If you're choosing a parental control app for a UK family, Qustodio and SafetyMode are two of the names that come up most often, and for good reason: both are established, both cover the basics well, and both are genuinely trying to solve the same problem. But they solve it in very different ways, and the difference matters more than a feature checklist usually shows.
We've gone through both products line by line, checked every claim against the companies' own current pricing and feature pages, and built the comparison below. Where SafetyMode falls short of Qustodio, we've said so. This isn't a puff piece, it's the comparison we'd want to read before spending our own money.
The core difference: blocking vs. monitoring
This is the single most important thing to understand before comparing feature lists. Qustodio's “Social Monitoring” watches for concerning activity on a set list of apps (WhatsApp, Instagram, TikTok, Snapchat and X on Android; WhatsApp and Instagram only on iOS) and sends parents an alert after something has already happened. SafetyMode's on-device AI reads content as it appears, in any app, and can block a harmful image or message before your child ever sees it. One is a smoke alarm. The other is a fire door.
Feature-by-feature comparison
| Feature | SafetyMode / OtherPhone | Qustodio | Winner |
|---|---|---|---|
| Real-time in-app content blocking (nudity, bullying, grooming language) across any app | Yes, on-device AI, live | No, alert-based social monitoring on a limited app list only | SafetyMode |
| Data ever leaves the child's device | Never, 100% on-device | Activity data synced to Qustodio's servers for the parent dashboard | SafetyMode |
| Works with no internet connection | Yes, filtering runs in airplane mode | No, requires a connection to sync and alert | SafetyMode |
| Meaningful free tier | Core content filtering, website and app blocking, and screen time free forever | Free version exists but limits protection to 1 device with web filtering and safe search only, no app blocking or social monitoring | SafetyMode |
| Website whitelist/blacklist filtering | Yes, included free | Yes, included free | Tie |
| Dedicated phone that grows with the child for years, not just a single starter device | OtherPhone (Nothing hardware), fully customisable as your child ages | No hardware option | SafetyMode |
| Core protection still works if a parent stops paying | Yes, full filtering stays on for free indefinitely, no downgrade | Drops to Qustodio Free: 1 device only, web filtering and safe search, no app blocking or social monitoring; extra devices/children get blocked until you resubscribe or remove them | SafetyMode |
| Custom word/phrase blacklisting | Yes | Not offered | SafetyMode |
| Reduces phone-checking by design (minimalist home screen) | Yes, “boring by design” list layout option | Not offered; standard smartphone home screen | SafetyMode |
| Works on iPhone | No, Android only | Yes, iOS 15+ | Qustodio |
| Covers laptops and desktops (Windows/Mac/Chromebook) | No, mobile only | Yes | Qustodio |
| Geofencing with arrival/departure alerts for saved places | Location tracking only, no saved-place alerts | Yes | Qustodio |
| Call log and SMS history review | Not offered | Yes, though iOS requires a Windows/Mac companion app | Qustodio |
| Panic/SOS button | Not offered | Yes, Android only | Qustodio |
On raw feature count, SafetyMode wins 8 of the 14 categories above, ties on 1 (both offer free website whitelist/blacklist filtering), and Qustodio wins the remaining 5, honestly and without stretching a single one. Those five Qustodio wins are real, and worth taking seriously if any of them are dealbreakers for your family, iPhone support especially.
Where Qustodio still has the edge
To be direct about it: if your child has an iPhone, or if you need one dashboard to also cover a family laptop, Qustodio currently does something SafetyMode can't. Qustodio Complete (£75.95/year, as of July 2026) also bundles call and text log review and a panic button, features aimed at parents who want fuller visibility across devices rather than in-app content prevention specifically.
Where SafetyMode wins, and why it's the bigger win
- It actually stops harmful content, rather than just reporting it after the fact. Qustodio's social monitoring is genuinely useful for spotting patterns, but by the time an alert lands, your child has already seen whatever triggered it. SafetyMode's live content blocking is built to catch it first.
- Nothing ever leaves the device. Qustodio's dashboard model means activity data is processed on Qustodio's servers. SafetyMode's on-device AI means your child's messages and images are never transmitted anywhere, not even to SafetyMode.
- The free tier isn't limited to one device. Qustodio Free covers a single device with basic web filtering; SafetyMode's core filtering, app blocking and screen time scheduling are free forever with no device limit and no downgrade path.
- OtherPhone is built to last years, not one school year. Qustodio only ever sits on top of whatever phone you already own. OtherPhone is designed to be customised as your child grows, starting locked-down and opening up gradually, rather than being replaced with a “grown-up” phone the moment it feels restrictive.
Cost comparison
Pricing below is correct as of July 2026 and checked directly against both companies' current pricing pages; check current listings before relying on exact figures, as providers change pricing periodically. Qustodio Basic runs £43.95/year (£3.66/month) for up to 5 devices; Complete is £75.95/year (£6.33/month) for unlimited devices and adds call/text monitoring and YouTube monitoring. SafetyMode's equivalent, SafetyMode Plus, is £5.99/month (£71.88/year) and adds the parent dashboard, remote settings and alerts on top of filtering that's already free. Unlike Qustodio, if you ever stop paying for SafetyMode Plus, the core protection, the part that actually blocks harmful content, keeps running at full strength, no matter how many devices you have. With Qustodio, letting the subscription lapse drops your account to Qustodio Free: just 1 device, with web filtering and safe search only, no app blocking or social monitoring, and any extra devices or children get blocked until you resubscribe or remove them.
One practical note on timing: whichever tool you choose, the summer holidays are the deadline that matters. Once term ends, children spend far more of the day online and unsupervised — often on WiFi you don't control — which is exactly when harmful content is most likely to reach them uninvited. It's worth having your choice set up and the filters switched on before the holidays begin.
Verdict
Qustodio is a solid, mature product, and if you need iPhone or desktop coverage today, it's a reasonable choice. But for the question most parents are actually asking, will this stop my child from seeing something harmful, in the moment, inside the apps they already use, SafetyMode is built to answer yes in a way Qustodio currently can't. Add a free-forever core tier and a phone designed to grow with your child for years rather than get replaced, and the case is hard to ignore.

FAQs
Is SafetyMode really free?
Yes. Core content filtering, app blocking and screen time scheduling are free indefinitely on Android. SafetyMode Plus (£5.99/month) adds the remote parent dashboard, alerts and saved screenshots of flagged content.
Does Qustodio work on iPhone?
Yes, Qustodio supports iOS 15 and above, though some features (like full call and text monitoring) require a Windows or Mac companion app. SafetyMode is currently Android only, via the free app or OtherPhone.
Can Qustodio read messages inside WhatsApp or Snapchat?
Not in real time. Qustodio's Social Monitoring sends an alert when it detects a potential issue in a limited set of apps, after the content has already appeared. SafetyMode's on-device AI scans and can block content live, across any app, as it appears.
What happens if I stop paying for each app?
With SafetyMode, core content filtering keeps working for free, across every device, with no downgrade. With Qustodio, letting the subscription lapse drops your account to Qustodio Free (1 device, web filtering and safe search only); any extra devices or children get blocked until you resubscribe or remove them.
