I went from a series 0 to a 4 earlier this year. Voiceover works beautifully on it. I use mine predominantly for the workout feature.

I am blind and have been lucky enough to own all the watches.

Series 4 is when VOiceOver really became a smooth experience. VoiceOver is highly reactive with minimal lag, enjoy using the watch. Where as on previous version the voiceover delay would often become frustrating.

In terms of what i use it for. Telling the time, workout tracking, remote control for Apple TV and Sonos, texting people, controlling HomeKit devices using Siri and other general Siri bits.

Hello! I’ll answer on behalf of my husband, who is visually impaired/blind. He upgraded to a Series 4 from a Series 2 earlier this year, and he loves it. He’s very active, and mainly uses his watch for workout purposes. He really appreciated the update to Siri so it now actually speaks on the Series 4 watches instead of before where the text would appear on the screen. VoiceOver works very well on the watch overall, and with the Workout app, which is probably his most used app on the watch. He also uses it to read text messages and answer calls when his phone isn’t nearby. If you have any other questions, don’t hesitate to DM me and we’ll be happy to answer them!
