one sec | screen time + focus

App & Website Limit, Blocker

Overview

Features & Capabilities

one sec helps you use social media, games, streaming, dating, trading, and other distracting apps more intentionally. Instead of blocking access completely, it adds a short mindful intervention and friction when you open selected apps, helping interrupt unconscious scrolling habits and improve focus.

Set up one app for free, use the Doom Scroll Emergency Brake and Re-Intervention feature to limit extended sessions, or block websites with the free Safari extension. one sec also supports integrations with Structured and LENGO, offers subscription and lifetime Pro options, and can contribute mindful moments to Apple Health via HealthKit. Research collaborations have reported an average 57% reduction in app usage.

User Reviews

Reviews consistently praise one sec for reducing screen time and promoting mindfulness through an intervention-based blocking approach. The top pros are its focus on slowing usage and its perceived effectiveness at blocking. Common issues involve the paid-subscription model and free-tier limits, setup friction, occasional reliability problems, monetization-driven changes, and potential bypasses. Overall, it’s impactful for many, but its value hinges on accepting the paid model and managing setup and reliability challenges.
Pros
  • Significantly reduces screen time and improves focus by interrupting usage and promoting mindfulness.
  • Intervention-based blocking slows you down without enforcing a strict lockdown, which many users prefer.
  • Effective at blocking apps/websites and can be hard to bypass when active, helping maintain discipline.
  • Many users describe it as worth the price and life-changing for their productivity and digital wellbeing.
Cons
  • Free version is very limited (typically only one blocked app); many features require a paid subscription, which feels like a cash grab to some users.
  • Setup is fiddly and repetitive (requires Shortcuts automation per app and reconfiguration after updates), making onboarding frustrating.
  • Reliability issues exist (interventions may not trigger, blocks may fail, or syncing with Screen Time can be inconsistent).
  • Updates sometimes introduce added costs or features (such as haptic changes) that users perceive as monetization rather than improvements.
  • Blocks can be bypassed or undone (e.g., by deleting automations or using the website), reducing effectiveness for some.
