The average person spends over 4 hours a day on their phone. That's 28 hours a week, two months a year, Kairos is a tool to help you win that time back. You choose which of your own apps steal your attention. Kairos blocks them - on a schedule you set, or the moment you decide. WHAT YOU CAN DO - Block Now: One tap kills your distracting apps. No setup, no negotiation. - Set Limits: Give any app a daily ceiling. Hit it and the app closes until tomorrow. - Schedules: Build blocks that repeat - mornings, work hours, dinner, nights. - Block Anything: Apps, whole categories, and websites. - The Shield: A block screen that holds. Not a nag you swipe past. - Honest Insights: The visits you caught, the hours you kept. - Streaks: Build a run toward a daily goal you set yourself. NEW: SET LIMITS Give an app its own daily ceiling - Instagram, two hours. When you hit it, that app closes for the rest of the day. The decision gets made once, in the morning, by the version of you that meant it. Not a hundred times between then and midnight, by the version of you that's tired. WHY IT WORKS Most screen time tools ask you to have willpower at the exact moment you have none. Kairos moves the decision earlier, to when you're clear-headed, and then holds the line for you. No points. No streaks to perform for anyone else. No cartoon tree that dies. Just the apps, closed, until you meant them to be open. PRIVACY Kairos is a self-monitoring tool: you set limits on your own device to reduce your own screen time. It's built on Apple's Screen Time features, and your app selections never leave your phone - Kairos can't see which apps you picked, and neither can we. App Privacy: No Data Collected. Put the phone down. Keep the day.

Verdict
The clearest difference is rating: Kairos at 5.0 against Blocus's 4.5. Blocus's advantage is ratings volume (226 vs 1) and update cadence (every 3 days vs weekly). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Blocus sells 10 in-app purchases, starting at $9.99 per month and Kairos sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Kairos holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Blocus has 226 ratings behind it against 1, so its average is the more settled of the two.
Blocus ships an update every 3 days, Kairos weekly. Both last shipped on November 5, 2026.
