TaskLock vs ScreenZen

In short: choose TaskLock if the lock should end only when the task is done and you want your to-do list in the same app. Choose ScreenZen if you want a completely free app that adds waits and daily open limits, including on Android. Both are built for people who want to keep themselves honest rather than for parents.

  • You use an Apple Watch.
  • You want no account and full offline use.

What they have in common

Both are free to use, both can block websites as well as apps, and both share the idea that an app should be earned rather than opened on reflex: ScreenZen with a short activity, TaskLock with a finished task.

Common questions

Is ScreenZen really free?

Yes. ScreenZen says it is completely free and supported by optional donations, offered as tips in the app. TaskLock is free to download with limits on how many tasks, habits and events you can create; Premium removes them.

Can ScreenZen make me do something before opening an app?

Yes. ScreenZen can require a short activity such as breathing, journaling or learning before an app opens. TaskLock takes a different approach: the lock is tied to a real to-do item, and the app stays locked until that item is checked off.

Which is stricter?

TaskLock, for the apps you lock. A TaskLock lock has no wait-and-open path: the app stays shielded until the task is done or the event ends, and early unlocks go through a countdown and a daily limit. ScreenZen can be strict too through its strict block and settings lock, but its default model is to delay opens rather than prevent them.
