With Accountable2You your ally reads page titles. With Open Book your ally reads event types — that something happened, never what.
What Accountable2You does on iPhone
Their iOS page says the app monitors all major browsers including Safari and Chrome with detailed real-time reporting, regular reports and instant alerts to accountability partners — and that its VPN technology for iOS records internet activity in Safari, Chrome, or any browser used, showing the title of each page viewed, rated for concern, with reports updated in real time (source: accountable2you.com/ios/, current as of Sep 22 2026). The same page is candid about iOS limits: activity inside non-browser apps such as Facebook, Instagram, and TikTok cannot be reliably monitored, while Screen Time can at least block new installs.
Their monitoring page breaks it down by platform: on iOS, all major browsers, private browsing, circumvention and uninstall tracking, and custom trigger words are covered; app usage and YouTube are limited; social media is in-browser-only; calls and texts are not covered on iOS (source: accountable2you.com/monitoring/, current as of Sep 22 2026).
What Open Book does instead
No VPN, no recording, no titles. Open Book enforces Apple's adult website filter in Safari and shields for apps or categories you choose, on-device. Allies see protection-related event types and check-in status only, with status-free texts that say to look at the dashboard. Up to five allies join free.
