one sec | screen time + focus

App & Website Limit, Blocker

Features & Capabilities

one sec introduces friction to distracting apps rather than outright blocking, helping you build lasting focus. Backed by research, it reduces screen time by diminishing the appeal of social apps and supports long-term habit change.

Key features include delaying access (not fully blocking), a Doom Scroll Emergency Brake (Re-Intervention), a free Safari extension, Shortcuts automation, and optional Pro upgrades. It also integrates with HealthKit and supports ADHD-friendly use, offering a practical path to reclaim focus and productivity.

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.

I used to love using one sec, but after an update the app now includes very annoying haptics that aren’t possible to remove without upgrading to the paid version. I guess I’m not surprised, as every decent app eventually makes updates that no longer serve its free users. I’ll be looking elsewhere for another app. So long, one sec, and so long your annoying haptics that I refuse to pay money to remove.

Correct me if Im misunderstanding anything. This is coming from a developer of multiple years first of all let’s start off with how almost every single feature is paid. I know that the you developers need the payment to continue working on it well, but some features that are behind a paywall are GENUINELY necessities that shouldn’t cost a dollar. For example you can’t even intervention block more than a single app without getting the subscription, and if you tested the app well you would know that most people need to block more than 1 app. Surprise surprise if TikTok is blocked I’ll just switch to Insta. second I shouldn’t have to create a shortcuts automation every time I add an app to one sec. other focus apps allow you to block multiple apps in seconds. “linking” an app twice for each block/intervention is a bit redundant, it should just let me choose what apps i wanna block from a list. then there’s the fact there’s very little securing of your blocks unless you pay. it’s TOO easy to just delete the Shortcuts Automation to stop the app blocking forever, or just use the TikTok.com instead of the TikTok app (cause strict blocking is paid too…) It’s also REALLY annoying how a bug fix was turned into a Pro feature (Intentional App Switching). Normally if you got timed out from an app, you would close the app for 5 minutes, take a break, and come back after 5 minutes. Well with one sec you have to wait the full 5 minutes INSIDE the app to be able to use it again, or you’ll have to wait for the timeout to expire every, single time you reopen the app. Only way to fix this? get pro which is stupid The last straw was when the stupid intervention feature wasn’t working properly at all. I needed to use YouTube for an emergency but every time I went through the intervention YouTube was still blocked. Don’t make so many features paid if the basic ones aren’t even working properly. Developer, correct me if I misunderstood anything but in my opinion it’s not the most effective and a bit cash grabby. there are other focus apps like Opal with the same features for free

I really love one sec. I have it downloaded on my phone and web browsers. It's an amazing value. I love how it slows me down throughout the day, because switching from digital activity to digital activity can be so fast and happen very easily for me just for dopamine instead of being something that I actually want to do once I take a few moments to breathe in and reflect. I actually have it turned on for apps I do like to use like Gmail or Messages or Spotify to so I can get some extra moments of mindfulness and breathing throughout the day.
