Still OK vs Demumu: Which Safety Check-In App Is Right for You?
Since Demumu went viral in early 2026, millions of people have discovered the concept of a safety check-in app. Since then, the original app has become unavailable on the App Store, and a number of copycat apps have appeared in its place. Here's an honest, factual comparison — and why Still OK is the stable, GDPR-compliant alternative.
What Both Apps Do
Both Still OK and Demumu work on the same principle: you check in regularly to confirm you're okay. If you miss a check-in, your emergency contacts are notified. It's a digital dead man's switch — simple, effective, and potentially life-saving.
Where They Differ
| Feature | Still OK | Demumu |
|---|---|---|
| Pricing | Free + Premium (€4.99/mo) | One-time purchase (~€1) |
| Setup complexity | Guided onboarding (60 sec) | Minimal, very simple |
| Email alerts | Yes (free) | Yes |
| WhatsApp & SMS | WhatsApp incl. + SMS credits | No |
| GPS location in alerts | Yes (Premium) | No |
| SOS button | Yes (Premium) | No |
| Check-in intervals | Twice daily – once a month | Fixed (~48h) |
| Languages | 45 languages | ~10 languages |
| Notification language | Per-contact language selection | App language only |
| Home screen widgets | Yes (iOS + Android) | No |
| Vacation mode | Yes (free) | No |
| Ad-free | Yes (even free version) | Ads in free version |
| GDPR compliant | Yes, EU data centers | Not documented |
| Data export / deletion | One-tap export + delete | Not documented |
| Made in | Europe (Germany) | China |
Privacy: The Biggest Difference
If you live in Europe — or simply care about where your data goes — this is the key distinction. Still OK stores all data exclusively in EU data centers and is fully GDPR compliant. No tracking, no behavioral analysis, no data selling. You can export all your data or delete your account with one tap.
Demumu was developed in China. For many European users, this raises questions about data protection, GDPR compliance, and long-term data sovereignty that remain unanswered.
Notifications: Not Just Push
Demumu primarily relies on push notifications, which require the recipient to have the app installed. Still OK takes a different approach: your emergency contacts are notified via email (free) and WhatsApp & SMS (Premium) — no app installation required. WhatsApp is the primary channel; SMS serves as fallback for contacts without WhatsApp.
With Premium, Still OK also includes your GPS location in emergency notifications, so your contacts know where to find you.
Who Should Choose Still OK?
- Anyone living in Europe who wants their data to stay in the EU
- People whose emergency contacts don't want to install another app
- Users who want WhatsApp & SMS alerts — reaching contacts directly on their phone
- People with international contacts (45 languages, per-contact selection)
- Anyone who values a completely ad-free experience
Is Demumu still available?
As of June 2026, the original Demumu app (developer Moonscape Technologies) can no longer be found on the App Store — not even in the US or China, where it first became popular. What to keep in mind:
- The viral original is gone — you can't build a reliable safety net on it.
- Instead, copycat apps of unknown origin are circulating in the store; for a safety app, that's a real risk.
- Where your data ends up with these apps, and whether GDPR applies, is not documented.
- Still OK is consistently available (App Store + Google Play), GDPR-compliant, and actively developed in Germany.
Try It Free
Still OK's free version includes email alerts, daily check-ins, one contact, vacation mode, widgets, and streak tracking — completely ad-free. Premium adds WhatsApp & SMS, GPS, SOS, flexible intervals, and unlimited contacts.
Frequently asked questions
Is Demumu still available in the App Store?
As of June 2026, the original Demumu app (developer Moonscape Technologies) can no longer be found in any App Store — not in Germany, the US, or China, where it first went viral. In its place, a swarm of copycat apps of unknown origin now use the name. The viral original is gone, so you can't build a reliable safety net on it.
What is the best alternative to Demumu?
Still OK is the closest alternative that's actually available and built to stay. It works on the same check-in principle — you confirm you're okay, and if you miss a check-in your contacts are notified — but it's hosted in the EU, GDPR-compliant, and reaches your contacts across email, WhatsApp, and SMS. There's a free ad-free version, so you can try it before deciding.
Is Demumu GDPR compliant?
Demumu was developed in China, and its data handling and GDPR compliance were never publicly documented. For people in Europe, that leaves real questions about where the data goes unanswered. Still OK takes the opposite approach: all data is stored exclusively in EU data centers, it's fully GDPR-compliant, and you can export or delete everything with one tap.
What does Still OK cost compared to Demumu?
While it was available, Demumu was a one-time purchase of around €1. Still OK has a completely ad-free free version, with Premium at €4.99/month or €34.99/year for WhatsApp, SMS, GPS in alerts, SOS, and unlimited contacts. To be honest, price was never Still OK's main argument — availability, data protection, and multi-channel alerts are. A safety net only helps if the app behind it is still there.
Are the Demumu copycat apps safe to use?
It's hard to say, and that's the problem. The apps now using the Demumu name come from unknown developers, with no documented privacy practices or data location. For an ordinary app that might be tolerable — but for a safety and check-in app that handles your contacts and possibly your location, unknown provenance is a real reason to be cautious.
Do my contacts need an app to be notified?
No. With Still OK, your emergency contacts are reached by email, WhatsApp, and SMS — none of which require them to install anything. They receive an ordinary message that names you and explains you didn't check in. Your contacts only need a phone; they never have to sign up for Still OK or any specific app.
