Sleep well to a deep, boring voice — an alternative to sleep stories and white noise. This ASMR sleep aid is for relaxation, insomnia relief and racing minds that need to fall asleep.

Tonight, step away from the regional chaos of imperial measurements to find solace in the global uniformity of ISO 261. This is the International Organization for Standardization's definitive blueprint for the metric screw threads that hold the modern world together. From the microscopic screws in a Swiss timepiece to the massive bolts securing a bridge in Vancouver, we explore a world governed by pitch, lead, and tolerance. We are auditing the "M series", a sequence of numerical constants where the diameter of a fastener is never a matter of opinion, but a mathematical certainty. It is a study in friction, torque, and the quiet, industrial harmony of the SI system. It's a landscape where every millimeter is accounted for and every rotation serves a singular, unyielding purpose.

Deeply Unimportant is a sleep ASMR sleeping aid for minds that need structure to drift off. An alternative to CBT therapy, it employs a form of what sleep scientists call cognitive shuffling that can overcome mind racing thoughts at night. No whispers or fairy tales; just an ordered, structured, boring voice of a real life former newscaster reading material that doesn't matter.
