Adaptive Sound Technologies
LectroFan EVO
A plain plug-in sound machine with 22 fan, white/pink/brown noise and ocean sounds and no app; the catch is it needs an outlet, it does not run on a battery.
- Buy it if
- Anyone sleeping in the daytime on a noisy street who wants steady sound with zero setup.
- Skip it if
- You want something that travels on battery power.

Alternatives worth comparing
Elgato Key Light (Air/Mini)
The streamer-desk lighting standard; app-controlled, but you're paying a brand premium over generic panels.
NewO2COOL Rechargeable USB Battery Clip Fan with Gooseneck (FC35B03)
Clips onto a bunk rail or desk, bends where you point it and runs over six hours on a charge; the blades are only 4 inches, so it cools one sleeper, not the room.
