Cold Turkey Blocker is a desktop blocker for Windows and Mac. The Blocker licence is a $39 one-time purchase. Frozen Turkey (the kiosk-style lock) and other extras sit on top. Mobile is not the product. Price checked 21 September 2026 against vendor and 2026 roundups.
Phone Instagram will still win if you only blocked the laptop. Pair it with Opal or Freedom on iOS, or leave the phone in another room.

Mean in a useful way on a PC. Incomplete as a life system. Buy it for the exam laptop, not as your only blocker.

Hard blocking across iPhone, Android, and Mac.
A breath and a delay instead of a hard block.
