Comparison guide

one sec Alternative: Weeklane Task Lock vs one sec

one sec slows you down with a short pause before a distracting app opens. Weeklane Task Lock keeps chosen apps locked until today's to-do list is done. Different ideas, both useful. Here is how they compare.

Published Updated

Short answer: choose one sec if you want gentle friction, such as a breathing pause before Instagram opens, that still lets you decide, across iPhone, iPad, Mac, Android and browsers. Choose Weeklane Task Lock if pauses are too easy to tap through and you want the apps to stay closed until today's tasks are actually done.

one sec is a well-known intervention app with research behind it: its developer reports studies run with the Max Planck Institute and Heidelberg University. Weeklane is a minimalist weekly planner, and Task Lock (since Weeklane 2.5) adds a task-based lock to it. They solve the same problem from opposite ends: one sec interrupts the impulse, Task Lock removes the option until the work is done.

Where one sec is the better choice

Where Weeklane Task Lock is the better choice

one sec and Task Lock are two of several approaches; the complete guide to app blocking on iPhone compares them with Screen Time, Focus and Shortcuts, and Task Lock vs Opal covers schedule-based blocking. A free middle ground is a Shortcuts automation that bounces you out of an app.

Using both together

They combine well if you split the apps. Put your worst apps (often short video) in Task Lock so they stay shut until today's list is done, and keep apps you only want to be more mindful about, such as news or email, behind a one sec pause. Avoid putting the same app in both: two layers on one app gets confusing fast.
