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.
