Everything in one app

One screen runs the whole building.

No racks of equipment, no technician on call. Announce handles your bells, announcements, and alerts from a phone or tablet.

Automated schedules

Set bells and announcements to play at the right time, every time. Different schedules for different days.

Record & import audio

Record your voice on the spot or bring in audio files you already have. Build a library you reuse.

Live mic paging

Tap once and speak directly through your speakers, with optional chimes before and after.

Emergency signals

Powerful alert tones and pre-recorded messages, protected by hold-to-confirm so they never fire by accident.

Built-in sound library

Professional bells and chimes included out of the box — or add your own and organise them by type.

Works completely offline

No internet, no accounts, no data leaving the device. It keeps working when the network doesn't.

Three steps

Keep your speakers. Change how you use them.

If your building already has PA speakers, you're most of the way there. Announce becomes the brain that drives them.

STEP 01

Connect to your existing PA

Link your device to the speakers you already run. Nothing to rip out, nothing new to install.

STEP 02

Record & schedule

Record your voice or import audio, then schedule it to play at whatever times you choose.

STEP 03

It plays automatically

Bells, announcements, and emergency alerts go out on time — or live, the moment you tap.

Full guide

The complete getting-started guide

Everything from first launch to running a live announcement — tap any section to expand.

  • No account, no internet. Open the app and use it — nothing is set up online and no data leaves the device.
  • It plays through your connected speaker or PA. Announce sends audio to whatever output the device is connected to. Connect to your PA the way you normally would, then confirm the output in the app before going live.
  • Do a test first. Run one low-volume test before you rely on it, so you know the audio reaches the right speakers.

The bar along the bottom of the screen is how you move around:

  • Dashboard — see what's playing next and what's scheduled today.
  • Record — record your voice or import audio into your sound library.
  • Announce — set up and play announcements.
  • Schedule — create and manage automated bells and timed announcements.
  • Settings — audio output, preferences, and app options.

Two quick controls sit at the top-right of the Dashboard: Live Mic and Emergency.

The first screen you see. At a glance:

  • Next Bell — the name of the next scheduled item and a live countdown.
  • Today's Schedule — everything queued for today, with a Next marker on the upcoming item.
  • Active indicator — a badge showing how many schedules are switched on.
  • Live Mic & Emergency shortcuts in the top-right.

If the countdown is running and the right item shows as next, your schedule is working.

Everything Announce plays lives in your sound library. Fill it three ways:

  1. Record your own voice — tap record, speak, and save with a clear name (e.g. “Period 1 Bell”).
  2. Import audio files — bring in audio you already have.
  3. Use the built-in sounds — tones like School Bell Long, Classic Alarm, and 3 Tone Chime are included.

Your audio is sorted into Recordings, Imported, and Built-In, and each clip has a play button and shows its length so you can preview it.

The heart of the app — set it once and it plays automatically.

  1. Go to Schedule and add a new entry.
  2. Set Time — choose when it plays.
  3. Repeat Days — Everyday, Mon–Fri, or specific days.
  4. Choose Sound — pick a clip from your library.
  5. Tap Done to save.

Each entry shows its time, name, repeat pattern, and an on/off toggle — flip it off to pause without deleting. New to the app? Start with a single bell or schedule to see it run on your own speakers before building a full day.

  1. Tap Live Mic at the top-right of the Dashboard.
  2. Confirm the output at the bottom shows your intended speaker.
  3. Tap the microphone button to start — you'll see a live waveform and timer.
  4. Speak normally, then tap again to stop.

Toggle Mode switches between tap-to-start/stop and hold-to-talk. Pre-Chime / Post-Chime add an attention tone before and after, and a loud-volume reminder helps protect hearing.

The Emergency button gives fast access to alert tones — like an evacuation signal — without digging through menus. Because an accidental alert is serious, it uses hold-to-confirm: select the alert, then hold to confirm before it broadcasts.

Set this up in advance. Record or assign emergency messages before you need them, and run a low-volume test so you know which button does what under pressure.

Confirm your audio output and adjust preferences here. Check your output first whenever a broadcast isn't reaching the right speakers.

  • Keep the device charged or plugged in — a dead battery is the most common, most preventable failure.
  • It works fully offline, so a network outage won't stop your bells — just keep the device connected to the speaker output.
  • Test after any change to a schedule, recording, or output.
  • Designate a backup operator who knows Live Mic and the Emergency button.

Built for institutions

Made for the people who keep buildings running.

Schools & districts

Bells that ring on time, alerts that reach everyone.

Run period-change bells, daily announcements, and evacuation messages from one place. When seconds count in an emergency, the message goes out clearly and immediately.

Religious institutions

Simple enough for any volunteer.

No technician, no training session. A volunteer can schedule a service chime, play a recorded message, or speak live — all from a phone they already know how to use.

When it matters most

An announcement system has one job: don’t fail.

The most common reason a PA fails is a dependency that wasn't there when you needed it. Announce is built to remove those dependencies.

No internet required

Everything runs on the device. A Wi-Fi or network outage won't stop your bells or your emergency alerts.

Accidents can't happen

Emergency alerts use hold-to-confirm, so the evacuation tone never goes out from a stray tap.

Test it any time

Run a low-volume test in seconds to confirm the right message reaches the right speakers before you rely on it.

You stay in control

No accounts and no cloud lock-in. Your audio and your schedules live on hardware you own.

Questions

The things buyers ask first.

Announce is designed to drive standard public-address setups through the audio output your speakers already use. The best way to be certain for your building is a quick test on your own system — if you're unsure about your setup, reach out via Support and we'll help you confirm it.
No. Everything runs offline on the device. Scheduled bells, live paging, and emergency alerts all keep working even if your network is down.
No sign-ups, no logins, no setup portal. Open the app and use it — which is why a volunteer or non-technical staff member can run it without training.
₹4,999 for lifetime use — a single one-time purchase, with no subscriptions and no per-seat fees. Want to try before committing? Add a single bell or schedule and run it on your own speakers first.
Because Announce runs entirely on the device and connects to your speakers directly, a network outage doesn't take your alerts offline. Your evacuation message is right there, ready to play.
