## What is Dead man's switch app?

DMS is a safety, security, and secrecy application used to delivery a encrypted "package" in the event of your absence. 

Who it's for: 
- ordinary person planning for the unexpected
- military person or person in a state of war
- person in poor health wishing to delivery an "emotional will"
- adventure seeker undertaking extreme challenges
- professional journalist working in dangerous environment
- activist protestor exercising rights against injustice
- crypto bro that self-custodies their digital fortune
- solo dweller, traveller, or hermit living alone  
- pirate with a treasure chest full of gold

How it works:
- the app is used to create a "package" on your device that is then uploaded and stored securely in the cloud*
- detection of your presence is determined by Steps, Email, or SMS†
- in the event of your absence, your recipient(s) will be contacted by email and your "package" will be delivered

What ifs:
- if you enable Steps but don't step, you'll be prompted with a notification before you are sent an email 
- if you lose your phone or delete the app, you'll be sent an email to confirm your presence
- if you are captured, you can configure your detection schedule beyond 4 weeks 

Delivery: 
- this app is really about the recipient, not the user 
- in the event of your absence, our compliance team will review and reach out to you before delivery occurs
- when delivery occurs, your recipient(s) will be notified and given their "package"
- recipient delivery is easy enough for your grandma to understand

### 5/5 — Works well

*2026-01-14*

Developer worked out the kinks and is working smoothly.

### 5/5 — Interesting concept

*2025-12-21*

I’ve tired similar services this one seems most friendly and I’m able upload and encrypt files directly from my iPhone.

### 5/5 — Exactly what I was looking for

*2025-09-11*

I’ve tried out the app and it works for exactly what I need it for. If ever I “disappear”, I have certain notes or passwords/codes I want shared to certain people that I wouldn’t bother having set up with a lawyer.

### 1/5 — A scam

*2025-08-19*

I downloaded this app to investigate how it works and what it does. Once I understood the lack of customization, options or explanations I ended the trial early. Now, I am being harassed by repeated emails to verify “my existence”. I am glad I did not pay for such a scam.

**Developer response:** Issue resolved in version 1.1.1

### 5/5 — Fantastic

*2025-06-20*

Very smooth experience, great UI, does exactly what I needed - might be the only platform I’ve found that does.

### Is my data secure with the Dead man's switch app?

### What happens if I lose my phone or delete the app?

If you lose your phone or delete the app, you will receive an email to confirm your presence. This is a safeguard to ensure your package is not delivered erroneously.

### Does the Dead man's switch app have ads?

### How often is the Dead man's switch app updated?

The latest version of the Dead man's switch app is 1.1.8, which was last updated on April 26, 2026. This indicates a recent update, suggesting ongoing development and support.

## Version history (last 5 releases)

### 1.1.9 — 2026-08-08

This version allows the user to by-pass detection to manually trigger delivery for testing purposes, as well as reset their account after delivery

### 1.1.8 — 2026-04-26

In this version we’ve updated all dependencies in the mobile application and engineered our own module for detection by Steps.

### 1.1.7 — 2026-03-03

We identified edge cases in which the app could be logged out automatically. When this occurs, step-based detection does not function correctly. In these situations, if email or SMS detection is enabled, the user is sent a confirmation message to verify they are present. However, if the app is logged out, step detection cannot resume on its own.

In this release, we’ve improved detection reliability by introducing a URL deep link that works for both email and SMS detection. If the app is logged out and step detection fails, the confirmation message contains a link that opens the app directly. Opening the app refreshes the background task, allowing step detection to resume and continue operating correctly.

### 1.1.6 — 2025-12-29

- added push notification to refresh background detection
- updated detection schedule to be more practical in real life

### 1.1.4 — 2025-12-04

- added help section / user manual
- improved UI for creating packages
- improved explainability of decryption process
