Opal vs one sec: Blocking Apps or Adding Friction?
These two solve the same problem in opposite ways. One blocks apps outright; the other makes you take a breath first and lets you continue.

The short answer
Choose one sec if your problem is reflexive opening, the hand reaching before the thought. It interrupts the launch with a pause and then lets you proceed if you still want to, which is enough when a large share of your app opens are habitual rather than intentional, and it runs on both iOS and Android. Choose Opal if you have already decided an app should be off-limits during certain hours and want it enforced rather than merely questioned; it is iPhone-only, and firm for the duration of a session. The useful question is whether your problem is impulse or duration. If you open a feed unconsciously and close it again once you notice, friction is enough. If you open it deliberately and then lose an hour, a pause will not save you and you need the block. And if you find yourself routinely tapping straight through the pause, treat that as the answer rather than a failure: you need something firmer.
How they differ
| Feature | Opal | One Sec |
|---|---|---|
| Approach | Blocks apps on a schedule or on demand | Interrupts the launch with a pause, then lets you proceed if you still want to |
| How hard to undo | Firm. It is designed to be enforced during a session | Gentle by design. It never prevents you, it only delays you. |
| Platforms | iOS | iOS and Android |
| Best suited to | Someone who knows which apps are the problem and wants a boundary that holds. | Someone who opens apps without deciding to, and mostly stops once made aware of it. |

Common questions
Which actually works better?
It depends on whether your problem is impulse or duration. If you open a feed unconsciously and close it once you notice, friction is enough. If you consciously open it and then lose an hour, you need the block.
Is a pause really enough?
For some people, yes, a large share of app opens are habitual rather than intentional, and interrupting the reflex removes them. If you routinely tap through the pause, that is useful information: you need something firmer.
