What's New in A Dead Mens Switch

2.4.0

May 28, 2026

v2.4.0 — More flexibility, more reliability. LONGER INTERVALS You can now set your check-in interval up to 30 days. Two new options join the picker: 2 weeks and 30 days. Useful for solo travel, long expeditions, or anyone whose routine doesn't fit a weekly cadence. RELIABILITY FIXES (from real customer reports) • Your streak now resets correctly the moment a missed check-in triggers an alert. Previously a quirk in our database update kept the streak counting past missed alerts. • Snoozing now sets your deadline cleanly to the snooze duration from now, regardless of how much time was left on the clock. Previously a snooze while time remained could push the next deadline well past your interval. • Notification emails now render correctly in Gmail and Apple Mail when those clients force light mode. Previously dark-theme styles could appear as faint gray text on white. • Improved email deliverability to iCloud and Gmail. Added SPF, DKIM, and DMARC authentication on the sending domain, plus one-click List-Unsubscribe and stable Message-IDs. Fewer legitimate alerts will land in spam. QUALITY OF LIFE • A What's New page in Settings stays current - open it any time to see what changed. Thank you to the people who wrote in with detailed reports. Every bug fix in this release came from a real customer message. Keep them coming.

User reviews

Broken, right out of the box.

Right off the bat the account creation set up scheme doesn’t work. When you add your email address and a password it comes up with a meaningless error message that says invalid blah blah format. Um really? What am I supposed to do use Chinese characters? Klingon? Why go to all the work of making an app without bothering to test it?

Almost perfect

Good app but definitely needs push notification and text notification options.

Im Moment noch völlig unbrauchbar

Der Entwickler kapiert es einfach nicht! Der Farbgebung und der Text der Benachrichtungsmails sind (immer noch!) extrem schlecht - unfreundlich, unseriös, farblich unlesbar! Man kann es definitiv nicht schlechter lösen als in dieser App!

Alte Rezension:
Viele Dinge sind noch nicht gut gelöst bzw. wirken sehr unfertig:

- System- / Notifikations- und Test-Mails sind praktisch UNLESBAR (hellgrau / hellgrün / hellrosa auf weißem Hintergrund!)

- Der Text der Benachrichtigungen wirkt nicht besonders seriös und auch sehr unfreundlich.

- iCloud-Mail-Adressen funktionieren als Notfallkontakt überhaupt NICHT! Welche anderen Adressen sonst nicht??? So etwas MUSS funktionieren!

- Von 4 testweise eingerichteten nicht-iCloud-Kontakten erhielten nach Ablauf auch !NUR 2! eine Benachrichtigung…

- Eingabe von E-Mail-Adressen arbeitet nicht gut mit iOS zusammen

- Intervall nur bis 1 Woche möglich

In der jetzigen Form würde ich mich niemals auf diese App verlassen!

Response from developer

The time you got in we were doing security updates where every user has to verify the account and every emergency contact has to verify their email. This is related to spam emails being sent to people who don't even use the app. Try verify all your accounts and you will see a difference!!! Hope after that u will see a change.
