Dodow
Dodow Plus Sleep Aid
Best for: Busy-headed sleepers who want a wordless, screen-free breathing cue.
Trade-off: It is a light in a dark room, and it teaches a technique you may soon not need it for.
Head-to-head
Two wind-down cues at opposite ends of complexity: a disc with a light and three AAA batteries, or a wearable with an app, a charger and a membership.
The short answer
Buy the Dodow if you want the simplest possible cue for a racing mind: a light on the ceiling that paces slow breathing — a technique with reasonable evidence — for eight minutes, then switches off, for a low one-time cost. Buy the Apollo Neuro only as a deliberate experiment: you respond to touch, you want it automated and worn, and you accept charging, an app, a membership after year one, and evidence that is mostly the company's. Start with the Dodow.

When each one wins
The SleepOriginal verdict
The Dodow does one evidence-based thing cheaply and asks nothing. The Apollo does a more speculative thing expensively and asks for daily charging. Unless you know touch is your cue, the light is the sensible first try.
Questions
The projection is dim and lasts 8 or 20 minutes. Most partners do not notice; a light-sensitive one might, in which case the Apollo's silent vibration or a weighted blanket is the quieter cue.
