Caspian Defender

An Android app that blocks apps and websites on the phone it is installed on. The ways past a block are set up in advance and cost something at the time: rules that block or slow sites through a DNS-only local VPN, a countdown before an app opens that grows with each open, a guardian key held by someone you trust, safe search for Google, Bing, DuckDuckGo, Yandex and YouTube, optional uninstall protection, and an urge map of when the pull is strongest. No account, no server, no analytics, no ads — everything stays on the device.
