Is a white noise machine better than an app?
Dedicated machines like the LectroFan don't require a phone, have no notifications or ads, and produce consistent analog-quality sound. Apps like Softly offer more variety and are free, but require a device. Many people use both — the machine at home and an app while traveling.
LectroFan Evo vs LectroFan Classic — what's the difference?
The Evo adds 2 ocean surf sounds, a headphone jack, and USB-C charging. The Classic has 20 sounds (no ocean) and micro-USB. For most people, the Evo's extras are worth the small price difference.
