ContentNest: Site & App Block

Add a domain to one list and block it across Safari and in-app traffic. A self-control tool that runs locally on your device.

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)
• 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
