One Sec vs Clearspace: Which Friction Lasts?
Both apps will slow you down. Neither will stop you. That’s the design — and it’s worth saying plainly before any comparison, because people still buy friction apps expecting a wall. One Sec and Clearspace are delay mechanisms, not locks. The relevant question isn’t “which blocks better” but “which annoyance do I tolerate long enough to actually change behavior?”
What each app actually does
One Sec intercepts an app open with a mandatory breathing animation — a few seconds of forced pause, configurable longer. You breathe in, you breathe out, then you decide whether to continue. The theory is that the urge dissolves in the gap. Often it does. Sometimes you breathe and open Instagram anyway, which the app doesn’t punish.
Clearspace replaces the urge-response loop with a small physical challenge: pushups, jumping jacks, or similar. You complete a set before the app opens. The friction is higher by design. Ten pushups takes longer than one breath, and it’s embarrassing in public in a way that a breathing pause is not.
Both are iOS only. Both cost money on an ongoing basis. Neither integrates with Screen Time at the system level in a way that’s genuinely bypass-proof — you can always open a blocked app through Settings if you want it badly enough.
The annoyance budget problem
Friction apps have a finite annoyance budget with any given user. Every time the intervention fires and you notice it as a nuisance rather than a useful pause, you spend a little of that budget. When the budget hits zero, you disable the app — or more likely, you stop adding new apps to it, so it gradually becomes irrelevant.
One Sec’s breathing animation starts pleasant. Week one, it feels mindful. By week four, a meaningful subset of users find it condescending. The animation doesn’t change; your relationship to it does. App Store reviews describe exactly this arc: loved it, then started resenting it, then turned it off.
Clearspace has a different problem. The pushup mechanic is high-novelty friction — unusual enough to command attention for longer. But the ceiling is higher too. Getting caught doing jumping jacks in a meeting because you reflexively tried to open Slack burns annoyance budget fast. And if you disable it during work hours for social reasons, you’ve created an exception window that tends to expand.
Neither app has solved this. They’ve picked different annoyance curves.

Clearspace costs more. One Sec has been around longer, which means a more stable feature set and more third-party reviews to read before committing.
Who each one is actually for
One Sec fits people who want a quiet, private intervention. The breathing animation is invisible to anyone around you. It’s the right tool for someone who checks Twitter in meetings, on the bus, waiting in line — social situations where doing pushups would be bizarre. It’s also right for people who’ve already built some self-awareness about their opening patterns and just need a small interrupt to make the habit conscious.
Clearspace fits people who’ve tried gentler friction and found it insufficient. If you’ve run One Sec (or something like ScreenZen) and disabled it after a month because the intervention felt too easy to push through, Clearspace’s higher physical cost holds longer. The embarrassment factor in private settings — home, alone — is an asset. Nobody wants to do jumping jacks at midnight.
Neither is right for someone who needs genuine blocking. For that, look at something operating at the network or Screen Time level, like the options in the app blockers ranked by job.
The honest verdict
One Sec has a lower annoyance ceiling, which means more people finish month one without disabling it. Clearspace demands more from you, and the people still running it at month two have self-selected hard enough that it’s probably working.
“Probably” is doing real work in that sentence. Neither company publishes retention data.
If you’ve never tried either: start with One Sec. Lower cost, lower stakes, and if it works you never needed the pushups. If One Sec failed you specifically because the breathing felt too easy to blow through, Clearspace is the logical next step rather than abandoning friction entirely.
If both fail you, that’s not a product problem. Some phones need a wall, not a speed bump — a Brick-style hardware commitment or a scheduled block you can’t easily override. Friction apps are a category with a ceiling.
