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.

PBSplits
Read full descriptionHide full description
PBSplits is a free app that finds your fastest split at every standard distance across your run history. Most personal-best tools only know your finish times. If you've never raced a 5K, they think you've never done one. PBSplits looks inside each run and finds the fastest continuous window for every distance on the ladder, so the best 5K you ever ran shows up even if it was the middle 5K of a 12 K training jog. Three tabs, and it opens on the first. Runs is every run in your Health data — pull to refresh, tap any one to open it, even the ones that never hit a standard distance. Trends plots a distance over time, as pace or as finish time, with a year-over-year view to lay this season against the last. Bests is the record book: the ladder from 400 m to 100 K, grouped Short / Road / Ultra. Tap any effort and you get the whole run — the route on a map with the record-winning segment highlighted, a mile-by-mile splits table, and pace and elevation charts. Tap a split and its window lights up on the map and across the charts, so you can see exactly where you found the time. Season and all-time crowns mark the efforts that took a podium. Great for: • Runners who want PBs from training, not just races • Tracking progress over a season or a year • Finding the fastest you've ever covered a 5 K, 10 K, half, or marathon • Comparing efforts across short, road, and ultra distances • Anyone whose watch knows more than they do What you get: • Best-effort engine that finds your fastest continuous split at every distance, not whole-run averages • Full distance ladder from 400 m to 100 K, grouped Short / Road / Ultra • Every run, browsable: pull to refresh, and open runs that never hit a standard distance • Trend charts, progression and year-over-year, by pace or by time, pinch to zoom either axis • Mile-by-mile splits: tap a split to highlight its window on the map and the charts • Map view per effort, with the winning segment highlighted on the route • Season and all-time crowns on podium efforts • Share cards for a new PB, a podium, or your whole record book • Pick your pace units: min/km or min/mi • PBSplits reads your workouts from Apple Health and never writes to it • Your run data stays on your device Free to download — no subscription, no account.
