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.
