Signed in as the Demo organisation admin. Dispatch activity appears on the handset beside it.

This handset shares the Console's private Demo organisation. Its account and data are deleted after 24 hours.

Securely pairing the Demo organisation across both screens…

The push.tt talk screen: the dispatch channel with five people connected, the emergency control and the hold-to-talk ring

Instant

Turn any phone into the best radio on the planet

Push a button and talk. Audio plays the moment it arrives, whatever else is on the screen — so nobody stops what they're doing to answer a call.

The push.tt channels screen: five organisation channels with live connected counts and unread work mail waiting

The push.tt Apps screen: Jobs, Aviation, Customer links, Driver groups, Email, Fares, Rides, Shifts, Weather and World Phone

Everything together

Channels, work apps and email on one issued handset

Recents, contacts, channels and built-in work apps live in one consistent shell. Admins decide what appears; employees do not manage another install or sign-in.

Channel membership and connected counts at a glance
Admin-enabled Apps appear without a second install
Built-in Email uses the employee's work identity

Built-in work email

Give every employee an email with their radio

The issued handset becomes a complete work identity: push-to-talk and a real inbox at your company domain. No personal Gmail, no separate mail app, no second login.

Work apps

The job itself, on the same handset

Dispatch, tracking, chain of custody and live traffic are built in — not a second app to install, a second login to lose, or a second device to carry. An admin switches one on and it appears on every issued handset.

Security

The server relays audio it cannot hear

Direct messages and private channels are end-to-end encrypted. Keys are generated on your device and stay there, so what reaches our servers is scrambled — and stays that way.

# Key agreement — device keypair never leaves the phone
X25519 ECDH → HKDF-SHA256

# Every voice frame and message body
AES-256-GCM · fresh 96-bit nonce per frame

# Channel keys, sealed to each member's public key

What we don't claim

Public channels aren't end-to-end encrypted — anyone can join one, so the guarantee would be theatre. They get TLS and encryption at rest instead, and the app labels which is which. We also don't have forward secrecy yet: a stolen device key could expose that device's past messages. A ratchet is on the roadmap. We'd rather say so than let a padlock icon imply more than it delivers.

Your organisation holds its own key Compliance archives are decrypted in your admin's browser with a key we never receive. Your org can read its records. We can't.
Transcription runs on the device Speech-to-text happens on the phone that recorded it, and the transcript is encrypted before it's sent. Searchable voice without handing anyone the audio.
Nothing switches on quietly Retention and AI are off by default, need an explicit acknowledgement of what they change, and are labelled in-app for everyone in the conversation.
An audit trail that includes us Every administrative action is recorded — including each time somebody opens your message archive.

Built for the field

Everything a shift actually needs

Emergency alerts

A held button raises an alarm that reaches everyone in the channel — including people who set themselves to Busy. It stays live until somebody clears it.

Channels and crews

Channels for the team, direct calls for one person, presence that shows who's actually connected — not just who installed the app.

Clear in loud places

Echo cancellation and noise suppression tuned for engines, wind and warehouse floors, with earpiece, speaker or Bluetooth routing.

Solo mode

Heads-down on a job? Solo plays only the people you've starred. Everything else still arrives quietly — you simply aren't interrupted.

Compliance when required

Retention windows, a searchable archive and an audit log — enabled per organisation and visible to everyone they affect.

Runs in the background

Screen off, phone in a pocket. Audio keeps flowing, and a signal indicator warns you before you key the mic on a bad connection.

White label

Ship it as your own product

Resell push.tt under your own name and store listing, or apply your enterprise's branding for internal use. Same platform, your identity.

The push.tt talk screen in the default orange identity — push.ttThe default. Everything beside it is the same platform.

FieldCommA reseller build — own name, icon and store listing, with its own tenant.

Your companyEnterprise branding applied at sign-in. No separate build, no review.

These are the same handset, minutes apart. The identity is a setting on the organisation, applied when the employee signs in — not a separate build.
