one sec review
A cross-platform blocker with configurable interventions, schedules, strict sessions, and tracking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
one sec is a distraction-blocking and screen-time app for people who want more intentional technology use. It places configurable interventions before selected apps or websites open, and it can block chosen targets during active or scheduled sessions. Coverage includes Windows, macOS, Linux, iOS, Android, and a Chrome extension, making it suited to people who want similar controls across devices rather than a single-platform blocker.
The product uses a freemium model with a free plan and a seven-day free trial. The published Pro highlights include unlimited apps, website blocking, strict block sessions, and time tracking. Pro Lifetime provides lifetime access to Pro features, while Family Plan offers a family subscription and Family Lifetime provides lifetime family access. The listed starting price is 1.67, and prices vary by region. Buyers should compare the applicable regional listing before choosing between recurring and lifetime options.
one sec’s standout area is the combination of intervention-based friction and scheduled blocking. Users can set recurring schedules by weekday and time, use strict sessions that prevent pausing or leaving early, and review progress through time tracking and statistics. Website blocking works through browser extensions, while adult-content filtering adds another control layer. Integrations with Structured and Lengo support a focused ecosystem, but buyers seeking a wider integration catalog may prefer another option. Choose one sec for cross-platform blocking with configurable interventions; avoid it if flexible sessions or broad integrations matter more than enforced blocking.
