Requires you to start an expensive trial to even use the lite version

During app setup there is no clear way to skip the trial for the extremely expensive subscription. Horrible and bad UX with the goal of hoping you forget about the subscription.

Garmin Support please

I have been using premium for years, and would much appreciate an update. It’s so much easier to fall asleep without worrying about opening a screen. Any word of this would be nice.

Scam

You have to start a trial to use the app, it is not a free app.
