What devices does Milo require?
To get the best performance and access all features, Milo needs the following:
Apple Watch: watchOS 10 or later
Supports Apple Watch Series 4, Apple Watch SE (1st gen), and all newer models, including Ultra.
iPhone: iOS 17 or later
Any iPhone that runs iOS 17 is supported. You can check this in Settings > General > About.
Milo uses Apple’s newest mapping, HealthKit, and interface technologies, so modern operating systems are required.
