The button on the side of the phone, wired to the radio.
A push-to-talk app is only as good as the key you press without looking. Respondr maps the real hardware button on rugged phones, PoC radios, Bluetooth accessories and dispatch consoles — and it opens the same controls to any Android device that can fire an intent.

Press the hardware button, not the screen.
On a Samsung Galaxy XCover the XCover key transmits and the emergency key raises an SOS. On RugGear, Inrico, Telox, IRISIO, iSafe and Siyata devices Respondr binds the vendor PTT key the same way. Gloves on, screen off, in the rain — the key still works.

Add a key to any phone.
A phone without a PTT key becomes one with a Bluetooth button clipped to a strap, or a USB-C speaker-microphone. Respondr detects the device, reads its button map, and remembers the assignment.

Consoles built for a dispatcher’s desk.
In the control room the operator needs dedicated keys, a gooseneck microphone and a screen that never sleeps. Respondr runs on Tipro console hardware in three sizes, self-contained — no server required on site.

What makes a device work
The four ways Respondr reaches a physical button, and what you get once it does. If your hardware fits one of these, it works — it does not need to be on a list.

Frequently asked questions
Yes. Respondr binds the XCover key through the Samsung Knox hardware-key interface, so pressing it transmits and releasing it stops — the same behaviour as a radio. On models with a dedicated emergency key, that key raises an SOS alert instead. No extra accessory is needed.
Almost certainly. Respondr runs on any current iPhone or Android phone. If the device has a programmable key that can send an Android intent, it can drive push-to-talk, SOS, channel change and replay — the intent names are documented and open. Tell us the model in the demo and we will confirm.
Yes. A BluSkye RSM or a PTT Z01 pairs with any phone running Respondr and turns it into a push-to-talk device with a real key. Assignments are stored on the phone and survive restarts.
No. A dedicated key helps when the user wears gloves or cannot look at a screen, which is why rugged phones and PoC radios exist. For office, vehicle and supervisor roles, an ordinary phone with the on-screen control is usually the right tool.
Through Android Enterprise Device Owner, with Esper or another MDM. The server address, the user and a provisioning token are pushed as managed configuration, permissions are pre-granted, and kiosk mode locks the device to Respondr. Zero Touch enrolment is supported on RugGear, Inrico and Telox hardware.
The vendor key intents reach Respondr while it runs in the background, which is its normal state — it holds a foreground service so audio and alerting keep working with the screen off.
