Author: Zone2Ai

Zone 2 AI (Zone2AI) is a subscription app. The Garmin watch app is free, and it works with the Zone2AI phone app for iPhone or Android, which requires a subscription after a short setup.

Plans: weekly, yearly, or a one-time lifetime purchase (pay once, keep forever). You can see the exact price for your country in the phone app before paying anything.

What the watch app does: real-time Zone 2 heart-rate tracking on your Garmin, with your session synced to the phone app for scoring and coaching. Your workout appears in the Zone2AI phone app once Garmin Connect syncs, usually within a few minutes.
