## What is OKURERUNA！?

A new kind of reminder that physically wakes you up before your events with intense vibrations. No more missed meetings or oversleeping.

Key Features:

- Calendar Sync: Automatically fetches events from your selected calendars
- Customizable Timing: Set alerts from 1 to 30 minutes before events
- 3 Vibration Levels: Normal, Strong, or Extreme — choose what works for you
- Repeated Notifications: Multiple alerts leading up to the event so you wont miss it, even in silent mode
- Per-Event Mute: Silence notifications for specific events with one tap
- Urgency Display: Visual countdown with color changes and pulsing animations as the event approaches
- Swipe Navigation: Quickly browse events by day with left/right swipes, jump back to today with one tap
- Auto-Resume: Vibration automatically resumes when returning from background until you tap to stop
- Custom Alarm Sound: Background notifications include a custom alarm sound and system vibration

Perfect For:

- Heavy sleepers who need strong alerts before morning meetings
- Busy professionals juggling back-to-back events
- Students who lose track of time between classes
- Anyone who keeps their phone in silent mode

The app features an intuitive design with a large stop button to quickly silence vibrations. Background notifications with custom alarm sounds ensure you are alerted even when the app isnt in the foreground.

Select only the calendars you want to monitor, and let the app handle the rest. Your events, your rules, your peace of mind.
