What is the cost of the Aichom app?

It is completely free - find and download it on the Apple App Store (US, CA, UK regions).

When would I get a notification, if a person with a smartwatch & Aichom app, is changing location?

Aichom app refreshes the location of a smartwatch every 90s.

If I have my own smartwatch paired with my phone, how should I pair the smartwatch of a person with dementia?

1. Sign-up and set-up the Aichom app on the patient's phone/smartwatch;
2. Use the patient's details to log-in in the Aichom app on the caregiver's phone.
