Questions
What data does Exoplan read?
Sleep, heart rate and activity from Apple Health. With an Apple Watch, Exoplan learns from your own data after a short calibration period. Without one, it estimates your rhythm from your chronotype.
Do I need an Apple Watch?
No. Exoplan works with the sleep and heart-rate data in Apple Health, wherever it comes from. Without a tracker, it estimates your rhythm from your chronotype, which you set during onboarding. An Apple Watch gives it the most data to learn from.
Is there an Apple Watch app?
No. Exoplan runs on iPhone and reads your Apple Watch data through Apple Health.
Is my energy measured?
No, it’s estimated. Exoplan looks at when you slept and how your heart rate and activity changed over recent weeks, then predicts when your energy usually rises and dips. It’s a planning aid, not medical advice. The research note Exoplan energy algorithm explains each step.
Which calendars does it work with?
Apple Calendar, including iCloud, Exchange and every other account on your iPhone, plus Google Calendar. You can connect more than one Google account.
Which iPhones are supported?
Any iPhone with iOS 18 or later. The app is in English.
Is Exoplan free?
Exoplan is free to download. Exoplan Pro unlocks the AI planner and voice input for $9.99 a month or $59.99 a year (US prices), with a free trial.
What happens to my data?
Health data is read on your iPhone. To build your energy model, recent heart-rate, activity and sleep data goes to Exoplan’s server, which doesn’t store it. Planner requests go to OpenAI. Exoplan doesn’t sell your data. Details are in the privacy policy.
