Cold Turkey doesn't
run on iPhone. Fella does.

Cold Turkey has a well-earned reputation as one of the strictest blockers available, locked schedules, a "Frozen Turkey" mode that can't be undone until it expires, blocks that survive a computer restart. It's a genuinely serious tool for people who've tried softer app limits and needed something that doesn't bend. The catch, for a lot of people searching for it, is that it's built for Windows and Mac. There's no official Cold Turkey app for iPhone.

That leaves a real gap for anyone whose actual problem lives on their phone, not their laptop. Fella isn't a port of Cold Turkey, it's a separate iOS app built specifically around Apple's Screen Time framework, but it shares the same basic philosophy: the block is the default, and getting around it isn't a single tap.

It actually runs on the device causing the problem. For most people struggling with distracting apps, that device is an iPhone, not a desktop. Fella works where the compulsive checking actually happens.

Same strict-by-default instinct, built for Apple's platform. Fella uses Apple's Screen Time and Family Controls frameworks to keep selected apps locked, with one 5-minute emergency unlock a day that closes itself automatically, no bypass toggle, no "just this once" setting.

One rule instead of a schedule to configure. Cold Turkey's strength on desktop is its depth, custom schedules, frozen modes, block lists per project. Fella deliberately trades that depth for simplicity: pick your apps once, and the block just holds.
