Pulse MQTT

Pulse MQTT is a fast, native client for reading and monitoring MQTT brokers on iPhone and iPad — built for makers, smart-home tinkerers and IoT developers. CONNECT TO ANY BROKER • Plain, TLS and WebSocket connections • Username/password auth and self-signed certificates • Save multiple broker profiles; passwords kept in the Keychain • Or tap "Try a public test broker" to start in seconds SEE EVERYTHING LIVE • Real-time message feed with pause, filter and retained-only view • Hierarchical topic tree that stays smooth even with thousands of topics • Full message detail: QoS, retained flag, size and timestamp UNDERSTAND YOUR DATA • Automatic decoding: pretty-printed JSON, epoch timestamps turned into dates, hex and base64 decoded, and long arrays summarised instead of endless zeros • Per-topic charts for numeric and JSON fields — pick any field to plot • Star topics to keep a longer history that survives app restarts • Export a topic's history as CSV or JSON OPTIONAL AI INSIGHTS • "Explain with AI" describes what a device and its payload likely mean • Optional and off by default — bring your own Anthropic API key • Everything else works fully without it Pulse MQTT has no accounts, no analytics and no tracking. Your broker traffic stays between your device and your broker.
