Description
Stay aware of every hour with visual and vibration-based chimes.
00 Hourly Countdown is a standalone Wear OS accessibility app that helps users notice the top of the hour (:00) and the half hour (:30) without relying only on sound.
The app is designed especially for people who are deaf or hard of hearing, as well as users who need silent, wrist-based time awareness in daily routines, meetings, focus sessions, or other situations where sound may not be noticed or cannot be used.
[Key Features]
Visual Countdown Before the Chime Display a countdown screen before the next :00 or :30 chime. This helps users recognize the upcoming time visually instead of relying only on an audible alert.
Vibration-Based Time Alerts Use vibration to notify the user at the selected chime time. Sound can be turned off for silent use.
Hourly and Half-Hour Chimes Set :00 and :30 chimes independently. Choose sound, vibration, or no alert for each timing.
Custom Vibration Patterns Create vibration patterns by adjusting amplitude and duration for each slot.
Sound and Voice Options Choose beep sounds or voice feedback when audio is useful. Audio can be combined with vibration or disabled for silent use.
Wear OS Standalone Operation Works directly on your Wear OS watch without requiring a constant phone connection.
Tile Support Add a Tile to check the remaining time until the next hourly or half-hour chime at a glance.
Silent Mode Compatibility Optionally follow the watch’s silent mode settings for less intrusive alerts.
[Accessibility Service API Disclosure]
This app uses the Accessibility Service API to automatically display the countdown screen at user-configured hourly or half-hour chime times.
This feature supports users who are deaf or hard of hearing by providing a visual countdown and vibration-based time alert without requiring the user to rely on sound or keep the app open.
The Accessibility Service is used only for this time-based countdown display. It does not read screen content, retrieve window content, monitor user interactions, perform gestures, control other apps, change user settings, prevent uninstall, record audio, collect personal information, or share personal data.
