2) Detailed Description (Body)

Tomorrow Timer is a timer/stopwatch/alarm app that displays not only the remaining time but also the "when it will ring (end/alarm time)" (based on the date/AM/PM) to avoid confusion even when using long timers (today → tomorrow).

The app operates offline (can be used without internet access), and settings are stored only on the device.

- Timers can be set from the current time until tomorrow (the next day).
- The scheduled end (alarm) time is intuitively displayed.
- Example: "End: Tomorrow, January 6th, 2:40 PM."
- Displayed on the screen and in the notification (ongoing notification), so you can immediately see when it will ring. - Instant control from the notification bar
- Quickly pause/resume/stop the running timer/stopwatch from the notification bar
- Multiple timers are displayed in an easy-to-view list format
- Quick presets

Today's Added/Improved Features (2026-01-05)

- Added "Change Sound" feature (user mp3 selection)
- Tap the folder button in "Change Sound" at the bottom of the alarm editing screen to select an mp3 file from your Downloads folder, etc., to use as an alarm sound. - If the selected file is deleted or inaccessible, the app will automatically revert to its default built-in sound.

4) Permission information (available as is in the Play Console "Permission Description")

The following permissions (or system settings) may be used for the app's "Accurate notifications / Notification bar control / Background stability / Alarm sound playback." The permissions displayed may vary depending on the Android version/device policy.

- Notification permission (POST_NOTIFICATIONS, Android 13+)
- Required to display ongoing notifications and send timer/alarm end notifications.

- Exact Alarm permission (SCHEDULE_EXACT_ALARM, USE_EXACT_ALARM, Android 12+ depending on device/OS)
- Schedules an "Exact Alarm" to ensure that the timer/alarm sounds at the set time.
- On some devices, you may need to enable "Allow Exact Alarm" in the Settings screen.

- Foreground Service (FOREGROUND_SERVICE, FOREGROUND_SERVICE_MEDIA_PLAYBACK)
- Used to ensure stable operation of the timer/alarm even when the app is in the background, and to play alarm sounds.

- Keep screen awake/locked (WAKE_LOCK)
- Reduces delays/missed notifications by keeping the CPU and operation active when an alarm sounds.

- Vibrate (VIBRATE)
- Used for alarm vibration.

- Full-screen notification (USE_FULL_SCREEN_INTENT)
- Can be used to clearly display full-screen notifications when an alarm sounds (depending on device settings).

- Request battery optimization exceptions (REQUEST_IGNORE_BATTERY_OPTIMIZATIONS, optional)
- Notifications may be delayed on some devices (e.g., due to manufacturer power-saving policies).

If desired, the user can request/prompt for the "Battery Optimization Exclusion" setting.
- The app will still function without this permission, but the accuracy of long-term timers/alarms may be affected.

About audio file (mp3) selection
- The app does not scan the entire storage and only accesses audio files manually selected by the user in the "System File Picker." - The file itself is not transmitted externally; only the reference information (URI) required for playback is stored on the device.
- If the selected file is deleted, the app automatically reverts to the default built-in sound.
