As of November 2026, Owaves: My BodyClock and Apple’s Calendar app are both free on iPhone, iPad and Apple Watch. Apple Calendar keeps events, invitations and shared iCloud calendars in List, Day, Week or Month views. Owaves plans all 24 hours as one circle in 8 activity categories around your body clock, and can show Apple Calendar events synced to iOS.

Key takeaways

  • Both are free; BodyClock Plus, the Owaves subscription, costs $12.99 a month or $99.99 a year (US), with a free trial [1][6].
  • Apple Calendar syncs through iCloud to iPhone, iPad, Mac, Windows and iCloud.com [6][10].
  • Owaves plans a whole day, sleep included, on My BodyClock, and a 1-minute quiz predicts your Body Clock Type [1][4].
  • You can use both: Owaves can show your Apple Calendar events [5].

What is the main difference between Owaves and Apple Calendar?

Apple Calendar shows when you are booked and with whom; Owaves shows how all 24 hours of your day fit your body clock.

Apple’s listing describes one view of events from all your calendar accounts, alongside reminders, holidays and birthdays, plus invitations and shared calendars [6]. The Owaves listing describes a 360° circular view of your 24 hours, aimed at time blindness [1], with 8 color-coded activity categories: Move, Eat, Relax, Love, Play, Work, Flow and Sleep (Owaves FAQ). See what the colors in Owaves mean.

What does Owaves do that Apple Calendar does not?

Owaves puts sleep, meals, movement and rest on the plan alongside work. The free app covers My BodyClock, My Goals and My Moai, and connects to Apple Health to compare planned and actual activity [1].

The Body Clock Quiz takes about a minute and predicts your chronotype (your Body Clock Type) with a sample Day Plan (Owaves FAQ). Since version 8.0, new users start with a short chat that reads their body clock, shapes an ideal day and sets a first seasonal goal [1]. BodyClock Plus adds Windows: daily BodyClock AI recommendations for Deep Sleep, Deep Work, Peak Fitness and Eating Windows, drawn from your chronotype, tracked activities and Apple Health data (BodyClock AI announcement, October 2025). See how to use Windows in Owaves.

What does Apple Calendar do that Owaves does not?

Apple Calendar is built for scheduling with other people. With iCloud, a change on one device appears on all of them, including a Windows PC and iCloud.com [10][13].

Events carry a location or FaceTime link, invitees, attachments and alerts; with an address, Calendar uses Apple Maps traffic and transit to tell you when to leave [7]. With Apple Intelligence (iPhone 15 Pro, iPhone 15 Pro Max or an iPhone 16 model or later), you can type a plain description of an event and get suggested details; Siri can also suggest events from Mail, Messages and Safari, such as flight bookings [7].

Can you use Owaves and Apple Calendar together?

Yes. Owaves can show calendars synced to iOS: allow Owaves to access Calendars in iOS Settings, then pick calendars under Settings → Synced Calendars in Owaves (Owaves FAQ).

Apple Calendar keeps the meetings and family plans, which can include Google and Exchange accounts [6]; My BodyClock holds the rest of the day: sleep, a walk in daylight, steady meals and a wind-down. See also Owaves vs Google Calendar.

Who is each app for?

Owaves: My BodyClock suits you if you:
– want sleep, meals and movement on the same page as work or class;
– want to plan around your Body Clock Type, or time workouts and meals with Windows;
– use an Apple Watch and Apple Health and want planned vs actual activity (how to connect Owaves to Apple Health).

Apple Calendar suits you if you:
– send and answer invitations, or share calendars with family and colleagues;
– want reminders, holidays and birthdays next to your events;
– need your calendar on a Mac, a Windows PC or the web too.
