Comparison
RestOrTrain vs Runna
Ask RestOrTrain why a session felt hard or how to pace a race. It answers from your runs, rides, swims, sleep and HRV, and gives the reasoning.
RestOrTrain plans running, cycling and swimming together, or a triathlon. Runna builds running plans, and its triathlon plans "focus on the running component only".

How each app builds a plan
Runna's policy summary says its plans are "designed by experienced coaches using established training principles, not AI". Runna sets your pace targets from a current 5K, 10K or half marathon time.
RestOrTrain plans around a goal in your own words: "Run the Berlin Marathon under 3 hours". It builds each workout for you and for that day.
What each app reads and keeps
RestOrTrain keeps what lasts from your chats, from an injury to your equipment, in a Memory list on the Profile tab. You can read it, add to it and remove entries, and later answers and plans use it. The notes you write on a run inform its answers too, outside that list.
Your sleep, HRV and resting heart rate come in from Garmin, COROS, WHOOP, Intervals.icu or Apple Health on iPhone. Runna's pages say your heart rate "will not influence your training plan" and its pace suggestions "can't yet account for" poor sleep.
Frequently asked questions
Does Runna use AI?
Runna uses AI for a briefing before a run and for feedback after a workout. It says: "Workout Insight feedback will not impact your training plan!" No Runna page describes a chat where AI answers a runner's own questions about training. RestOrTrain's AI answers them from numbers calculated with fixed formulas, such as training load.
What does Runna have that RestOrTrain does not?
Runna has audio cues, phone recording, treadmill control and its own Apple Watch app. For runs, RestOrTrain has none of them: your watch records the run and guides each step, and the indoor player is for cycling. RestOrTrain sends planned runs to Garmin and COROS watches, and from an iPhone to the Apple Watch. It sends none directly to Suunto, Amazfit, Polar, Fitbit or Wear OS watches, and Runna also syncs to Suunto and Amazfit.
Can I change or delete a planned workout?
Tell RestOrTrain "move my long run to Saturday" and it makes the change in its reply. A swipe deletes a planned workout. Runna's pages say you "can't delete a single planned workout right now".
