ContentNest blocks specific website domains across Safari, in-app WebViews, and native app API requests with one editable list. Add a domain like "twitter.com", turn on blocking, and the connection is dropped at the DNS layer. ■ Who it's for - Anyone trying to break a habit of checking SNS / news / gambling / adult sites - People disappointed by other blockers that can be bypassed via Settings → Screen Time - Productivity / focus / deep work users who want a hard block, not a soft nudge - Users tired of subscription-based blocking apps ■ Main features - Up to 5 blocked domains free, unlimited with Pro - On-device VPN (NEPacketTunnelProvider) blocks both Safari and in-app traffic - Paste any URL — domain is auto-extracted (https://, www., paths, ports stripped) - Check permission, VPN, and latest-list status in one place - Add the current Safari site directly from the Share menu - Subdomain support (e.g. api.example.com only blocks that subdomain) - Set once, runs forever — no daily check-in needed - Switch between lists for your device and your child's iPhone - Send the child list with an invitation link - Check the child's latest sync and protection status ■ Pro (one-time, USD 4.99) - Unlimited blocked domains (free is 5) ■ Why we made it - Domains, URLs, browsing history, and blocked content are never sent to us or Analytics - Anonymous usage events are sent only after explicit consent and can be disabled anytime - Family lists are shared through the user's own iCloud (Apple CloudKit) - No subscription — Pro is one-time only - Zero ads - No login required ■ Not in scope (intentionally) - URL path-level blocking (domain-level only) - Ad DOM element hiding (DNS-layer filter — first-party ads are not blocked) - Privacy / anonymity VPN (this VPN is for local domain filtering only) - Per-app blocking, time limits, and location sharing ■ Requirements - iOS 17.0 or later - VPN Allow dialog must be approved once
