Gertrude makes devicestruly safe.
Keeping pornography and other harmful content off your devices shouldn’t be a losing battle. Gertrude gives you strict control over what’s accessible, closes the loopholes other tools leave open, and provides real accountability for how devices are used.
Gertrude for Mac
Everything blocked, except what you approve. Gertrude blocks the entire internet on a Mac, then unlocks only the websites and apps you choose.
Temporary access, with oversight. When they need something that isn’t normally allowed, they can ask for temporary access. Monitoring stays on, and the filter turns back on by itself.
Honest by design. They can always see that the filter is on and what’s being recorded, right from the menu bar. No hidden spying.
Strict, not frustrating. If a site they need is blocked, they can send you a request straight from their Mac. You get a notification and can unlock it from anywhere.
Accountability without hovering.Gertrude can capture regular screenshots and everything typed, so parents and accountability partners can review activity on their own time. Activity during temporary access is highlighted, and you can flag anything worth a conversation.
Free to start.
Try Gertrude for Mac free for 21 days, no credit card required. After that, it’s $10 a month for your whole family, with Gertrude Blocker, Music, and Podcasts included.
Gertrude Blocker
Close the gaps in Screen Time. Gertrude Blocker works alongside Apple’s parental controls to block GIF search, web image results, explicit album artwork, and other loopholes Apple leaves open. It’s free.
Block whole categories with one choice.Turn on protection for GIFs, Spotlight searches, ads, AI features, music artwork, and more. Choose what fits each device, and change it anytime from your Gertrude account.
Blocked Groups
These content categories are blocked on this device.
Let’s talk about
media.
An endless catalog is impossible to monitor.Control what’s available instead.
Music and podcast apps put millions of songs and shows one search away, including sexual, violent, and deeply disturbing content. Explicit labels catch only a fraction of it, and no parent or accountability partner can inspect every result or recommendation.
Gertrude replaces open-ended browsing with a library you control. Decide exactly which music can play, and require your PIN before any new podcast is added.
Gertrude Music
The music you choose. Nothing else. Gertrude Music starts with an empty library. You add the artists and albums, and they get a beautiful, full-featured music app, with no searching beyond what you’ve chosen.
A full-featured player. Shuffle, repeat, and keep the music going with Infinite Play.- Rich artist pages. Top songs and albums for every artist you add, on iPhone or iPad.
- Their whole collection, at a glance. Every artist and album you’ve added, beautifully organized and ready to play.
Try it free for 21 days, then $5 a month for your whole family.

Real relief, in their own words.
“Thanks for the hard work you put into making this app. An absolute masterpiece and likely the greatest blessing an app has had on our lives. Thank you again. Words can’t explain how grateful I am for your sacrifice.”
Austin944 “Saved my young son from looking at porn through the maps app. You are a lifesaver.”
GratefulMom55 “Finally a way to block GIFS!!! Thank you, thank you, thank you!!!”
HAAS1988 “We are giving out 16-year-old son his first phone, and we feel comfortable doing so with Gertrude, knowing how trustworthy it is. We couldn’t rely on any other blocker.”
Josue & Keren “Using this for my kids’ iPhones with Apple Configurator and screen time controls has made the phones far safer as the kids learn to use them responsibly. Many thanks to the developer for a great and needed tool!”
sraragan “So far so good! An abundance of thanks!!”
SonsMomma “Probably the best app out there for those wanting to walk in sexual purity”
Jesus Is My Reward 510! “Thank you so much for helping us keep our kids safe. An answer to prayer. The app does just what I need it to do in conjunction with screen time.”
“I am so tired of the garbage the world is forging down our kids. Thank you for an easy quick solution.”
HackerFam “Get this app and use it - Apple should have built all of these capabilities into ScreenTime, tbh, but they didn’t so kudos to Gertrude for making this and for making it free. Highly recommend!”
TMTM226 “This app is meeting a great need since Apple has not allowed parents to properly protect their children. Thank you Gertrude Blocker.”
Apple280 “It’s amazing I can’t rave more. I can give my kids more access to things knowing there’s no backdoors to harmful content!”
4bkj “Thank you for creating this app. This is a life saver”
sebvtg “Finally some help for parents! Ever since the iOS 17 update, there has been no way to block inappropriate GIFs. I have emailed Apple, written paper letters, posted on Apple message boards but to no avail. Thank you for creating this app!”
Tiggy1234 “Apple Screen Time has some helpful features, but there are a few glaring holes in its capabilities that allow kids to easily access adult images in really easy ways. Gertrude Blocker plugs the holes the Apple missed, and finally gives parents the ability to put a safe phone in their kids’ hands. Thanks for making this!!”
Henderjay “We try to keep our kids’ phones in a state where they are unable to view porn. Apple does a good job giving parents controls but they left a couple of holes! This is the only app that I know of that fills in those holes. Thank you!!”
khgghdgg “I am SO thankful and blessed that I found your product! If you were charging money, I would have paid whatever you asked for this app. It has been exactly what we needed. My husband and I have 6 kids (5 sons), and after IOS 17 update, we were about to make our boys go back to Gabb phones because of the loopholes Apple introduced.”
