you can reorder and personalize Privacy First by Design • On-device processing • Your data is exportable as a spreadsheet • No logins, no accounts • No ads • No cloud processing • No tracking Exports, dashboards, weekly reports, and detailed alerts are subscriber features. Free mode remains fully usable. Subscription Information Auto-renewing monthly and annual subscriptions. Pricing varies by region. Renews unless canceled in App Store settings.

Verdict

The call

The clearest difference is update cadence: Simple Insights at every 2 days against Training Today's every 6 weeks. Simple Insights also leads on rating (4.8 vs 4.6). Training Today's advantage is ratings volume (2.6K vs 5) and iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.
