For studying
A website blocker for studying that pays you in breaks.
Study first, then play, without the guilt. Onus seals the sites that eat your evenings and opens them again in breaks you've earned: every 25 minutes of study buys 10 minutes of play.
Breaks you can see coming
A timer tells you to stop. Onus tells you what you've earned. The bank on the toolbar fills while you work on your study sites, so you always know your next 25 minutes are worth 10 minutes of YouTube, and the break feels like yours.
How it works
- Seal the sites that pull you away, like Reddit, YouTube, X or Instagram. Their subdomains are sealed too.
- Pick your work sites, like Google Docs, GitHub, Notion or your course pages. Active time there fills a bank.
- Spend from the bank. Open a sealed site and Onus offers 5, 10 or 15 minutes from it. When the time runs out, the seal comes back.
Every 25 minutes of work buys 10 minutes of play. The bank holds up to 2 hours and resets at midnight, and five emergency minutes a day never touch it.
Built for how students study
- Study sites earn. Google Docs, Notion, Quizlet, Khan Academy, your course pages: you choose what counts.
- Off-screen study counts too. Start Focus for 30 minutes, an hour or two, read your textbook, then say "I worked". It earns up to 2 hours a day.
- Plain YouTube. When YouTube opens, the feed, Shorts and suggestions stay hidden, so a lecture video doesn't turn into an hour.
- Exam weeks. Sealed hours, strictness levels and a lock of up to 30 days keep the seal on when it matters most.
- See your study. Today shows the hours you got the most done, and a receipt of your day.
Price
The free plan keeps the bank, the seal and emergency minutes with 2 sealed sites and 1 study site. Full Onus is $29.99 a year or $59 once, with a 7-day free trial.
