The best app blocker.

Ranked honestly for 2026. And one honest warning: the best way to beat a habit is usually not a blocker at all.

App blockers feel decisive: build a wall, problem solved. In practice most people turn them off within a week, or tap straight through. They treat the symptom, not the craving. Here is the honest ranking, strict blockers included, plus the smarter option at the top.

01

Anása

Catches & replaces · Free

Instead of a wall, Anása catches the moment a feed opens, asks for a breath, and hands you a better thing to do, then learns what works for you. Gentle friction you will not rage-quit. Free, private, on your phone.

Best for: anyone whose blockers keep getting switched off.

02

Freedom

Cross-device wall

Blocks apps and sites across phone and computer on a schedule. Strong and strict. Subscription, and pure willpower.

03

Opal

Polished sessions

Clean focus sessions and stats. Good for set hours. Paid, no replacement.

04

ScreenZen

Free friction

Free delays and prompts. A light speed bump rather than a hard block.

05

Cold Turkey

Strict, desktop-first

Near-unbreakable blocks, mostly for computers. Powerful, blunt, no mobile habit replacement.

Why a blocker alone rarely lasts

A wall cannot beat a craving. When the urge hits, you turn the blocker off, switch devices, or wait it out. And blocking does nothing about the feeling that sent you there. The fix is to catch the moment gently and give the urge somewhere better to go. That is the one thing a pure blocker never does, and the one thing Anása is built around.

Better than a wall.

Free on iPhone and Android. Everything stays on your phone.
