Apple

The ability to upload a GPX file for navigation during a workout. I know you can use WorkOutdoors but I find it clunky and would love the have the option to do this in the workout app.

It’s crazy that this hasn’t been mentioned once in this entire thread, but maybe that’s because people don’t want it and that’s why we don’t have it 🤷‍♂️

Ability to connect with any phone (including Android) 😄

A camera.

Notifications that work.

Battery life

Control iPad media playback

i already can control my Apple TV and my iPhone media playback. Why not my iPad?

Longer battery life!!!!!! At least 3 days!

Naps please 🙏🏻

I just want my manual “turn the crown” for night mode back on my ultra. The automatic selection is annoying me to no end, and I actually use night mode.

1. I’d like to go back to just Recent and Favorite timers, instead of Revents and an ever growing list of every random timer I’ve ever set on watchOS 10
2. More customizable Watch faces and options for analog hands or digital display where applicable. Not necessarily third party faces, but say I want to take Infograph and replace the analog hands with digital time on one of the sub dial, or I want to replace the time display on a Modular variant with digital time and an additional complication.
3. Non-invasive Glucose Approximation

I have a 3 so I’m not sure if this is a feature by now, but I’d like to be able to see my phone’s battery % from the watch

Automation/shortcut options referring to the WATCH battery specifically (there's only for the iPhone!). I'd love to create an automation that would give me a notification whenever my watch battery is low!

For the notification to go away if I’ve already seen it even if it’s just been 5 seconds.

Show Reminders Flagged items in the wide Reminders complication, rather than only allowing the Today view. If you use Reminders, then the natural path is to flag stuff each day, not to assign specific times for each item. You can change the iPhone widgets this way, it's maddening that you can do it on the watch, too.

The ability to sell them to Android users.

1. Auto detect sleep rather than using sleep schedule
2. With the above working, set “sleep duration based alarms”. For example, I want it to wake me up 30 mins after I fell asleep during the day (nap)

Custom Watch Faces

Better sync between phone and watch. I want timers to sync between phone and watch regardless from which device they are started. Also I want two customize individually which alarm will only vibrate on watch, play sound on watch / phone. Also the synchronisation for Podcasts and for audible books is ridiculous. If I start playing on watch and want to continue later on phone it doesn't pick up seamlessly. I think this is a shame for the company around "it's just works". It's a great smartwatch, but doesn't hold up to Steve Jobs' standards imo
