Worth knowing
Jomo
- Apple devices only: iPhone, iPad and Mac. Jomo's pages list no Android or Windows version.
- The free plan allows 1 Session, 1 Action or Limit and 1 Screen Time Budget.
- Strict Mode, the Apple Health integration and multiple Screen Time Budgets need Jomo Plus.
- The help center says only the lifetime plan can be shared with family, yet the US App Store also lists Jomo Plus Family at $11.99 a month and $59.99 a year.
one sec
- The free version covers a single app or website; adding more needs one sec pro.
- The price depends on where you buy: one sec's web store charges $3.99 a month in the US, while the US App Store lists the monthly purchase at $6.99.
- No Windows or Linux desktop app is listed; on those systems one sec runs only as a browser extension.
- Not every Pro feature is on every platform: the help center's table marks strict block sessions and website blocking as unavailable on Android.
Key features
Jomo
- Sessions
- Block chosen apps for a set duration or inside a time range, such as an hour of deep work or 9 PM to 6 AM, at a blocking strength you pick.
- Limits and Actions
- A Limit blocks apps after a set amount of use, such as 10 minutes. An Action keeps them blocked until you do something first, such as walking 5,000 steps.
- Unlocks
- Opening a blocked app can require waiting a few seconds, giving a reason, copying out a text, entering a password, scanning a QR code or showing proof.
- Strict Mode
- Makes rules impossible to delete or bypass, for a set time, while blocking, within a time range or always. It is part of Jomo Plus.
- Journaling and reports
- After a session you record whether the app was worth the time, and reports show usage patterns so you can decide what to block.
- Mac app
- Blocks apps, websites and keywords on the Mac in all browsers, with no extension needed except for Firefox. Focus Filters switch on the same rules on iPhone and Mac together.
one sec
- Interruptions before an app opens
- A short pause appears before a chosen app or site opens. Types include a breathing exercise, a mirror, a math task, rotating the phone and typing random text.
- Re-Intervention
- After a set time inside an app, for example 5 minutes, one sec sends you out and asks you to go through another interruption to unlock more time.
- Block sessions and schedules
- Chosen apps and sites can be blocked completely during a block session or at scheduled times, and interruptions can be limited to set weekdays and hours.
- Browser extension
- Adds interruptions and blocking to websites in Chrome, Firefox, Safari and Edge on Windows, macOS and Linux, under the same account as the phone apps.
- Intention and emotion tracking
- Prompts ask why you are opening an app or how you feel, alongside journaling and nudges toward alternative activities such as reading or calling a friend.
- Progress statistics
- Charts and comparisons show how app use has changed and how much time the interruptions have saved.
