You meant to read a book tonight. You opened your phone to check one thing. That was ninety minutes ago. Paradox puts a guardian between you and the apps that take the most, and gives the time you win back to something worth reading. GUARD THE APPS THAT PULL YOU IN Pick the apps, whole categories and websites you would rather not open, and the hours they are off limits. The wall goes up and comes down on schedule, even while Paradox is closed. Two rules come ready to use on weekdays, a block from 9 to 5 and a 45-minute daily limit, and both are yours to rewrite. A PAUSE BEFORE YOU GIVE IN Open a guarded app and the Paradox shield is there first. If you really do need in, you ask from inside Paradox: your guardian stands in the way, you wait out a short countdown, and you choose 2, 5 or 15 minutes. The pass closes itself when the time is up. FOCUS SESSIONS The Focus tab starts a session: an hour of deep work, half an hour, a quick fifteen minutes, or a length of your own. Your guardian rests by a campfire under the night sky, and the apps you chose stay blocked until the session ends, even while it is paused. Follow the clock on the Lock Screen and in the Dynamic Island, start a session from the Focus widget on your Home Screen, and look back on your week, month and year in the report. SOMETHING WORTH YOUR ATTENTION Grow is a library of short lessons to read or listen to, meant to leave you a little better than they found you. On the pause screen, one tap trades the pass for a read. YOUR NUMBERS, HONESTLY Where today, this week and this month actually went, app by app. Put a daily limit on your apps and watch today fill up. GUARDIANS YOU EARN Every day you keep a block on earns experience, and so does every focus session. Fill the bar to reach a new level, and each level lets you pick a new guardian or a new attack on the guardian tree. The first time you open Paradox each day, your guardian tells you what you earned. Choose the background your guardian stands in. Some of them move, with music of their own. PARADOX PREMIUM Blocking, schedules, focus sessions, statistics and the whole library need no subscription, and there are no ads. Paradox Premium is an optional auto-renewing subscription, monthly or yearly, that opens the premium guardians and their attacks, and the premium backgrounds. Subscribing needs an account, because the subscription belongs to your account rather than to one phone. Each plan shows its period and how it renews before you subscribe, and you can cancel any time in your Apple Account settings. YOUR PRIVACY No ads, and nothing about you is sold to anyone. The per-app times in Stats are drawn by iOS inside a sandboxed extension that cannot hand them to us. We also measure how Paradox itself gets used, and the privacy policy says exactly what that means. NO ACCOUNT NEEDED Blocking, focus sessions, statistics, the library, your level and your guardians all work without signing in. Sign in with Apple or Google to keep your progress on any phone, or to subscribe. Paradox needs Apple's Screen Time (Family Controls) permission, because it is the only way iOS lets one app hold another back. You grant it on your device, and you can withdraw it in Settings at any time. Paradox is made by two brothers. Write to us and one of us will answer.
