Kaptain organizes your training around your real life: your workouts automatically find their place in your calendar, without ever clashing with an appointment. Tell Kaptain your sports, how many workouts you want each week and your daily schedule, and it builds your week: each workout lands in your free time, around your work, your rest days and your sleep. WHAT KAPTAIN DOES • Schedules your workouts automatically, around your real calendar • Brings your day together on one screen: workouts, appointments, work, sleep • Spots workouts that clash with an appointment and replans your week in one tap • Recognizes the workouts recorded in Apple Health and checks off your sessions for you • Breaks down every workout: heart rate, zones, power, cadence, route and weather • Shows the weather for your outdoor workouts • Reminds you of your workouts at the right time and sends a recap every morning • Apple Watch: your day on your wrist, complete or shift a workout, and your next workout as a complication • "Next workout" Home Screen widget KAPTAIN PRO • Koach, your AI coach — tell it "move my workout to tomorrow" or "I'm wiped out this week": it knows your calendar, your sleep and how you're feeling today, and reorganizes your workouts. You always have the final say. • Alternate app icons Subscription • 7-day free trial, then a yearly or monthly subscription The free trial is offered once, on the annual plan, to eligible accounts.

Koach — credits The Pro subscription includes a set number of Koach messages per day. Beyond that, additional credits (in-app purchase, 1 credit = 1 message) let you keep the conversation going. Kaptain uses your location only to show the weather for your workouts. Your Apple Health data is used only to organize your workouts, never for advertising.
