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.

| Weeklane Task Lock | one sec | |
|---|---|---|
| Core idea | Lock chosen apps until today's tasks are done | A short pause (breathing, a question, a task) before an app opens |
| Can you still open the app? | Not while today has open tasks (optional 15-minute break) | Yes, after the pause; Pro can also fully block during sessions or schedules |
| To-do list | Yes, the core of the app | No; integrates with the Structured planner to block during unfinished tasks |
| Platforms | iPhone and iPad (Android planned) | iPhone, iPad, Mac, Android and browser extensions |
| Privacy approach | Apple Screen Time API; Weeklane never sees which apps you use | Says interventions run on the device and data is not sold |
| Free plan | Free weekly planner; Task Lock needs Pro | Breathing pause for one app |
| Paid plan (US) | Pro: $4.99/month or $34.99/year, 7-day free trial | Pro: $19.99/year, $6.99/month or $99.99 lifetime; family plans available |
Where one sec is the better choice
- You want friction, not a wall. Many people do not need a hard block. A pause is often enough to break the reflex, and one sec reports a large average drop in app use from its research.
- You use many devices. one sec covers iPhone, iPad, Mac, Android and browser extensions with one account. Task Lock is iPhone and iPad only for now.
- You want variety and reflection. Breathing exercises, intention prompts, re-interventions after a few minutes and scheduled interruptions give you lots of ways to tune it.
- Low price for a dedicated tool. If you only need an interrupter, one sec's yearly plan is inexpensive.
- You already plan in Structured. one sec can link to the Structured planner to block apps while tasks are unfinished.
Where Weeklane Task Lock is the better choice
- Pauses stopped working for you. If you breathe for ten seconds and open TikTok anyway, a lock that only lifts when the list is done removes the decision entirely.
- You want the list and the lock in one app. No integrations to set up. The lock screen shows how many tasks are left and opens Weeklane in one tap.
- Your day has timed tasks. Tasks with a time later today do not lock anything until their time, so the lock follows the shape of your day.
- You also want a planner. Weeklane Pro also includes reminders, recurring tasks, connected calendars and shared projects.
- Privacy. Weeklane never sees which apps you choose or how you use them.
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.
Frequently asked
What is a good one sec alternative?
If you like the pause, other intervention apps work similarly. If you want a stronger rule, Weeklane Task Lock (since Weeklane 2.5) keeps chosen apps locked on iPhone and iPad until today's to-do list is done.
Does one sec block apps completely?
Its main feature is a pause before an app opens, after which you can still continue. According to one sec's own FAQ, Pro can also block apps or sites completely during a block session or scheduled time.
Is one sec or Weeklane Task Lock better for doomscrolling?
If a moment of reflection is enough to stop you, one sec is lighter and cheaper. If you tap through pauses, a task-based lock like Weeklane Task Lock is harder to ignore because the apps stay locked until today's tasks are done.
How do one sec and Task Lock differ from iPhone Screen Time?
Screen Time limits unlock by time. On iOS 27, the limits you set for yourself apply to whole categories such as Social, plus a daily total, not single apps, and there is no Ignore Limit button when time runs out. one sec adds a pause before the specific apps you choose, and Task Lock keeps the individual apps you pick locked until today's tasks are done.
Is Task Lock on Android?
Not yet. Task Lock is on iPhone and iPad, and an Android version is planned. one sec already supports Android.
How much do one sec and Weeklane Pro cost?
On the US App Store, one sec Pro is listed at $19.99/year, $6.99/month or $99.99 lifetime, with regional prices that can be lower. Weeklane Pro, which includes Task Lock, is $4.99/month or $34.99/year with a 7-day free trial.
