Connect to your broker and the topic tree fills in within seconds, with the latest value next to each topic. Tap one to see the value in large type, a sparkline of how it moved, and the JSON split field by field. FOUR SCREENS, ONE JOB EACH • Topics: the tree of what your broker publishes, with filters for what changes, what is retained, what you pinned • Board: pinned topics as live tiles, so one look tells you the greenhouse sits at 21.4 °C and the pump went quiet 6 minutes ago • Log: messages in order, with presets for errors, your own publishes and retained values • Publish: a topic, a payload, Send. QoS, retain, content type and expiry sit one tap away USE IT TO • Watch Home Assistant, Zigbee2MQTT, Mosquitto and ESPHome without opening a laptop • Find the topic a new device announced itself on • Read a JSON payload by field and compare it with the message before • Send a test message and see what the broker answers, including a refusal • Clear a retained payload that keeps coming back WHEN IT WON'T CONNECT Connection Doctor walks the connection in 13 stages and names the one that failed: DNS, TCP, TLS handshake, certificate chain, expiry, hostname, ALPN and SNI, CONNACK, authentication, protocol version, and a write test against the broker ACL. You get the stage, the reason and what to change, instead of a red banner. PRIVACY Values that look like tokens, passwords or keys stay behind a tap. Exported logs carry hashed topics and metadata, no payloads. Anonymous crash and usage diagnostics are on by default and switch off in Settings. No ad tracking, no data sold. PRO The app is free: watch topics, read payloads, publish with QoS and retain, run the Connection Doctor, pin five topics to the Board. Pro is a one-time unlock with no subscription, and it covers the part that runs while you look elsewhere: widgets on the Lock Screen and Home Screen, pins without a limit, history that survives a restart, whole-broker discovery, more broker profiles, one certificate reused across every broker, saved commands with Siri and Shortcuts, log export as CSV or JSON, and the full Doctor report to share. Bought the paid app before it went free? You keep Pro at no cost. WORKS WITH Home Assistant, Mosquitto, Zigbee2MQTT, ESPHome, Node-RED, ESP32 and ESP8266, and any broker speaking MQTT 3.1.1 or 5.0 over TCP, TLS, mTLS or WebSocket. REQUIREMENTS • iOS 17 or later, iPhone and iPad • Local Network access for brokers on your LAN Demo mode lets you look around before you connect anything.

About

Datata

Features

Datata keeps your plans, cellular lines, and devices in one ledger. The home screen shows about how much is left and whether you are using it faster than planned. It fits when: - A yearly plan, a data pack, a travel eSIM, and an everyday line need to live together - Two SIMs use different plans, or one plan covers more than one line - You switch phones or use two devices and want the same ledger under one Apple Account, with optional sync - You check your carrier, then update the remaining amount in the app You can: - Keep more than one plan, with the remaining amount you confirmed and a second figure estimated on this iPhone - Link a plan to a line, or link one plan to several lines - Adjust the remaining amount when the estimate is off - Record a stretch of use on the Lock Screen and in the Dynamic Island - See remaining data in a Home Screen widget - On Apple Watch, see what is left and start or stop a recording (usage is still estimated on iPhone) - Optionally sync plans and confirmed usage with iCloud (on this iPhone only, unless you turn sync on) Figures come from on-device cellular sampling and your adjustments. They are for remaining data and pace. They are not a substitute for a carrier bill or the totals in Settings → Cellular. At important moments, check with your carrier and update the remaining amount in the app. The Apple Watch does not yet keep its own cellular ledger. The free tier covers 2 plans, with iCloud sync and viewing across devices. A one-time purchase, Datata Pro, unlocks more active plans and full features on additional devices. People who downloaded a TestFlight build before 0.1.0 (45) and opened it keep the full release.

Verdict

The call

MQTT Commander and Datata are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
