Audio Scheduler

Audio Scheduler plays your audio files automatically at the exact times you choose. Set it up once, and your tablet or phone becomes a dependable automatic bell, announcement player, or reminder system that runs every day without anyone pressing a button.

Perfect for schools, madrasas, mosques and prayer rooms, offices, shops, restaurants, factories, warehouses, gyms, clinics, and homes. Use it for class bells, break and lunch signals, prayer-time reminders, shift changes, opening and closing announcements, music at set hours, or any sound that must play on time.

★ SCHEDULE EXACTLY THE WAY YOU NEED
- One-time daily schedule – pick the hour and minute, then choose the days: every day, Monday–Friday, Monday–Saturday, weekends, or any custom combination.
- Repeating interval – play every 5, 10, 15, 20, 30, or 45 minutes, or every 1, 1½, 2, 3, or 4 hours, between a start time and an end time. Example: 07:00–15:00 every 30 minutes.
- Live preview – see every play time for the day before you save, so there are no surprises.
- 12-hour (AM/PM) or 24-hour clock – switch anytime.

★ USE YOUR OWN SOUNDS
- Choose MP3, WAV, OGG, M4A, and other audio files stored on your device.
- Files are copied safely into the app, so your schedules keep working even if the original file is moved, renamed, or deleted.
- Set the volume for each schedule, so a bell can be loud and background music can be soft.
- Repeat each audio 1 to 10 times every time the schedule fires.
- Test play button to check any sound instantly before saving.

★ SMART QUEUE – NO MORE CUT-OFF AUDIO
When two or more schedules fall on the same minute, or a new schedule starts while another audio is still playing, Audio Scheduler plays them one after another in order instead of cutting each other off. Overlapping schedules are clearly marked in the list and in the editor, so you always know what will happen. You can skip to the next audio or stop everything with one tap.

★ RELIABLE, EVEN IN THE BACKGROUND
- Plays on time even when the screen is off or the app is closed.
- Schedules are restored automatically after the device restarts or the time zone changes.
- Uses precise alarm timing designed for on-time playback.
- A notification shows what is playing, with Skip and Stop buttons.

★ DESIGNED FOR TABLETS AND DEDICATED DEVICES
- Large, easy-to-read clock and date on the main screen.
- "Next schedule" card with a live countdown.
- Clean, modern dark interface that is comfortable to look at all day.
- Multi-column layout on tablets, single column on phones.
- "Keep screen on" mode for wall-mounted tablets, reception desks, and control rooms.
- Enable or disable any schedule instantly with a switch – no need to delete it.

★ SIMPLE TO USE
1. Tap "Add schedule".
2. Give it a name, such as "Morning bell" or "Lunch break".
3. Choose a time or an interval, then select the days.
4. Pick an audio file and set the volume.
5. Save – done. The audio will play automatically at the scheduled time.

★ WORKS ON OLDER DEVICES
Audio Scheduler is lightweight and supports Android 5.0 and above, so you can give an old tablet or phone a new job as a dedicated bell or announcement device.

Available in English and Bahasa Indonesia. Follows your system language, or choose one manually from the menu.

★ TIPS FOR BEST RESULTS
- Allow the "Alarms & reminders" permission if your device asks for it.
- Turn off battery optimization for Audio Scheduler so schedules always run on time.
- Some manufacturers add their own battery savers; if audio plays late, allow Audio Scheduler to run in the background in your device settings.
- Keep the device connected to power if it is used as a permanent bell system.

★ PRIVACY
Your audio files and schedules stay on your device. Audio Scheduler does not require an account.

Audio Scheduler is free to use and supported by ads.
