If you've ever wished Apple's Screen Time did more to actually protect your kids online, Gertrude is the answer you've been looking for. Built by Jared Henderson — a Christian, homeschool dad, and programmer — Gertrude takes a "default deny" approach to internet safety: everything is blocked unless you specifically approve it.^1
The flagship Mac app gives parents comprehensive web filtering, screenshot capture, and keystroke logging, all managed remotely from any device. Need to approve a website your child just requested? You'll get a notification and can handle it from your phone.^2 The free iOS app (Gertrude Blocker) plugs the gaps Apple left in Screen Time — blocking GIF searches in iMessage, image previews in Spotlight, thumbnails in Maps, and album artwork in Spotify.^3 And Gertrude AM, their safe podcast app, lets kids listen only to parent-approved shows behind a PIN code.^1
Gertrude is fully open source and collects no user data on iOS.^4
