Ambient's Dreamie offers many of the conveniences of a smartphone-connected device — highly customizable alarm schedules, a library of soundscapes and noise masks, Bluetooth so you can connect earbuds and podcasts (soon). But it is phone-free every step of the way, with all controls and features built-in so you don't end up getting sucked into a doomscroll while you're trying to wind down. It also has a light ring for ambient lighting modes and sunrise wakeups.
