Try I'm Alive FreeWhat Is Demumu?
Demumu, developed by Moonscape Technologies, is a daily safety check-in app that went viral in January 2026 — reaching #1 paid app in China and #6 in the US App Store. The app asks users to confirm they're alive periodically, and sends an email notification to a designated contact if they don't respond.
The concept resonated with millions of people, especially those living alone, seniors, and solo travelers. Demumu proved there's massive demand for simple, dignity-preserving safety check-in apps.
I'm Alive was built with the same mission — but takes a different approach to alerting, pricing, and platform support. Here's how they compare.

Key Differences Explained
Smart Escalation vs Single Alert
The biggest difference between the two apps. Demumu sends a single email if you miss a check-in. I'm Alive Premium users get a 4-stage escalation system that reduces false alarms while catching real emergencies faster. Free and Lifetime users get a reliable email alert — simple and effective.

Cross-Platform: iOS + Android
Demumu is currently iOS-only. I'm Alive works on both iOS and Android — critical for families where members use different phone platforms. Nearly half of US smartphone users are on Android, and globally the number is even higher. A safety app that only works on one platform leaves gaps in family coverage.
Privacy-First Approach
Both apps respect user privacy — neither tracks GPS or location. I'm Alive collects minimal data: email, name, and check-in timestamps. No surveillance, no tracking, no data selling. Both apps are built on the principle that safety shouldn't require giving up privacy.
Pricing Philosophy
Demumu uses a weekly subscription model. I'm Alive offers a permanently free tier (no account needed), a $0.99 one-time Lifetime purchase for customization (normally $3.99 — 75% off for a limited time), and an optional Premium plan at $2.99/month for families who need smart escalation, SMS alerts, and up to 10 contacts. We believe basic safety check-ins should be accessible to everyone — without even creating an account.
Which App Should You Choose?
Choose Demumu if you want...
- •Ultra-minimal interface with no extras

Frequently Asked Questions
What is Demumu?
Demumu (by Moonscape Technologies) is an iOS-only daily check-in app that went viral in January 2026. It asks users to check in periodically and sends a single email to a contact if they don't respond. It gained popularity through social media and press coverage.
How is I'm Alive different from Demumu?
I'm Alive offers a free tier with no account required, works on both iOS and Android, includes check-in notes, and Premium users get a 4-stage smart escalation system with SMS alerts and up to 10 contacts. Demumu is iOS-only with a simpler single-alert approach.
Is I'm Alive really free?
Yes. The Free plan includes daily check-in, email alerts, and 1 contact — free forever, no account needed. The Lifetime plan is $0.99 one-time (normally $3.99 — limited time 75% off) and unlocks custom times, notes, and alert testing. Premium at $2.99/month adds 4-stage escalation, SMS alerts, and 10 contacts.
Does I'm Alive work on Android?
Yes. I'm Alive is available on both iOS (App Store) and Android (Google Play). Demumu is currently iOS-only, which means families with mixed devices can't use it together.
What is smart escalation and why does it matter?
Smart escalation (Premium feature) means we don't immediately alert your contacts when you miss a check-in. Instead, we send you multiple reminders first (at check-in time, +30 minutes, +2 hours) before sending an urgent alert at +6 hours. This dramatically reduces false alarms. Free and Lifetime users get a reliable email alert to their contact.
Can I switch from Demumu to I'm Alive?
Yes, switching takes under 30 seconds. Download I'm Alive — no account needed — set your check-in time, add your contact's email, and you're done.
Which app is better for seniors?
Both apps are simple to use. I'm Alive has a slight edge for seniors because it works on Android (many seniors use Android), has a larger one-tap check-in button, and the escalation system reduces unnecessary worry for family members.
Does I'm Alive track my location?
No. I'm Alive does not track GPS, location, or any surveillance data. We only record that you checked in and when. Your privacy is protected.
