push.tt: PTT Walkie Talkie

push.tt turns a phone or a rugged handset into a walkie-talkie that works wherever there is a mobile or Wi-Fi signal - with none of the range limits, licences or tower costs of two-way radio.

Press to talk. Everyone on the channel hears you at once.

WHAT YOU GET
- Instant push-to-talk over cellular and Wi-Fi, with no range limit
- Channels for crews, sites and shifts, plus one-to-one direct messages
- End-to-end encrypted voice, video, photos and text on organisation and private channels
- Encrypted voice and video calls
- Live video from the field, so a dispatcher sees what you see
- Message history you can play back
- Works on ordinary phones and on rugged PTT handsets with a physical paddle

BUILT FOR WORK
- A dispatch console for the desk, with a live map of your units
- Emergency alerts
- On-device transcription: speech-to-text runs on the phone that recorded it
- Device management for company-owned handsets

PRIVACY, STATED PLAINLY
Voice, video and messages on organisation and private channels are end-to-end encrypted. They are sealed on your device to each recipient's key, and our servers relay bytes they hold no key for. Public channels are labelled in the app and are not end-to-end encrypted, because anyone may join one.

There is no forward secrecy yet. A stolen device key could expose that device's past messages. We would rather write that down than let a padlock icon imply more than it delivers.

You can delete your account and its data from Settings - Your account, or at https://pushtt.app/delete-account/

push.tt is free to use. Optional paid plans and account credit cover phone numbers, minutes, eSIMs and extra seats.
