Amazon discontinues Halo devices and services.

Amazon has decided to shut down its health-focused Halo division and discontinue all Halo hardware due to significant headwinds, including an increasingly crowded segment and an uncertain economic environment. The company plans to lay off portions of the Halo team and fully refund any customers who bought a Halo device or accessory band in the last 12 months. All unused prepaid Halo subscription fees will be refunded, and users will no longer be charged. The devices will stop working on August 1st, and all remaining data will be deleted.
