No. Cold Turkey is Windows and macOS only, and it isn’t an oversight — it’s a hard limit in how iOS works. Here is what that limit actually is, and what the strictest possible iPhone blocker can and can’t do inside it.
Cold Turkey’s strictness on desktop comes from things a desktop OS lets a program do: run a background service that survives the UI being killed, sit between the browser and the network, and refuse to be uninstalled while a block is running.
iOS permits none of that to third-party apps. There are no long-running background daemons you can install, no way to intercept another app’s traffic without a VPN profile the user can disable in two taps, and no mechanism to prevent your own app from being deleted. An app that tried Cold Turkey’s desktop approach on iOS would be rejected from the App Store, and wouldn’t work if it weren’t.
Any iPhone “blocker” claiming desktop-grade unbreakability is either using Apple’s Screen Time APIs like everyone else, or asking you to install a device-management profile that hands it far more control than a focus app should have.
Apple’s Family Controls and Managed Settings APIs are the sanctioned path. They let an app shield your chosen apps behind a system-level screen that the app itself cannot be talked out of. The strictness comes from the design decisions layered on top:
Sleep Well’s Cold Block takes a duration up front — 1, 7, 30, 57, or 90 days — and offers no in-app way to shorten it. Most blockers include a stop control, and that control is the one everybody uses at 1am.
A multi-day block lives in its own Screen Time store, separate from the nightly bedtime schedule, so a 7am wake-up releases bedtime without touching a 30-day commitment.
Shields apply to apps you explicitly choose. Leave Phone and Camera unselected and they work normally. Emergency SOS is controlled by iOS and sits outside any third-party app.

On a phone you authorized yourself, you can withdraw Screen Time permission. No third-party app can prevent that — including this one. The honest mitigation is to set it up through Family Sharing with someone else as the guardian, which puts the authorization behind a passcode you don’t have.
That’s the real ceiling on iPhone blocking, and it applies to every app in the category equally. Anyone telling you otherwise is selling something.
The Mac app is available now. The iPhone and iPad app — Cold Block, the nightly shield, and a bounded release that syncs from the physical key on your Mac — is in development. One email when it ships, and nothing else.
No newsletter, no drip sequence, no sharing.
