AirMQTT is a native MQTT client for Mac, iPhone, iPad and Android. Connect it to your MQTT broker to publish messages, monitor topics and repeat device commands.

Create a named connection profile, then open it to enter your broker host, port and authentication settings. Select the protocol and transport your broker supports, then connect.

Select a connection, choose or enter a topic, type your message, and hit 'Publish'. You can also save specific messages as quick actions for one-tap sending.

Yes—navigate to the 'Messages' area of your connection to see real-time incoming messages. Use the topic filter to display only the messages that matter.

Apple devices use iCloud for saved connection profiles and settings. Android stores profiles locally. AirMQTT does not provide shared synchronization between Android and Apple.

Message history is kept in the running session, not as a permanent archive. Export the session as JSON or TXT when you need a lasting record, before clearing the history or closing the session.

Pro adds more topic filters, quick-action buttons, history export and app customization. Available options and current prices are shown in the app for your platform.
