NudgeCal: Calendar Alerts

Brian Brammeier

About this app

NudgeCal replaces Android's basic calendar notifications with a smarter, more reliable alert system that puts you in control.

Never Miss an Event
Calendar alerts that don't get lost. Snoozed events automatically re-schedule when your phone reboots — your "snooze until 2 PM" survives a battery swap or overnight restart. Accidentally swiped a notification away? Restore it from the Dismissed list with one tap.
Undismissed events can re-fire at intervals you choose, so important meetings keep nudging until you act. App updates won't drop pending alerts.

Flexible Snooze
Snooze events for 15 minutes, 1 hour, 4 hours, or any custom duration up to weeks ahead. Pick a date and time, or set your own preset list so the right options are always one tap away.

Quiet Hours
Schedule silent periods so calendar alerts won't disturb you during sleep or focus time. Notifications arrive silently and wait for you.

Per-Event Muting
Mute noisy recurring meetings without dismissing them. Stay aware of the event without the repeated alerts.

Clean, Modern Interface
Events are grouped by time (Now, Today, Tomorrow, This Week) with calendar color coding, swipe-to-dismiss with undo, and a configurable retention window for dismissed records — so a swipe is never a permanent mistake.

Multiple Calendar Support
Choose exactly which calendars to monitor. Each calendar's color is carried through to notifications for quick identification.

100% Private
NudgeCal works entirely on your device. No internet connection needed. No accounts, no tracking, no ads. Your calendar data never leaves your phone.
