LoadSense

Daily scores, trends over 7 and 28 days, a journal, a workout simulator, training load, an Apple Watch companion and widgets are free. One preview of the seven-day load projection is included on the device when enough data exists. That preview does not start a subscription.

Pro compares the week with and without a planned workout, compares days for that workout, and answers from the data stored on the device, with dates and limits. Projections use stated assumptions. They do not predict recovery.

LoadSense is a wellness tool, not a medical device. It needs iOS 18 or later. The Watch app needs watchOS 11 or later.
