High-end, customizable, Bluetooth control for Arduino Projects Connect to and control your Arduino project with this easy-to-use Bluetooth Serial Monitor + Controller Send/Recieve Data - now even with custom voice commands utilizing speech recognition for keywords set by the user Great for any IOT project Command your Drones to take off Tell your Smart Lights to Dance Ask your Robot to bring you a drink Or keep it simple and turn an LED on with nothing but your voice Very easy-to-use GUI Automatically searches for Bluetooth Devices and Bluetooth-enabled Arduino boards or boards with a bluetooth module attached Send data as String format to your boards with whatever you programmed your Arduino to recognize and Receive data back in the Serial Monitor below New features continually added, newest feature is Speech Recognition For D-Pad: Set what Data string sends when each button is Pressed/Released (you can also leave onRelease() blank to send null) Suggestions on next features to add are welcome. Next in line are accelerometer control and if-statement controlled Data-sends for received response from the Arduino Device being controlled. If you have an idea leave it below or contact us.
JSON Master

JSON Master is a JSON viewer and editor for the things you actually do all day: find the value, copy its path, copy the branch, and work out what a field really contains. Every document is shown two ways, as a tree and as coloured source, and both are the same file. WHAT MAKES IT DIFFERENT - Every path is ready to paste, in whichever form you need it: dot, JSONPath, brackets, jq, Swift or JSON Pointer - The inspector explains what a value really is: Unix timestamps as dates, JWT tokens decoded, base64, ISO dates, string length, integers beyond 2^53, duplicate keys - Expand embedded JSON, the escaped string every webhook and log line contains, unwrapped in place - Syntax colour that holds even when the document does not parse, which is exactly when it helps - An untouched file is saved byte for byte as it arrived, and a broken one still opens with the line and column of the error ALSO INSIDE Format and minify, sort keys, remove empty values and duplicate keys, JSON Lines to array, JSONPath queries, document summary, structural compare, type generation for Swift, TypeScript and JSON Schema, JWT decoding, export to CSV. Designed like an amber monitor: warm near-black surfaces, phosphor text, monospaced throughout. Seven interface languages, switching without a restart. No account, no tracking, no analytics, no network access. Your documents never leave your device. Universal app for iPhone, iPad and Mac.

Verdict
The clearest difference is iOS requirement: Arduino Bluetooth Pro at 12.0 against JSON Master's 18.0. On price, ads, in-app purchases and device support there is nothing between them.
