9to9

Your phone has a bedtime now. 9to9 is a nightly app blocker with one simple rule: the apps and websites you choose go quiet from 9 PM to 9 AM. Every night. No schedules to build. No daily limits to negotiate. Set it once, and let 9to9 handle the rest. ONE RULE, EVERY NIGHT At 9 PM, selected social media, video, news, games, and websites are automatically blocked. At 9 AM, access returns automatically. Calls, texts, alarms, and anything you did not select keep working as usual. WHEN SOMETHING REALLY MATTERS Need to get in? Use five minutes of Temporary Access when you really need it. When time is up, 9to9 quietly blocks your distractions again. SEE THE QUIET ADD UP Track your quiet-night streak, protected nights, and time reclaimed from late-night scrolling. PRIVATE BY DESIGN 9to9 uses Apple’s Screen Time technology. Your selections are represented by opaque tokens and stay on your device. 9to9 never sees which apps or websites you choose. No account is required. WHAT MAKES 9TO9 DIFFERENT Most screen-time apps ask you to build a productivity system. 9to9 gives your phone a curfew. The schedule is always 9 PM to 9 AM. That is the whole idea. No feeds after 9. No feeds before 9. The internet will still be here tomorrow. SUBSCRIPTION 9to9 requires an auto-renewing annual subscription. New subscribers can start with a 7-day free trial. After the trial, payment is charged to your Apple Account unless you cancel before it ends. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.

Verdict
The clearest difference is ads: 9to9 at none against Idea Notes's shown. 9to9 also leads on update cadence (every 2 days vs every 3 weeks). Idea Notes's advantage is iOS requirement (18.6 vs 26.0). On price, in-app purchases and device support there is nothing between them.
