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.

Know which apps are growing, where they earn, and how people find them. ASO Analytics brings your App Store sales, subscription reports, and keyword rankings together on iPhone, iPad, and Mac. Built for indie developers, it connects directly to Apple with your own App Store Connect API key. Your sales data never passes through our servers. FOLLOW YOUR APP BUSINESS • See downloads and revenue by week, month, or quarter. • Switch between customer prices and developer proceeds, with revenue converted into your preferred supported currency. • Follow subscription performance and monthly recurring revenue. • View impressions, product page views, and conversions when Apple's analytics reports are available. • On Mac and iPad, open a portfolio overview with totals, app performance changes, keyword movements, and top markets. TRACK YOUR KEYWORD POSITIONS • Check rankings from the App Store's own search across the markets you choose. • Follow rank history and see which keywords move up or down. • Explore Apple's search suggestions and the apps appearing at the top of each search. • Compare estimated keyword popularity and difficulty, and sort your tracked list by either score or position. • Keep notes alongside each keyword's history. Popularity and difficulty are ASO Analytics estimates, not search-volume figures supplied by Apple. Automatic rank checks run when the app is open and when background time is available. FIND MARKETS WORTH A CLOSER LOOK Compare downloads and revenue by country. Review localization coverage against a year of installs to spot markets where your listing may need another language. Insights include context when your app's install history is still small. KEEP CONTROL OF YOUR DATA Your API key stays in the device's Keychain. Reports are processed on your device, and stored data syncs through your private iCloud database. No ads, advertising identifiers, or usage analytics.
