About TrainOrRest
TrainOrRest answers one question before you lace up. Should you train, go easy, or rest today? The call sits at the top of the calendar. It comes from your Garmin data in Apple Health and a race plan that only changes when you apply it. Who it is for Serious recreational runners on iPhone, with a Garmin and a race on the calendar. If you want streaks and a feed, this is the wrong app. Today's call Open the app around the decision, not around a dashboard. Train, go easy, rest, or the workout already planned. The reasons are your numbers. HRV, sleep, resting heart rate, recent load. A stale sync is labeled stale. Missing data stays missing. The app does not invent a score to keep you moving. The plan Pick a 5K, 10K, half marathon, or marathon. Set the days you can run. The engine writes a deterministic schedule. Readiness can downshift a week through named rules you can inspect. The coach can propose an edit in chat. A local validator has to pass first. Nothing lands on the calendar until you tap Apply. You can revert. Coach Ask why today's session looks the way it does. Ask what to change after a rough night. Claude explains and proposes. It does not own the plan. Sync Garmin Connect through Apple Health. Optional Google Calendar so the week shows up where you already look. What it will not do Cheer you into a run you should skip. Treat a 14-hour-old sync as a fresh read. Let an AI edit rewrite the week without your tap.
What’s new
Version 1.0.1 · Updated October 1, 2026
Coach sign-in and a calmer setup. • Sign in to Coach with ChatGPT or Grok, or keep using your own API key. • Optional setup now lives in one hub. Connect Health, your calendar, and intervals.icu when you want to, not during first launch. • Connect intervals.icu without pasting an API key. • After a finished run, Coach can review and adjust next week's plan. • The month calendar shows your training phase, weekly planned versus completed distance, and the weather on Today's Call. • Link and unlink runs from a workout, with automatic matching when a session moves. • Shoe rotation assigns gear for you and reminds you when a pair is worn out. • Coach chat answers plan lookups, explains training terms in a tappable glossary, and stages every plan edit for your confirmation before anything changes. • Many fixes across plan editing, Health permissions, weather fallbacks, and localization.
