SFirewall blocks the sites and apps you choose, all the time or on a schedule. An accountability partner holds a 4 digit code, and nothing can be loosened without it.
Built on Apple's Screen Time. Block adult sites, whole categories, single apps (even ones not installed yet), App Store installs, and set daily time limits. An optional Safari extension checks pages for your words. Your partner can link their own iPhone to get alerts.
Available on the App Store.
A system level blocker with a menu bar app. It filters DNS, blocks apps, watches for words on screen, and texts your partner through Messages if anyone tries to get around it. It links with the iPhone app through your own iCloud.
Download the signed Mac installer (macOS 15 or later).
SFirewall has no sign up and no servers of its own. Your settings live on your devices and in your own private iCloud. Read the privacy policy for the details.
