WhatA consumer mobile app that acts as an application-level firewall, letting users control which apps can access the internet, when, and what domains they connect to.
SignalA commenter explicitly called out that what both platforms most need is an application firewall — not every app should be allowed to connect to the internet freely, and users want granular control over app network access beyond just notification permissions.
Why NowGrowing privacy awareness, regulatory pressure (DMA, GDPR enforcement), and the proliferation of apps that phone home to dozens of trackers have made users increasingly uncomfortable with unchecked network access from every installed app.
MarketPrivacy-conscious consumers, ~100M+ potential users in Western markets willing to pay $3-5/month. Competes with Little Snitch (Mac only), NetGuard (Android, limited), and built-in Screen Time controls that don't cover network access.
MoatDifficult to build well on iOS due to platform restrictions (would need VPN-based approach); whoever cracks the UX and gets App Store approval first has a meaningful head start. But platform risk is existential — Apple could add this feature or reject the app.
